QUESTION: 6-LAYER PCB MANUFACTURING STEPS | 20 July, 2015

Hi,

does anybody know the steps for manufacturing a 6-layer PCB?

Let's say we have 1 core and 2 pre-pregs.

Thank you, Enrico Migliore

QUESTION: 6-LAYER PCB MANUFACTURING STEPS | 22 July, 2015

Hi,

I got the answer from edaboard.com

A standard 6-layer stack is using 2 cores.

Manufacturing steps for standard 6-layer are:

1. Etch both (double side) core substrates

2. Assemble, press and cure the complete stack:

- copper foil - prepreg - core 1 - prepreg - core 2 - prepreg - copper foil

3. Drill the package

4. Through-plate

5. Etch outer layers
