1. When PCB copper is laid, punch holes in the copper. Some holes are connected by cross wires, and some are not. Why?
2. The holes punched in the copper paving of the pcb can be conductive, so if the double-layer PCB design is done, the upper and lower layers are both paving copper. At this time, if a hole is made, the upper and lower layers will not be damaged. The copper is connected together. At this time, the components connected by the copper are connected together soon, isn't there a short circuit?

Whether there is a cross is mainly the software judges the safety distance, and the cross is automatically laid within the safety distance;
The second question, the same network is naturally connected up and down; if it is not the same network, you will report an error if you put it on it, you have to rebuild it.

Test standard points reserved during design

You still don’t understand how to draw a PCB. Every point has a network. If different networks are connected together, an error will be reported.
