What we assemble

Board assembly, done in-house.

We take on small and medium batches — including the mixed orders that many SMT factories avoid because of frequent line changeovers.

SMT assembly

Single and repeat SMT builds with fine-pitch parts, down to 0201 components and 0.5 mm pitch BGA.

Through-hole & hand soldering

Manual insertion and hand soldering for connectors, large and odd-form components.

Rework & touch-up

Rework, repair soldering and touch-up as part of your build.

Wave soldering is available through a qualified external partner when the design requires it.

Component supply

Choose how parts are supplied.

Consigned

You supply the PCBs and components; we handle incoming checks, assembly and testing.

Partial turnkey

You supply key or special parts; we source the remaining components.

Full turnkey

We procure the PCBs and all components against your BOM, then assemble and test.

PCBA questions

Is there a minimum order quantity?

There is generally no fixed minimum. Prototype builds, small and medium batches and repeat production are all evaluated. Setup cost and unit price depend on quantity and complexity.

Do you also manufacture bare PCBs?

We focus on assembly. Bare boards can be purchased as part of a turnkey order; board specifications are reviewed with your files.

How is the lead time calculated?

For PCBA projects using readily available components, procurement and production typically take around 15–20 days. The schedule is confirmed for each project. Development, tooling, special materials and final assembly may need additional time. Urgent requirements can be assessed.
