High Frequency PCB
Built as a 4-layer stack on RT/Duroid 5880, this board leaves the line at 1.6 mm thickness under ENIG 1u over green solder mask and white legend. The demanding part of this build is a laminate specified at Dk 2.2 and Df 0.001, copper geometry held to 3.5 mil line width and 3.5 mil spacing, mechanical holes from 0.25 mm. The board is signed off to IPC-A-610 E Class II on outline by Rout / V-cut / Bridge / Stamp Hole and thickness to ±10%. Typical end use is electronic device.
Quotation within 6 hours. Gerber, PowerPCB, CAD, AutoCAD, OrCAD, P-CAD, CAM-350 and CAM2000 files accepted.
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 RT/Duroid 5880 — engineered laminate — drawn from over 120 laminate types held in the warehouse, from KB and ITEQ through Rogers, Isola and Panasonic.
Etched to 3.5 mil width and 3.5 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 1u. 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.

It can. RT/Duroid 5880 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.
