Via is one of the important components of multi-layer PCB circuit boards, and the cost of drilling usually accounts for 30% to 40% of the cost of PCB manufacturing. Simply put, every hole on the PCB can be called a via. From the point of view of function, vias can be divided into two categories: One is used as electrical connection between layers The second is to fix or locate the device In terms ...

Why do PCBs need impedance Control? 01 What is Impedance In circuits with resistance, inductance, and capacitance, the resistance to alternating current is called impedance. Impedance is usually represented by Z, which is a complex number. The real part is called resistance, and the imaginary part is called reactance. The blocking effect of capacitance on alternating current in the circuit is call...
