Multilayer printed circuit board has three or more layers of conductor pattern; the conductor layer has inner layer and outer layer. The inner layer is a conductor pattern completely inside the multilayer board; the outer layer is a conductor pattern on the multilayer board surface. In general, the inner conductor pattern is processed first, then the machining hole and the outer conductor pattern are processed, and the inner and outer layers are connected by metallized holes.
The fabrication process of single sided and double sided PCB is basically similar. The structure and fabrication are relatively simple, but the multilayer circuit board is different, the requirements for structural design and process fabrication are very high, the higher the number of layers is more difficult.
Double sided PCB board is the provider of electronic components, which plays an important role. The PCB circuit board is finished; it needs to be stored to avoid the damage. What is the storage method of double sided PCB? （rigid pcb）
