PCB Design Rules

Initially PCBs were designed manually by creating a photomask on a clear mylar sheet, usually at two or four times the true size. Starting from the schematic diagram the component pin pads were laid out on the mylar and then traces were routed to connect the pads. If you have many questions of PCB Design, please come here!

The thick lines of my PCB should be able to pass a high voltage signal through it. The board will be kept inside a enclosed box. I think my boar5d is relatively safe. However, there is still a question: what are some ways to cover up exposed signals?

In situations like that, high voltage traces are exposed when the cover is removed for maintenance I have added a plexiglass cover over the PC board.

If you have arranged all the connections on the bottom side of the board and then mounted the board in the enclosure with the bottom of the board facing to the base of the enclosure then this leaves things about as safe as you can get without excessive other measures.

You don't need to cover anything up.
