\$\begingroup\$

In PCB design there is some clearance and creepage distances to respect according to the UL 60950 standard for example, I want to know why this distances need to be respected in PCB design, what is the risk in DC circuit if the distances is not respected.

  • \$\begingroup\$ Thanks it seems to be helpful i'll try to search about "electrical breakdown (tracking) properties of an insulating material." \$\endgroup\$

  • \$\begingroup\$ Putting traces too close together runs the risk of creating problems during PCB fabrication. Most PCB layout programs like Eagle, Altium, etc. will generate errors during a Design Rule Check (DRC) that will warn you of violations. \$\endgroup\$

  • \$\begingroup\$ The space required between tracks, or between tracks and pads on a PC board is equivalent to the insulation required on wires in a cable, or run close together. \$\endgroup\$ Nov 6, 2015 at 16:52
