PCB production process: addition or subtraction?
Addition or subtraction? The comparison of three PCB production processes and the initial exploration of similar carrier board technology are as follows: The process of PCB products (including IC carrier boards) mainly includes subtractive process (Subtractive), full additive process (Full Additive Process, FAP) and modified semi additive process (Modified Semi Additive Process, mSAP). 1.Introduction to…
