Amtest Group Expertise Across the Electronics Assembly Process

Amtest Group supports electronics manufacturers across Central and Eastern Europe with complementary technologies and engineering expertise spanning component preparation, PCB assembly, surface protection, inspection, testing and advanced assembly. We help connect equipment and material choices with line layout, process requirements and production support, so that each investment contributes to the wider manufacturing workflow.

Electronics assembly is a combination of interdependent processes. A typical SMT route moves from material preparation to solder paste deposition, paste inspection, component placement, reflow soldering and assembly inspection. Mixed-technology boards also require THT insertion and soldering. Cleaning, dispensing, coating, curing, testing and depaneling are added where the product requires them.

The tables below connect each production activity with Amtest Group’s engineering contribution and relevant solutions. They are a process map rather than a fixed sequence: plasma treatment, cleaning and inspection can occur at several points, and depaneling may take place before or after coating. Die bonding, wire bonding and advanced packaging form additional assembly routes. Engineering support, material control and traceability connect these activities throughout production.

Engineering and Technology Expertise

Amtest Group brings together electronics assembly technologies and practical engineering support for manufacturers across Central and Eastern Europe. Our expertise spans SMT and through-hole assembly, materials processing, surface protection, inspection and reliability verification, factory automation, digital manufacturing and advanced electronics assembly.

We connect product requirements with material behaviour, equipment capability, inspection strategy and line integration. The sections below explain each technology area, Amtest Group’s contribution, typical applications and relevant solutions. Equipment selection, application evaluation, commissioning, training and ongoing support are defined around the customer’s project. Our Centres of Excellence provide facilities for demonstrations, process development and knowledge transfer.

SMT process engineering

SMT mounts components onto PCB surface pads using deposited solder paste and a controlled soldering process. Printing or digital deposition, placement and reflow must work together: paste release, component alignment and thermal exposure all affect solder-joint formation. Inspection data help identify where variation begins rather than relying only on end-of-line rejection.

Amtest Group expertise. Amtest Group helps manufacturers evaluate SMT as a connected process, from materials and paste deposition through placement, soldering, inspection and board handling. We match equipment choices to the product mix, changeover pattern and capacity requirement, and support implementation and process improvement. This helps customers identify interactions between stages when investigating yield or productivity losses.

Stencil printing and digital deposition. Stencil printers control paste transfer through stencil apertures. Selection depends on the smallest features, board support, alignment, paste properties, cleaning and changeover needs.

I.C.T automatic solder paste printers: Automatic solder paste printing combines PCB alignment, controlled squeegee operation and stencil cleaning to support repeatable paste deposition.

ESE stencil printers: Stencil printing systems support controlled solder paste transfer, with mechanical stability and operating functions matched to production requirements.

ioTech C.L.A.D. digital material deposition: Continuous Laser Assisted Deposition (C.L.A.D.) digitally transfers solder paste and other compatible materials from a carrier foil using laser pulses, without conventional stencils or dispensing nozzles.

Component placement. Placement equipment must match component size, package type, feeder format, board dimensions and the balance between changeover flexibility and output. Line balancing considers actual component mix and operating conditions, not nominal placement speed alone.

Hanwha SMT placement systems: SM, DECAN and HM-series placement platforms cover high-mix and volume assembly, with selection based on component range and production output.

Universal Instruments Fuzion placement platforms: Fuzion platforms combine flexible component handling with SMT placement for prototypes, complex assemblies and higher-volume production.

Autotronik SMT equipment overview: A broader SMT range covers stencil printing, pick-and-place and reflow for smaller and medium production series.

Reflow and vapor phase soldering. Convection ovens use controlled heating zones and cooling to achieve the required solder profile. Vacuum reflow can help reduce solder voiding in suitable applications. Vapor phase soldering transfers heat by vapour condensation, with the selected fluid’s boiling point governing the process temperature. Both routes require profiling against solder requirements and component temperature limits.

Heller convection and vacuum reflow systems: Convection reflow ovens provide controlled thermal profiles; vacuum reflow options address solder voiding where the assembly and process require them.

I.C.T convection reflow ovens: Multi-zone convection ovens combine controlled top and bottom hot-air heating with cooling and conveyor transport for PCB reflow soldering.

Exelsius convection reflow systems: Forced-convection reflow ovens combine thermal processing with production data management and features supporting maintenance, cleaning and energy-use control.

