From files to finished electronics

PCB & PCBA Manufacturing Process

Eight controlled stages connect engineering inputs to a manufactured, inspected and reviewable output.

Eight-stage system

Every stage has an input, control and output

01
Gerber review
Verify revision, board construction, DFM inputs and missing information.
02
Material preparation
Confirm PCB materials, exact BOM, approved alternates and handling rules.
03
PCB fabrication
Manufacture the approved stack-up and monitor the selected process route.
04
Surface treatment
Apply and verify the specified finish for storage and assembly compatibility.
05
Electrical testing
Screen bare boards for opens and shorts against the agreed plan.
06
PCB assembly
Run SMT, THT, programming and mechanical work defined by the package.
07
Final inspection
Complete the agreed visual, AOI, X-ray and functional checks.
08
Shipment
Release the correct configuration, records, labels and protective packaging.
