Large Format PCB

1200mm Ultra-Long Large Format Double Side HASL Lead-Free FR4 PCB

Built as a 2-layer stack on FR4, this board leaves the line at 0.4 mm thickness under HASL Lead-Free over white solder mask and black legend. The demanding part of this build is copper geometry held to 16.5 mil line width and 15.0 mil spacing, mechanical holes from 0.36 mm, finished copper at ½ oz / 1 oz. Every panel is released on 100% AOI, ICT and FCT testing to IPC-A-610 E Class II, holding outline by Rout / V-cut / Bridge / Stamp Hole. Typical end use is electronic device.

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.

FR4 laminate

Built on FR4 — FR4 — drawn from over 120 laminate types held in the warehouse, from KB and ITEQ through Rogers, Isola and Panasonic.

16.5 mil / 15.0 mil line width and spacing

Etched to 16.5 mil width and 15.0 mil spacing here; the process floor is 2/2 mil inner at 1/3 oz copper, with ±10% accuracy on impedance layers.

HASL Lead-Free surface finish

Finished with HASL Lead-Free. 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 0.36 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 FR4?

It can. FR4 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 HASL Lead-Free the only surface finish offered on this board?

No. HASL Lead-Free 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.