ASSCON vapor phase soldering systems: Vapor phase systems transfer heat through fluid condensation to solder assemblies with different thermal masses, subject to validated process profiles.

Typical applications. Automotive control units, industrial controllers, power boards, LED assemblies and high-mix electronics manufacturing services (EMS).

Through-hole assembly and selective soldering

THT inserts component leads through PCB holes before soldering. It is used where connector retention, component construction or current-carrying requirements favour through-hole connections. Odd-form assembly extends automation to connectors, relays and devices that conventional SMT placement cannot readily handle.

Amtest Group expertise. Our THT offering connects component preparation and insertion with selective soldering, manual work and inspection. Amtest Group supports application evaluation and process development around the actual assembly, including solder access and thermal demands. Considering these operations together helps customers plan repeatable production for mixed-technology boards.

Universal Instruments odd-form and THT assembly: FuzionOF, Uflex and dedicated axial or radial insertion systems automate odd-form placement, THT insertion and compatible mechanical assembly operations.

Nordson SELECT selective soldering systems: Cerno, Integra and Synchro systems combine fluxing, preheating and localised soldering, with configurations for batch or integrated production.

Typical applications. Power supplies, industrial controls and mixed SMT/THT assemblies. Lead preparation, manual soldering and THT optical inspection complete the process where required.

Auto dry cabinets and moisture control

Moisture-sensitive components can absorb moisture during storage and handling. Subsequent soldering or rework heating can cause package damage if exposure is not controlled. Auto dry cabinets provide low-humidity storage, with drying or baking options depending on cabinet configuration and component requirements.

Amtest Group expertise. Amtest Group connects cabinet selection with the way components are received, stored, issued to production and returned after use. We help customers compare storage capacity and cabinet capability with the handling procedure, so moisture control fits the production workflow and supports protection against avoidable thermal damage.

Selection considers capacity, humidity recovery after door openings, ESD protection, access frequency and the handling procedure. Dry storage does not automatically reset every device’s floor life; drying and baking must follow the component supplier’s requirements and an appropriate validated procedure.

Typical applications. SMT material stores, high-mix EMS production, component kitting and storage before rework.

X-Treme Series auto dry cabinets: Desiccant-based cabinets provide controlled low-humidity storage for moisture-sensitive components, with drying or baking capability dependent on the selected configuration.

Component counting and inventory management

Component counting verifies quantities for incoming checks, production kitting, reel returns and stock reconciliation. X-ray counters count components in compatible packaging without unwinding the reel. Taped-component counters provide an alternative for appropriate axial, radial and surface mount components.

Amtest Group expertise. Amtest Group helps manufacturers select counting technology for their packaging mix and required workflow. Equipment evaluation includes recognition, accuracy, cycle time, labelling and available data interfaces. Connecting these choices with material handling supports more dependable stock information and reduces time spent on manual reconciliation.

Evaluate the actual packaging, recognition performance, counting accuracy, cycle time and label workflow. Enterprise resource planning (ERP) or manufacturing execution system (MES) integration depends on the selected equipment and interfaces. Counting provides inventory data; full component genealogy additionally requires identification and manufacturing records.

Typical applications. Incoming material checks, production kitting, partial-reel returns and inventory reconciliation in EMS and electronics manufacturing.

Nordson Test and Inspection Assure X-ray component counting: X-ray reel counting supports incoming checks and stock reconciliation, with offline or inline options and available ERP/MES interfaces.

EBSO taped-component counting equipment: Electronic counters count taped axial, radial and surface mount components, providing a handling-based alternative to X-ray counting for suitable packaging.

Component cutting and shaping

Cutting and forming prepare THT component leads for the PCB hole pattern, mounting height and subsequent soldering operation.

Amtest Group expertise. We help match lead preparation equipment and tooling to the component range and intended insertion process. Amtest Group connects these choices with the PCB geometry and production volume, supporting consistent preparation for manual or automated THT assembly.

Tooling must suit lead diameter, body geometry and required dimensions without transferring damaging forces into the component. Consistent preparation supports reliable insertion and reduces assembly variation.

Typical applications. Power supplies, industrial controls and mixed SMT/THT boards using axial, radial or power components.

EBSO component cutting and shaping systems: Manual, motorised and automatic equipment trims and forms axial, radial and power-transistor leads to suit the intended THT assembly geometry.

