For the layout of SMT components with small pin pitches such as QFP, QFN, and SOP, we sometimes encounter situations where adjacent pins of these components need to be interconnected. It has been observed that many designers, in an effort to save time, directly route the connection between the pads, effectively shorting the pins together. … Read more
Question: In PCB routing, there are three common types of bends: right angle, 45 degrees, and arc (as shown in the figure below). Which type of bend is the best? This question can be answered relatively easily based on experience, with most people agreeing that arc > double 45 degrees > right angle. However, empirical … Read more
Introduction:Everyone knows that impedance should be continuous. However, as Luo Yonghao said, “In life, there are always times when you step in something unpleasant,” PCB design also has its moments of impedance discontinuity. What should we do? Characteristic Impedance Characteristic Impedance: Also known as “Feature Impedance”, it is not a DC resistance, but a concept … Read more
