Multilayer PCB vs Inner layer laminates

Dear danpaul22.chuck,

 

Good day.

This is a courtesy email to let you know that inner layer laminates are to form the inner circuits of the multilayer PCB. They can be divided in 4 groups: 

* double-sided innerlayer laminates etched on one side only 
* double-sided innerlayer laminates etched on both sides 
* double-sided innerlayer laminates with buried via holes 
* innerlayer and outlayer laminate with blind via holes 

The innerlayer laminates are produced in very much the same way as plated-through-holes boards. The main difference is that the innerlayer laminates are very thin and inclined to flexing during manufacturing. 

Thin laminate (base masterial FR-4)

Vendor	Model	Thickness	Copper	TG	ER
SHENGYI	S1141	0.05-3.2 mm	17-105 μm	≥130	≤5.4
SHENGYI	S1170	0.05-3.2 mm	17-105 μm	≥170	≤5.4
ITEQ	IT-140	0.05-1.5 mm	17-175 μm	>135	＜5.4
ITEQ	IT-180	0.05-1.5 mm	17-175 μm	>170	＜5.4
ITEQ	IT-180A	0.05-1.5 mm	17-175 μm	>170	＜5.4

 

If you have requirements on the PCB's, please reply back to this email or following contact by your gerber files and we will get back to you ASAP.
