Through-hole assembly

Contract through-hole (THT) assembly

Looking for a reliable partner for contract THT assembly? We deliver through-hole (THT) assembly of electronic components - from prototypes and pilot runs to high-volume production - with selective and wave soldering.

THT (Through-Hole Technology) assembly means inserting component leads into plated holes in the PCB and soldering them from the bottom side. We work in leaded and lead-free technology, to the IPC-A-610 standard. Through-hole assembly is ideal where mechanical strength matters - connectors, transformers and power components.

We combine THT assembly with SMT on a single line, so mixed-technology boards are built in one process. Send your documentation (Gerber, BOM, pick&place) and we will prepare a concrete, no-obligation quote.

Why EAE Elektronik

Benefits of outsourcing THT assembly to EAE Elektronik

You hand us the project and receive finished, tested electronics. We combine through-hole (THT) assembly with SMT, inspection at every stage and engineering advice that lowers production costs.

Fast, no-obligation quote

Send your Gerber and BOM files and we will come back with a concrete THT assembly offer. No costs, no commitment.

Selective and wave soldering

We offer selective and laminar wave soldering, in leaded and lead-free technology - we match the process to your project.

Mixed THT + SMT assembly

We build boards combining through-hole and surface-mount components in one consistent production process.

Traceability of every board

Each PCBA gets a unique serial number with a record of the components used - full batch traceability.

AOI and X-Ray quality control

Solder joints are checked with automated optical inspection and X-Ray - defects are caught before shipping.

End-to-end manufacturing

Conformal coating, component sourcing, testing and EMC - without involving extra subcontractors.

Components tracking

Traceability

We monitor and record production processes. Each electronic board is assigned a unique serial number, and information about the used components is stored in the database.
Traceability

Why EAE Elektronik?

We perform both selective wave soldering and surface mount soldering.
Two waves

For selective soldering

They provide precise soldering of through-hole components.

Traceability

Through-hole components

We register the components used in the production process of each product.

Optimization

We minimize unnecessary costs

Before the project enters production, we consult and suggest optimization changes.

Soldering
Wave soldering and selective soldering

Soldering

After placing through-hole components on the PCBs, they undergo a soldering process using either wave soldering or selective soldering, in either leaded or lead-free technology.

FAQ

Frequently asked questions about THT assembly

Answers to the most common questions about contract THT assembly, through-hole technology and working with EAE Elektronik.

THT (Through-Hole Technology) assembly is through-hole mounting - components with leads are inserted into plated holes in the PCB and soldered from the bottom side. It produces mechanically very strong joints, which is why it is used for connectors, transformers, power capacitors and parts exposed to stress.

In THT assembly through-hole components are mounted in holes in the board, while in SMD (SMT) assembly surface-mount components are soldered directly onto the PCB surface. THT offers greater mechanical strength, SMT higher component density. In practice many boards are mixed designs - we perform both in one process.

We use selective wave and laminar wave soldering, in leaded and lead-free technology. Selective wave lets us precisely solder chosen points on mixed boards, while laminar wave is efficient for classic through-hole assemblies.

Yes. We deliver prototypes and pilot runs as well as high-volume production. At every stage - from design review and component sourcing to assembly and testing - we tailor the process to the customer and batch size.

We inspect at every stage: automated optical inspection (AOI), X-Ray inspection and CCTV monitoring. THT assembly is performed to the IPC-A-610 standard, and every board is covered by full traceability.

We hold IATF 16949:2016 (automotive electronics manufacturing), ISO 9001:2015 and ISO 14001:2015. We are a member of IPC and perform THT assembly to the IPC-A-610 standard.

Yes. We offer SMD/SMT assembly, conformal coating, PCB cleaning, component sourcing, test fixture and programmer development, marking and EMC testing - delivering turnkey electronics without extra subcontractors.
