PCB Warpage: Causes, Prevention & Solutions Explained

In PCB manufacturing and assembly, dimensional stability is a critical factor that directly affects product reliability and production yield. One common but often underestimated challenge is PCB warpage. PCB warpage occurs when a circuit board bends, twists, or loses its original flatness due to thermal stress, material characteristics, design imbalance, or manufacturing process variations. Although...
