PCB - PCA10040's Stack-up question

[MANGO]

Hi, I use the PCA10040 v1.1.

This is an example of a PCB stack-up.

My questions are,

0. In the case of PCA10040, which is 4 layered, what are the values of height in each layer?

1. I'm creating a custom PCB using the nRF52832-QFAA.

However, due to cost, I'm going to make 2 layered, 1.6mm thick, FR-4 PCB.

The coplanar transmission line won't change even though I choose 2 layered PCB.

However, the height parameter of the stack-up seems to change.

If I create 2 layered PCB, what should be the height value to create a proper PCB?

-Best Regards

I only know the stackup of the nRF51 DK, but I think the stack up will be fairly similar since the design of the nRF5x DKs are close to identical.

The coplanar transmission line on a 2-layer 1.6mm thick, FR-4 PCB should be designed as shown below

Wow. Thanks for the detailed picture. Unfortunately, I don't know how to read Chinese.

What do the Chinese letters mean in English?