Manual soldering and workstation tools

Manual soldering supports prototypes, small batches, connectors and touch-up operations. Joint quality depends on surface condition, solder and flux selection, tip geometry, heat transfer and contact time. Temperature control alone cannot compensate for unsuitable tooling or insufficient heat delivery.

Amtest Group expertise. Amtest Group helps configure workstations around the actual soldering or repair task, including heat delivery, tooling, preheating, fume extraction and ESD controls. Equipment selection and operator training support consistent working methods across prototype, assembly and repair operations.

Typical applications. Prototypes, small-batch assembly, connectors, power electronics and production touch-up or repair.

JBC soldering, desoldering and workstation equipment: Temperature-controlled precision and heavy-duty soldering stations, battery-powered tools, hot-air and desoldering systems, preheaters, automatic solder-wire feeders, thermal wire strippers, tip cleaners, fume extractors and accessories support assembly and repair workstations.

Process materials and consumables

Solder alloys, pastes, wires and fluxes must suit the component finishes, thermal process and product requirements. Cleaning agents, conformal coatings and dispensing materials must also be compatible with the assembly and with subsequent process steps. A material change can alter wetting, residue behaviour, adhesion or curing requirements.

Amtest Group expertise. Amtest Group helps customers consider equipment and process materials together when selecting or changing an assembly solution. Our portfolio connects soldering, cleaning, protection and dispensing materials with the technologies that apply them. Reviewing compatibility and handling requirements together helps manufacturers avoid introducing variation through an isolated material change.

Cleaning PCBs stencils and production tooling

Cleaning removes unwanted residues and contamination from assemblies, stencils or tooling. These applications require different processes: a stencil-cleaning cycle cannot simply be assumed suitable for a populated board. Chemistry, component compatibility, rinsing, drying and cleanliness verification must be considered together.

Amtest Group expertise. Our cleaning offering combines equipment and chemistry with the application requirements. Amtest Group helps customers assess whether the task concerns assembled boards, stencils or tooling, then consider compatibility, rinsing, drying and verification. This connects the cleaning investment to the required process result and subsequent coating or assembly operations.

Even when a flux is described as no-clean, the need for cleaning depends on the product environment, coating process and reliability requirements.

Typical applications. Stencil maintenance, PCB cleaning before protection, process tooling and semiconductor production cleaning.

MBtech cleaning machines: Cleaning systems address stencils, electronic boards, semiconductor applications and maintenance tooling, with configurations suited to the required cleaning and drying process.

AB Chimie cleaning and protection materials: Cleaning solutions complement the company’s protective materials, supporting surface preparation and residue removal where chemistry and assembly compatibility are confirmed.

Plasma activation and surface preparation

Plasma treatment can remove certain surface contaminants and modify surface energy to improve subsequent adhesion or bonding. Atmospheric treatment supports selective processing and line integration; chamber-based treatment can suit semiconductor and package preparation. The method, gas, exposure and timing before the next operation depend on the material and application.

Amtest Group expertise. Amtest Group connects plasma equipment choices with substrate compatibility, part handling and the next manufacturing step. Application evaluation considers treatment uniformity, cycle time and the resulting bond or coating performance, helping customers assess surface preparation as part of the complete process.

Plasma is used before compatible coating, dispensing, underfill, moulding or wire bonding processes. It complements an appropriate cleaning strategy and does not replace every form of contamination removal.

Typical applications. Preparation before compatible conformal coating, underfill, encapsulation, moulding and semiconductor bonding.

bdtronic plasma pretreatment systems: Manual, semi-automatic and fully automatic plasma systems, plus integration modules, support surface preparation from small batches to automated production.

Precision dispensing and potting

Dispensing places controlled quantities of adhesives, underfills, encapsulants, sealants or thermal materials at defined locations. Valve or jet selection must match viscosity, filler content, deposit geometry and throughput. Two-component processes additionally require suitable proportioning and mixing, while vacuum potting can help address trapped air in compatible applications.

Amtest Group expertise. Fluid dispensing is a key area of Amtest Group’s process development work and Centres of Excellence. We connect material behaviour with application method, automation, preheating, curing and inspection. Evaluating these interactions helps customers develop repeatable deposits or filled assemblies and select a practical route from application trials to production.

bdtronic dispensing and vacuum potting systems: Manual to automated dispensing systems cover bonding, sealing, thermal materials and vacuum potting, with integration modules and preheating or curing options.

