Rigid-Flex PCB
This 16-layer Rigid-Flex PCB is pressed on FR4 IT180A and finished at 2.8 mm overall thickness with ENIG 3u over blue solder mask and white legend. What makes this part non-trivial: copper geometry held to 3.0 mil line width and 3.0 mil spacing, mechanical holes from 0.15 mm, finished copper at ½ oz / 1 oz. Quality release covers 100% AOI, ICT and FCT testing, IPC-A-610 E Class II and thickness to ±10%. This one was quoted for electronic device.
Quotation within 6 hours. Gerber, PowerPCB, CAD, AutoCAD, OrCAD, P-CAD, CAM-350 and CAM2000 files accepted.
This part is 16-layer; the same presses run 1 to 64 layers, so a stack-up revision does not force a supplier change.
Built on FR4 IT180A — FR4 — drawn from over 120 laminate types held in the warehouse, from KB and ITEQ through Rogers, Isola and Panasonic.
Etched to 3.0 mil width and 3.0 mil spacing here; the process floor is 2/2 mil inner at 1/3 oz copper, with ±10% accuracy on impedance layers.
Finished with ENIG 3u. ENIG 1–3 μin, ENEPIG, hard gold to 3.0 μm, immersion silver, immersion tin, OSP and lead-free HASL are all in-house.
Drilling covers 0.15 mm mechanical and 0.076 mm laser holes, backdrill to ±0.1 mm and depth control to 0.05 mm.
These are the parameters this part was quoted, tooled and shipped against.

Yes. This part is quoted at 16 layers and the plant fabricates 1 to 64 layers, including sequential-lamination HDI up to 5+N(N+M)+5.
It can. FR4 IT180A is what this part is built on, but material is a design input — Rogers, Arlon, Taconic, Isola, Nelco, Panasonic, TUC, ITEQ, SYTech, Ventec and KB grades are all stocked, and customer-supplied stock is accepted.
No. ENIG 3u is specified here; ENIG at 1–3 μin gold, ENEPIG, hard gold to 3.0 μm, immersion silver, immersion tin, OSP and lead-free HASL are alternatives, subject to panel size limits on HASL.
Gerber RS-274X plus a drill file and a stack-up or impedance note. PowerPCB, CAD, AutoCAD, OrCAD, P-CAD, CAM-350 and CAM2000 formats are also accepted. Quotation normally comes back within 6 hours.
