Winchester's micro-d surface mount connectors feature a rectangular shape with rows of pins or sockets, and they are available in a variety of pin counts and configurations. Surface mount technology (SMT) is used to mount the connectors onto the PCB, which involves soldering the pins or sockets to the copper pads on the board's surface. This allows for a reliable and robust electrical connection that can withstand mechanical stress and vibration. Micro-D surface mount connectors are commonly used in applications such as military and aerospace equipment, medical devices, and industrial automation. They offer a high level of performance in a compact and durable package, making them an ideal choice for many demanding electronic applications.
