Hi Expert,
previously customer is refer to below guide to layout.
customer feedback there is some emi issue, so they want to change the stack-up to below, can you help give some suggestions to us?
May I ask if it is feasible to change the stacking of the lower six layers to 2, 5 for GND layer, 4 for power layer, and 1, 3, and 6 for impedance lines?Due to the lack of a reference ground plane at the top layer in the previous plan (impedance lines 2 and 5, GND lines 3 and 6), the wiring coming out of the SOC terminal will affect the EMI performance
BR,
Biao
