      The Difficulty Of Multilayer PCB Board Prototyping 1. The difficulty of interlayer alignment Because of the many layers of multilayer PCB board, the calibration requirement of PCB layer is higher and higher. Typically, alignment tolerance between layers is controlled at 75um. It is more difficult to control the alignment of multilayer PCB board because of the large size of the unit, the high temperature and humidity in the graphics conversion workshop, the dislocation overlap caused by t...
