Choosing a PCB Assembly Partner

Assembly is a service business. The differentiator is not the machine list but what the supplier does before and after the build.

Choosing a PCB Assembly Partner

Review before build

DFM and DFA review before tooling, with a clear answer on what the process can hold.

Sourcing

Whole-BOM purchasing from authorised channels, incoming inspection and life-cycle checks.

Test and records

Test coverage matched to the product, plus lot traceability so a claim can be resolved from records rather than opinion.

After the build

Ask how rework is documented and who investigates field returns. The answer says more about the supplier than a factory tour.

Frequently Asked Questions

  • What should a first meeting with an assembly supplier cover?

    How the engineering review is handled, which parts are sourced in-house, which tests are available and how a defect after shipment is investigated. A supplier that answers with process steps is easier to audit than one that answers with promises.

  • Why does test coverage matter more than price per placement?

    Because a board that fails in the field costs far more than the assembly saving. Test coverage should match the failure modes of the product, and that decision belongs in the quotation, not after the first failure.
