PCB stamp hole design

In the design of circuit boards, stamp holes are often used. Their function is to connect the pad and the puzzle. When the pad is used, the hole needs to be metalized, but for the puzzle, only a hole is punched without metalizing the hole. , Whether it is used as a pad or a panel connection, the design can be achieved by placing vias, that is, placing the vias on the edge of the board, and the center of the via is aligned with the edge of the board, and the spacing of the vias can be based on Whether it is used as a pad or a jigsaw for setting, the time for jigsaw is about 1.2 times the aperture. When using the pad, the hole spacing should be set according to the actual pad required interval. Another way to design stamp holes is to directly consult the manufacturer of the printed board. for reference only!
