Frequently Asked Questions

What files do you require for PCB manufacturing?

To start PCB manufacturing, we would require various design files including Gerber Files, Bill of Materials (BOM) file, Assembly drawings, Preliminary files or any other special requirements file.

How long is rigid flex PCB lead time, usually?

The lead time for such boards is 1 to 2 weeks; however, it will depend on the bespoke requirements.

What quality compliance are you providing for rigid-flex circuit boards?

We manufacture rigid flex circuit boards, rigid PCBs and flex PCBs in accordance with UL, ISO-9001, AS 9100, IPC-6012/6013 and MIL performance standards.

What surface finishes do you offer for rigid flex PCBs?

We offer Immersion Ni/Au and OSP. We also provide custom surface finishing or plating for rigid flex circuit boards.

What stiffener material do you use?

We use FR4, steel or aluminum.
