HDI PCB
A 8-layer High Speed & HDI PCB built on ISOLA FR408HR, profiled to 1.6 mm finished thickness and plated with ENIG 1u over blue solder mask and white legend. The process window is set by a 1+N+1 sequential-lamination structure, Buried Capacitance processing, copper geometry held to 3.0 mil line width and 3.0 mil spacing. Nothing leaves without 100% AOI, ICT and FCT testing; IPC-A-610 E Class II governs workmanship and outline by Rout / V-cut / Bridge / Stamp Hole is logged. It is specified for electronic device builds.
Quotation within 6 hours. Gerber, PowerPCB, CAD, AutoCAD, OrCAD, P-CAD, CAM-350 and CAM2000 files accepted.
The 1+N+1 build needs sequential lamination and laser via formation; our window runs to 5+N(N+M)+5 with 1.6/1.6 mil trace.
Buried Capacitance runs on our own lines alongside POFV, backdrill, edge plating, plated half holes and step gold finger — no second supplier.
This part is 8-layer; the same presses run 1 to 64 layers, so a stack-up revision does not force a supplier change.
Built on ISOLA FR408HR — low-loss high-speed laminate — 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.
These are the parameters this part was quoted, tooled and shipped against.

Yes. This part is quoted at 8 layers and the plant fabricates 1 to 64 layers, including sequential-lamination HDI up to 5+N(N+M)+5.
It can. ISOLA FR408HR 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 1u 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.
