The Difference Between PTH and NPTH in PCB Through-Holes
Introduction Printed Circuit Boards (PCBs) form the foundation of modern electronics, providing both mechanical support and electrical connections for electronic components. Among the most critical features of any PCB are its through-holes—the drilled holes that allow for component mounting and layer interconnection. These through-holes primarily come in two types: Plated Through-Holes (PTH) and Non-Plated Through-Holes…
