PCB Design Hole spacing cannot be ignored

In the production of single-sided or double-sided PCBs, the non-conducting holes or conducting holes are directly drilled after blanking; the multi-layer boards are drilled after the pressing board is completed.According to the function, drilling can be divided into: part hole, tool hole, through hole, blind hole, buried hole. Conventional drilling is processed by drilling machinery. …
