Selecting the right printed circuit board (PCB) connector is a critical step in any electronics project. Connectors act as the interface between a PCB and other components, modules, or external systems. While they may appear to be simple hardware elements, connector choices directly affect electrical reliability, mechanical stability, and long-term performance. This guide outlines the key factors for meeting both functional and physical PCB demands.
