Conventional 4-layer PCB. Voltage is DC30V. Questions: 1. What is the safe spacing between vias (through holes) and traces? 2. Where can I find these information? Thank you!
A friend sent it to me. She took the trouble to find someone to translate it and shared it with everyone.Mainly introduces the debugging operations on Stellaris microprocessors.Digital electronics are
I have a 4-electrode conductivity electrode. I use a 1khz 2.5V square wave to excite the electrodes and connect two 470k resistors in series. I first found that the voltage on the electrodes is not sy
