PCBA & electronics
PCBA from prototype to production, tested before it ships.
PCBA and electronics manufacturing from JCH Design & Manufacturing. Component sourcing to a named BOM, SMT and through-hole assembly, functional test, prototype to production through vetted partner factories. Asia cost without the China tariff exposure.
Component sourcing to your named BOM, SMT and through-hole assembly, and functional test on every unit — from a first prototype run to production. Asia manufacturing cost, with the country-of-origin on the right side of the tariff lines.
Why hardware teams come to us
Small runs that behave like big ones.
The gap between a dozen prototypes and real production is where hardware startups get stuck. We bridge it with sourcing discipline and test, not hope.
Named-BOM sourcing
We buy to your exact BOM. Where a part is constrained or end-of-life, we flag it and propose a qualified alternate for your sign-off — no silent substitutions.
Functional test, every unit
Test fixtures and pass/fail criteria defined with you and run on the whole run, so field failures are caught on the bench.
Asia cost, better origin
Assembled at vetted partner factories, your boards carry a country-of-origin that generally sits outside the China Section 301 lists.
Capabilities
From Gerbers to a finished, tested assembly.
Board fabrication, assembly, harnessing, test and final assembly — handled as one run rather than scattered across vendors.
PCB fabrication
Rigid and multi-layer boards fabricated to your stack-up and impedance spec at qualified partner fabs.
SMT & through-hole
Fine-pitch SMT and through-hole assembly, with solder-paste inspection and AOI where the board warrants it.
Functional & in-circuit test
Custom fixtures, functional test and in-circuit test to criteria you approve, logged per unit.
Cable & harness
Wire harnesses, connectors and battery packs built and tested to your drawing.
Conformal coat & potting
Protection for boards that live in heat, vibration or moisture, applied where the environment calls for it.
Box build & final assembly
Board into enclosure, label, firmware load, kit and retail-ready pack — shipped as a finished product.
Materials & construction
Specified once, then held.
Pinned down before sampling, so there is nothing to argue about once a lot is running.

- VolumePrototype runs through production; no silent MOQ games
How it works
From your files to packaged units.
- Send BOM & GerbersBoard files, your named BOM and any test spec. We sign your NDA first.
- Review & sourceWe check manufacturability, flag EOL or constrained parts, and propose alternates for your approval.
- Prototype & testA first run is assembled and functionally tested to prove the build before you commit to volume.
- Scale with testProduction assembled to the same discipline, with functional test logged per unit.
- Box build & shipFinal assembly, firmware load, labeling, kitting and retail-ready pack.
Questions
What buyers ask first.
Can you handle both prototype and production?
Yes — and we build the prototype to the same sourcing and test discipline as production, so scaling up is a volume change rather than a fresh qualification.
How do you handle component sourcing?
We buy to your named BOM. If a part is end-of-life or constrained, we flag it and propose a qualified alternate for your approval — we don’t silently substitute.
What test do you run?
Functional test on every unit to pass/fail criteria we define with you, plus in-circuit test and AOI where the board warrants it. Results are logged per unit.
Can you do box build and final assembly?
Yes — board into enclosure, harnessing, firmware load, labeling, kitting and retail-ready packaging, shipped as a finished product.
What about certifications?
Partner-factory quality certifications are verified and never represented as JCH’s own. We support your compliance testing, but the product certifications are held by you or the named partner, honestly.
