Double Side Ceramic Based Immersion Gold 3u Laser Cutting PCB Board

Ceramic PCB

Double Side Ceramic Based Immersion Gold 3u Laser Cutting PCB Board

This 2-layer Ceramic PCB is pressed on a ceramic base and finished at 1.0 mm overall thickness with ENIG 3u. What makes this part non-trivial: copper geometry held to 4.0 mil line width and 4.5 mil spacing, mechanical holes from 0.25 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.

Ceramic PCB

What matters on this build

2-layer construction, scalable to 64 layers

This part is 2-layer; the same presses run 1 to 64 layers, so a stack-up revision does not force a supplier change.

Ceramic Based laminate

Built on Ceramic Based — ceramic base — drawn from over 120 laminate types held in the warehouse, from KB and ITEQ through Rogers, Isola and Panasonic.

4.0 mil / 4.5 mil line width and spacing

Etched to 4.0 mil width and 4.5 mil spacing here; the process floor is 2/2 mil inner at 1/3 oz copper, with ±10% accuracy on impedance layers.

ENIG 3u surface finish

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.

Hole sizes from 0.25 mm mechanical

Drilling covers 0.15 mm mechanical and 0.076 mm laser holes, backdrill to ±0.1 mm and depth control to 0.05 mm.

Questions engineers ask about this board

Can this design be scaled beyond 2 layers?

Yes. This part is quoted at 2 layers and the plant fabricates 1 to 64 layers, including sequential-lamination HDI up to 5+N(N+M)+5.

Can a different laminate be substituted for Ceramic Based?

It can. Ceramic Based 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.

Is ENIG 3u the only surface finish offered on this board?

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.

What files do you need to quote this part?

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.
