Routing Between Adjacent Pads of SMT Components

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

PCB Bends: Are Arc Traces Always the Best Option?

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
