When choosing a WAFER connector, it is necessary to consider multiple dimensions such as product application scenarios, electrical performance, structural form, material technology, and usage environment. Whether it is board to board or wire to board connection, the voltage, current, signal type, and insertion frequency carried by the connector should be clearly defined. The pin spacing (such as 1.0m, 1.25m, 2.0m, etc.), number of pins, installation method (SMT or DIP), insertion direction, and whether a locking structure is required should be reasonably selected. At the same time, attention should be paid to the material performance of the connector, ensuring that the plastic part meets the flame retardant level, has low terminal contact resistance, long insertion and extraction life, and complies with environmental standards such as ROHS. For different application industries, such as industrial equipment, automotive electronics, or consumer products, attention should also be paid to structural compatibility such as vibration resistance, temperature resistance, and spatial layout. To ensure accurate and reliable selection, it is recommended to adopt a process of “preliminary screening, sample testing, small batch trial production, and final verification”, combined with structural and electrical performance testing and supplier evaluation, to comprehensively reduce design risks. A high-quality and suitable connector not only determines the stability of the overall performance, but also relates to the assembly efficiency, delivery cycle, and customer experience of the product. Therefore, scientific and systematic selection logic has become one of the essential core competencies for hardware engineers.
