One-stop PCB manufacturing: From metal core to flex and ceramic
- review your Gerber files and stack-up proposals,
- check that line/space, hole sizes, materials and finishes match our process capabilities,
- suggest material and stack-up options for better thermal and electrical performance, and
- consolidate different PCB types into one manufacturing and logistics solution.
