Reference Design of CRD-22AD12N: layer stackup of the main PCB

gkim

Hello,

With respect to the reference design of CRD-22AD12N, we are going to build the main board by using the PCB design file of MAIN_BOARD-V2.brd.

With respect to the reference layer stackup of the main PCB, I have found out that the prepreg thickneess is 4.42 mils and the core thickness is 59.39 mils.

Meanwhile our PCB manufacturer employs the prepreg thickness of 11.9mils and the core thickness of 43.3mils as a default standard.

Would it be fine if the main PCB is manufactured with the the prepreg thickness of 11.9mils and the core thickness of 43.3mils?

Thank you for your consideration.

With regards,

GKIM

Hi GKIM,

43.3mil is ok if you didn't change the total thickness of PCB.