Typical applications. Semiconductor underfill, power module encapsulation, automotive electronics, bonding and thermal management.

Conformal coating and curing

Conformal coating applies a protective polymer layer to defined areas of an electronic assembly. Material selection depends on the operating environment, electrical requirements, substrate compatibility and repair needs. Selective application controls coverage while keeping connectors, test points and other specified areas clear.

Amtest Group expertise. Amtest Group combines coating equipment, protective materials, surface preparation, curing, handling and inspection into a coordinated protection process.

A reliable coating process links surface preparation, dispensing, flash-off where needed, curing and inspection. UV LED, UV arc and thermal or infrared curing are different processes: the energy source, wavelength, dose, exposure and temperature must match the material. Shadowed areas may require a secondary cure mechanism supported by the coating formulation.

Automated coating inspection can assess accessible coverage, keep-out areas and defects. Thickness measurement requires suitable system capability and validation; a fluorescence image alone does not establish thickness or complete cure.

Typical applications. Automotive control units, industrial controls, outdoor electronics and power assemblies requiring protection from their operating environment.

Nordson ASYMTEK selective conformal coating: Selective coating platforms combine application valves and process controls to manage protective material coverage while leaving specified keep-out areas clear.

Optical inspection and X-ray analysis

Inspection should answer a defined question at the appropriate production stage. Solder paste inspection (SPI) measures paste deposits before placement. Automated optical inspection (AOI) evaluates accessible component and solder features; pre-reflow inspection and post-reflow inspection have different purposes. THT systems can inspect insertion and accessible solder joints, including suitable top-side or bottom-side configurations.

Amtest Group expertise. Amtest Group helps customers develop an inspection strategy across paste deposition, SMT and THT assembly, coating, hidden joints and first article verification. We connect inspection capability with the actual defects, access and output requirement. This helps manufacturers select complementary methods and use their results to investigate process variation.

X-ray inspection examines hidden connections and internal structures, including ball grid array (BGA) and quad flat no-lead (QFN) joints. Manual systems support analysis and troubleshooting; automated X-ray inspection (AXI) supports programmed production checks. Available 2D, 2.5D and 3D imaging methods differ by system and application.

First article inspection (FAI) verifies an initial assembly against its specifications before a production run. It helps check component identity, location and position during new product introduction or changeover. FAI complements ongoing production inspection.

Typical applications. New product introduction, high-mix EMS, automotive and industrial PCB assemblies, hidden-joint analysis and coating verification.

Bluiris first article inspection: Optical first article verification checks component identity, location and position against specifications before a production run or after changeover.

Equipment evaluation considers defect coverage, board access, resolution, cycle time, programming effort and false calls. AI-assisted inspection features should be assessed against actual products and acceptance criteria. Inspection results support process improvement but do not establish complete electrical functionality.

Process testing reliability assessment and acoustic inspection

Testing and analysis provide evidence about specific material, process or interconnection risks. Tests use defined conditions and acceptance criteria; an ionic contamination result alone cannot predict every reliability outcome.

Amtest Group expertise. Amtest Group helps manufacturers connect each verification question with a suitable test or analysis method from our portfolio. The assessment considers sample type, acceptance criteria and the evidence needed for development, validation or failure analysis. This supports informed decisions about materials and interconnections while keeping the scope of each test clear.

Mechanical bond testing evaluates interconnection strength using suitable pull, shear or other test methods. Acoustic micro imaging uses ultrasound to examine internal interfaces and can reveal delamination or other defects in compatible packages and materials. It complements X-ray analysis, which responds to different physical properties.

GEN3 solderability, contamination, SIR and CAF testing: Solderability, ionic contamination, surface insulation resistance (SIR) and conductive anodic filament (CAF) instruments assess different soldering and electrical reliability risks under defined test conditions and acceptance criteria.

Nordson mechanical bond testing: Mechanical bond testers apply suitable pull, shear or related methods to evaluate interconnection strength in semiconductor, microelectronic and other compatible assemblies.

Nordson acoustic microscopes and micro imaging: Ultrasonic micro imaging examines internal interfaces in compatible packages and materials, supporting non-destructive identification of delamination and related internal defects.

