Why teams choose us
The clock starts at Clear To Build.
Revisions are reconciled before anything is placed, so a fast line never builds the wrong board faster.
Inspection sized to the board.
100% AOI, 100% X-ray on BGAs and full traceability are standard, not add-ons.
Engineers on the floor.
NPI questions go to the people running your build in San Jose. You don’t wait on a ticket queue.

How it works
Six steps from a released package to inspected boards.
Send the build packageBOM, Gerbers, centroid data, drawings, quantities and target date.
Engineering reviewWe check that the BOM, Gerber and placement revisions agree. You get open questions and a quote.
Authorize procurementAfter your PO, we source to your approved manufacturer list.
Clear To BuildMaterial is verified and shortages are reported. The lead time starts here.
AssembleStencil, placement and reflow matched to the board, following the quoted process.
