Common problems in PCB Design (4)

Setting of single side pad hole diameter

1, The single side pad usually does not drill. If the hole needs to be marked, its diameter should be designed to be zero. If the value is designed, the hole coordinates will appear when the hole data is generated, and there will be a problem.

2, If single side pad need to drill should be specially marked.

To draw a pad with a filler

The filler pad can be checked by DRC when designing the circuit, but it can not be processed, because this kind of pad can not produce the resistance welding data directly. When the flux is up, the area of the filler block will be covered by the flux, which will lead to the difficulty of welding and installation of the device.