Typical applications. Process validation, development and failure analysis in PCB and semiconductor manufacturing. Product-specific functional or in-circuit electrical testing may also be needed as part of the overall quality plan; it is distinct from the test equipment described here.

PCB handling magazines and factory automation

Handling equipment connects machines and controls board flow through loaders, unloaders, conveyors, buffers and return systems. Magazine racks support storage and transfer, while suitable ESD controls help protect sensitive assemblies. Handling design must accommodate board thickness, dimensions, weight, component clearance and any production carriers.

Amtest Group expertise. Amtest Group helps plan the connections between production machines, including board flow, buffers, carriers and storage. We assess handling alongside the process equipment so customers can identify bottlenecks, organise changeovers and maintain practical access for operation and service.

CAB PCB magazines and handling products: PCB magazines accommodate different board sizes and support storage, transport and machine loading, helping organise handling while controlling mechanical stress.

PCB depaneling and board separation

Depaneling releases individual boards from a manufactured panel. Router systems suit routed contours and tabs; other separators suit appropriate pre-scored grooves or remaining connections. The method should follow panel design and limit mechanical stress on components and solder joints.

Amtest Group expertise. Amtest Group helps customers compare separation methods against panel geometry, component clearance and required output. Equipment selection includes board support, fixtures, extraction and handling. Evaluating these requirements early supports a separation process suited to the product and its position within the assembly route.

Evaluate support fixtures, cut path, dust extraction, edge quality, component clearance and cycle time. Inline and offline configurations provide different trade-offs for output, flexibility and integration.

Typical applications. Panelised automotive, industrial, LED and consumer electronics boards in inline or offline production.

CAB PCB separators: MAESTRO separators handle suitable pre-scored panels, while HEKTOR equipment separates remaining connections on milled boards using product-appropriate support and tooling.

Digital manufacturing laser marking and traceability

Digital manufacturing connects equipment data with production decisions. Traceability links a product identifier to relevant materials, machine events, process settings and inspection results. Laser marking provides readable serial numbers or codes; the manufacturing records and data connections create the product history.

Amtest Group expertise. Amtest Group connects marking and available machine data capabilities with the customer’s traceability objectives. We help define the equipment interfaces and integration questions before implementation, so identifiers can be linked to useful manufacturing records. The scope follows the selected machines and existing production systems.

Machine interfaces, data ownership and integration scope must be agreed for the selected configuration and the customer’s existing systems.

Typical applications. Product identification, changeover control and the connection of manufacturing records for automotive, industrial and EMS production.

Bridge laser marking and code verification: Futura laser marking systems create product identifiers, while ZOT verification checks panel markings to support readable codes within a traceability workflow.

Electronics manufacturing questions and answers

Manufacturing processes and materials

What is SMT?

Surface mount technology assembles components onto PCB surface pads. A typical process deposits solder paste, inspects it, places components, forms joints through reflow soldering and inspects the assembly. Explore SMT placement.

How do THT and odd-form assembly differ from SMT?

THT inserts leads through PCB holes. Odd-form assembly handles components or assembly operations that require specialised placement, insertion, feeding or tooling. Both can be combined with SMT on the same product. Explore odd-form and THT systems.

What is selective soldering?

Selective soldering applies flux, preheat and molten solder to selected through-hole joints. It is useful on mixed-technology boards where the rest of the assembly should not be exposed to the soldering operation. Explore selective soldering.

How does vapor phase soldering work?

Vapour condenses on the assembly and transfers heat. The selected heat-transfer fluid governs the process temperature. Profile validation remains necessary to meet solder and component requirements. Explore ASSCON systems.

What is stencil-free solder paste deposition?

Stencil-free deposition places paste directly in a programmed pattern. ioTech C.L.A.D. uses a carrier foil and laser-assisted transfer to deposit compatible materials without conventional stencils or dispensing nozzles. Explore ioTech deposition technology.

Why are solder materials and cleaning consumables important?

They influence paste transfer, wetting, residue behaviour and process consistency. Material compatibility, storage and handling must be considered alongside equipment settings. Explore materials and consumables.

Storage handling and preparation

Why use auto dry cabinets?

They provide controlled low-humidity storage for moisture-sensitive components before assembly or rework. Cabinet capability and the storage procedure must match the components and production workflow. Explore X-Treme Series cabinets.

Does dry storage replace baking?

