Flexible PCB Assembly

TL;DR

Flexible PCB assembly combines flex circuit fabrication, SMT placement, connector attach, inspection, and functional test under one controlled workflow.

FlexiPCB supports flex PCB assembly from 1-piece prototypes to production with IPC-A-610 Class 2/3 workmanship and IPC-6013 controlled bare-board fabrication.

Polyimide flex, coverlay openings, ENIG pads, stiffeners, and handling fixtures are reviewed before assembly so bend zones are not damaged by component placement or reflow.

Send Gerbers, BOM, centroid, assembly drawing, test requirements, and target quantity so engineering can quote fabrication and assembly together.

Can you fabricate and assemble the flex PCB in one turnkey order?

Yes. We quote bare flex fabrication, SMT assembly, connector attach, component sourcing, inspection, and functional test as one turnkey flex PCB assembly program. This avoids mismatched coverlay openings, pad finish assumptions, and handling damage that often occur when bare-board fabrication and assembly are split across suppliers.

What standards apply to flexible PCB assembly?

Assembly workmanship is inspected to IPC-A-610 Class 2 or Class 3 based on your drawing, while the bare flexible circuit is controlled against IPC-6013 requirements. We also support IPC-A-600 inspection context, UL material traceability, RoHS/REACH documentation, AOI, X-ray for BGA/QFN, and functional test records when required.

What materials and finishes should I specify before assembly?

Specify the polyimide laminate, coverlay or flexible solder mask, stiffener locations, surface finish such as ENIG or OSP, and any dynamic bend zones. ENIG is common for fine-pitch SMT and connector pads, while polyimide coverlay protects flex areas from solder and mechanical damage. We review these choices before quoting so assembly does not compromise bend reliability.
