The electrical test requires the component to be connected to an electrical testing machine through wires to measure parameters such as the product's resistance, insulation, and impedance. The air tightness test inserts the airtight connector into the product and inflates and pressurizes the product. When the pressure reaches a certain specified value, the switch valve on the air compressor tooling is closed and a constant pressure state is maintained for a certain period of time. On the automated assembly line, after completing the electrical test and air tightness test, the product also needs to be laser coded to mark the subsequent process of the product.
