Fundamentals Friday What is Sheet Resistance? Did you know that the resistance of a square copper PCB trace is the same regardless of the size? Dave explains the theory behind this rather counter-intuitive concept called Sheet Resistance, and demonstrates that it is in fact true. What is the ohms per square of 1oz copper-clad PCB material and how can you use this concept to calculate the resistance of a PCB trace?
