Today, someone sent a picture to Lao Wu, asking about the several white translucent substances on the fixed seat of the PCB shown in the image. He didn’t know what they were or why they appeared on the PCB. I looked at the picture and thought it should be hot melt adhesive used for fixing … Read more
Previously, we discussed various aspects of crosstalk, including its sources, formation, types, simulation, and testing methods. We also introduced some methods to reduce crosstalk, one of which is to protect important signal networks with ground networks. This additional ground network is commonly referred to as a guard trace, as shown in the figure below: Can … Read more
