Layout and wiring issues that should be noted in PCB design when analog signals/digital signals are mixed
ByGrace December 5, 2024December 5, 2024
The operation of analog circuits depends on continuously changing currents and voltages. The operation of digital circuits depends on the detection of high or low levels at the receiving end according to pre-defined voltage levels or thresholds, which is equivalent to judging the “true” or “false” of the logic state. There is a “gray” area…

How to design the safety spacing of PCB?
ByGrace December 5, 2024December 5, 2024
There are many places in PCB design that need to consider the safety spacing. Here, they are temporarily classified into two categories: one is electrical-related safety spacing, and the other is non-electrical-related safety spacing. Electrical-related safety spacing 1.Spacing between wires In terms of the processing capabilities of mainstream PCB manufacturers, the minimum spacing between wires…
