I got one multi-layer board i.e. 4-layer pcb board. I would like to do reverse engineering. But, there is one question, can i interchange the inner layers? That is, change inner layer 2 to inner layer 3 and inner layer 3 to inner layer 2.
What is the problem will happen to my board? For what i know is, inner layer are normally for power and ground plane, nornally. If i interchange it then accually the physical connections are still there. There suppose are no problem to the board. Why some design need the stack up structure in sequence? what i can not interchange them?
Stack Up Structure for 4-Layer board:
top signal ========
inner 2 ++++++++
inner 3 ########
bottom signal --------------
