High Frequency PCB
This 4-layer High Frequency & HDI PCB is pressed on F4BM+FR4 TG170 and finished at 2.7 mm overall thickness with Immersion Silver over matte black solder mask and white legend. What makes this part non-trivial: Blind Via processing, copper geometry held to 4.0 mil line width and 4.0 mil spacing, mechanical holes from 0.45 mm. 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.
Blind Via runs on our own lines alongside POFV, backdrill, edge plating, plated half holes and step gold finger — no second supplier.
This part is 4-layer; the same presses run 1 to 64 layers, so a stack-up revision does not force a supplier change.
Built on F4BM+FR4 TG170 — RF laminate — drawn from over 120 laminate types held in the warehouse, from KB and ITEQ through Rogers, Isola and Panasonic.
Etched to 4.0 mil width and 4.0 mil spacing here; the process floor is 2/2 mil inner at 1/3 oz copper, with ±10% accuracy on impedance layers.
Finished with Immersion Silver. ENIG 1–3 μin, ENEPIG, hard gold to 3.0 μm, immersion silver, immersion tin, OSP and lead-free HASL are all in-house.
These are the parameters this part was quoted, tooled and shipped against.

Yes. This part is quoted at 4 layers and the plant fabricates 1 to 64 layers, including sequential-lamination HDI up to 5+N(N+M)+5.
It can. F4BM+FR4 TG170 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. Immersion Silver 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.
