When going from two to four layer pcb?, Will there be any pitfalls?
I have some two layer boards, but I want to design more layers pcb now. Can you suggest any pitfalls to be aware of for my first attempt, the price of four layers is more expensive than 2 layers,so I'm hoping to not waste the 2 layers pcb.
For combining the 2 layer boards to 4 layer boards, you need to consider the stack-up carefully.
