Guide to the PCB Drilling Process
Circuit boards are full of holes and are often referred to as being “swiss cheesed.” While some of the holes are necessary for mounting devices onto the board, most will be used to interconnect the electrical nets between the multiple layers of the PCB. Every one of these holes will have to be drilled for fabrication on the board. A more in-depth look at this PCB drilling process will provide a comprehensive understanding of the process of building a circuit board
