Large Format PCB

4/1/1/4 Thick-Copper 550*550mm CTI600 ( S1600L) 6 Layers HASL Lead-Free PCB

Built as a 6-layer stack on S1600L, this board leaves the line at 3.2 mm thickness under HASL Lead-Free over green solder mask and white legend. The demanding part of this build is Large Format Thick-Copper CTI600 processing, copper geometry held to 9.0 mil line width and 9.0 mil spacing, mechanical holes from 0.5 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.

What matters on this build

Large Format Thick-Copper CTI600

Large Format Thick-Copper CTI600 runs on our own lines alongside POFV, backdrill, edge plating, plated half holes and step gold finger — no second supplier.

6-layer construction, scalable to 64 layers

This part is 6-layer; the same presses run 1 to 64 layers, so a stack-up revision does not force a supplier change.

S1600L laminate

Built on S1600L — low-loss high-speed laminate — drawn from over 120 laminate types held in the warehouse, from KB and ITEQ through Rogers, Isola and Panasonic.

9.0 mil / 9.0 mil line width and spacing

Etched to 9.0 mil width and 9.0 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.

Questions engineers ask about this board

Can this design be scaled beyond 6 layers?

Yes. This part is quoted at 6 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 S1600L?

It can. S1600L 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.
