What does the PCB manufacturing process involve?
PCB manufacture is not a design action, but it is an outsourced activity, which is carried out by a manufacturer. Although PCB fabrication is not a design job, it is performed by strictly adhering to the specifications of users or applications given to the manufacturer. The process of PCB manufacturing involves the transformation of the design of a circuit board into a physical structure. The process is based on the stipulation provided in the design package. This physical manifestation is accomplished through the technique, such as: Imaging : The copper-dressed laminates are brought to the preferred layout. Etching : It involves the elimination of surplus copper from internal layers to expose pads and traces. PCB layer stackup creation : The materials of the board are heated and pressed at high temperatures. Hole drilling : The holes are mounted through the hole broochs and vias Defensive coating integration : It is done to mask the surface or s...
