High Speed PCB

16 Layers TU-872 (DK3.8; DF0.008) HASL Lead-Free High Speed PCB

This 16-layer High Speed PCB is pressed on TUC TU-872 and finished at 2.8 mm overall thickness with HASL Lead-Free over green solder mask and white legend. What makes this part non-trivial: a laminate specified at Dk 3.8 and Df 0.008, copper geometry held to 3.0 mil line width and 3.0 mil spacing, mechanical holes from 0.15 mm. IPC-A-610 E Class II is the workmanship standard, verified by 100% AOI, ICT and FCT testing and thickness to ±10%. This one was quoted for electronics device.

What matters on this build

16-layer construction, scalable to 64 layers

This part is 16-layer; the same presses run 1 to 64 layers, so a stack-up revision does not force a supplier change.

TUC TU-872 laminate

Built on TUC TU-872 — low-loss high-speed laminate — drawn from over 120 laminate types held in the warehouse, from KB and ITEQ through Rogers, Isola and Panasonic.

3.0 mil / 3.0 mil line width and spacing

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.

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 0.15 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 16 layers?

Yes. This part is quoted at 16 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 TUC TU-872?

It can. TUC TU-872 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.
