What is double layer PCB?
A two layer PCB is a type of PCB which has conductive copper layers on both sides of the board.
What are double sided PCBs used for?
Fiber optics;Car dashboards;GPS systems.
Can a PCB have multi layers?
yes, the layers can be more higher per stackup.
What is difference between single sided and double sided PCB?
Double-sided PCBs are the same as single-sided PCBs, but the difference is they have two sided traces with a top and bottom layer.
