Backed by Combinator

We build circuit boards fast.

One team sources every part, manages fabrication through qualified domestic or overseas partners, then assembles and tests your boards in the US. Fully domestic builds are available when required.

No account required. Review scope, price, and ship date before approval.

Source & verify

We buy every part against your BOM and verify it before the build starts.

Phase 02Day 2–5

Fabricate & assemble

We run fab and assembly with vetted partners we manage ourselves, fully domestic when you need it.

Phase 03Day 5–7

Test & ship

We test every board and ship it with a full quality record.

Common questions

Standard turns run seven days; five at the quickest. Your quote shows the exact ship date before you commit.

Then we build the other way: a longer turn at a lower price. You pick the tradeoff on every order.

No. We start from your last revision, so later revs come back faster.

Full Accountability

One team owns the whole build.

ProvenMetal sets the build plan, manages each facility, and remains accountable from the first sourcing decision through final test and delivery.

Parts stay controlled.

Sourced or consigned, parts are received against the BOM, kept lot-traceable, and handled under MSL and ESD controls.

Testing is planned up front.

Acceptance criteria and fixtures are agreed before production and available at the test site, so failures can be reworked before shipment.

One team owns the outcome.

We manage sourcing, fabrication, assembly, inspection, test, and delivery, then ship the build record with your boards.

How It Works

One partner, start to finish.

[01]

SOURCE

Send your files. We source and verify every part to fit your spec and budget.

[02]

BUILD

We run fabrication and assembly across vetted partners, fully domestic if you need it, and manage the whole build.

[03]

VERIFY

AOI and X-ray on every board, plus functional test, bring-up, and firmware loading when you need it. Full quality record ships with the order.
