Surface Mount Technology (SMT) has revolutionized the design and manufacturing of printed circuit boards (PCBs), enabling more compact, efficient, and high-performance electronic devices. At the heart of SMT’s success are SMT PCB pads, which serve as the critical interface between surface mount devi
Surface Mount Technology (SMT) is a widely used method for assembling electronic components onto Printed Circuit Boards (PCBs). Despite its efficiency and high component density, SMT can sometimes result in defects, one of which is the formation of dull joints. Dull joints, often associated with col