Not in every case. The required procedure depends on component type, exposure history and supplier instructions. Restoring floor life requires a suitable drying or baking procedure rather than an assumption based only on cabinet humidity.

What is X-ray component counting?

It uses imaging and counting software to determine component quantities in compatible reels or packaging without unwinding them. It supports inventory control; identification and system integration are additional steps. Explore component counters.

Why are THT leads cut and formed?

Lead preparation matches the component to PCB hole spacing, mounting height and soldering requirements. Suitable tooling controls dimensions while limiting damage to the component. Explore EBSO equipment.

How are PCB handling and depaneling different?

Handling moves, stores or buffers boards between processes. Depaneling separates individual boards from a panel. Their equipment and support requirements depend on board geometry, component clearance and the production route. Explore handling and depaneling.

Protection dispensing and curing

What does plasma activation do?

It modifies compatible surfaces and can improve adhesion for subsequent bonding, dispensing or coating. The treatment must be matched to the material and validated against the required result. Explore plasma systems.

How do dispensing and conformal coating differ?

Dispensing applies controlled fluid deposits for tasks such as bonding, underfill, sealing or encapsulation. Conformal coating applies a protective layer to specified assembly areas. Each needs material-specific application and curing control. Explore dispensing and selective coating.

Why must the curing method match the material?

UV wavelength and dose, exposure, temperature and secondary cure requirements depend on formulation. An unsuitable curing process can leave material incompletely cured or expose the assembly to excessive heat. Explore curing equipment.

Can coating inspection prove that an assembly is fully protected?

It can verify specified accessible features such as coverage and keep-out areas. Protection also depends on adhesion, cure, thickness where required and the product environment. These may need separate measurements or tests. Explore coating inspection.

Inspection testing and reliability

How do SPI AOI and AXI differ?

SPI checks solder paste deposits. AOI inspects accessible assembly features using optical imaging. AXI uses automated X-ray imaging to assess hidden connections or internal structures. A combined strategy improves coverage when each method is suited to the product. Explore optical inspection and X-ray inspection.

What is first article inspection?

FAI checks an initial assembly against specifications, including component identity, location and position. It supports new product introduction and changeovers before ongoing production inspection takes over. Explore Bluiris FAI.

What do SIR and CAF tests assess?

SIR testing measures electrical insulation behaviour under defined conditions. CAF testing evaluates susceptibility to conductive filament growth within PCB materials. They assess different electrical reliability risks. Explore GEN3 test systems.

What are mechanical bond testing and acoustic imaging used for?

Bond testing evaluates interconnection strength with suitable mechanical methods. Acoustic imaging examines internal interfaces and can reveal delamination in compatible materials. Neither substitutes for every other inspection or electrical test. Explore bond testing and acoustic imaging.

Does inspection confirm electrical functionality?

No. Inspection identifies specified physical features or defects. Product-specific electrical, in-circuit or functional testing may be needed to verify operation, alongside appropriate process and reliability tests.

Traceability advanced assembly and repair

What is MES and how does it relate to traceability?

A manufacturing execution system manages production activities and records. Traceability links identifiers to relevant manufacturing history. The available machine interfaces and data capture plan determine what information can be connected. Discuss integration requirements.

Is laser marking enough for full traceability?

No. Marking creates an identifier; traceability requires that identifier to be linked to reliable process, material and inspection records. Code readability and verification also matter. Explore Bridge laser marking.

How do die bonding wire bonding and advanced packaging differ?

Die bonding attaches semiconductor dies. Wire bonding forms electrical interconnections. Advanced packaging combines compatible placement, feeding and interconnection processes to build more integrated assemblies. The required technologies depend on the package design. Explore advanced packaging.

What determines manual soldering quality?

Clean and solderable surfaces, suitable solder and flux, effective heat transfer, appropriate tip geometry and operator technique all contribute. Controlled equipment and inspection support repeatability. Explore JBC tools.

How is rework controlled?

Define the removal and replacement process, thermal profile, alignment, board support and inspection criteria. The procedure must protect the PCB and nearby components and meet the product’s acceptance requirements. Explore VJ Electronix rework.

When is component recovery appropriate?

Recovery can be considered for suitable components when condition, traceability and acceptance requirements allow it. Specialist services may include reballing, contact refurbishment, testing and repackaging. Explore Retronix services.
