1. Stamping. 2. Plating. 3. Molding. 4. Assembly.
1. Stamping, the manufacturing process of electronic connectors generally starts with stamping the pins. Using a large high-speed stamping machine, the electronic connector (pins) is stamped from a thin metal strip. One end of the large roll of metal strip is fed into the front of the stamping machine, while the other end passes through the hydraulic workbench of the stamping machine.
The metal strip is pulled out by the winding wheel and rolled up to produce the stamped finished product.
2. Plating. After the stamping of the connector pins is completed, they should be sent to the plating section. At this stage, the electronic contact surfaces of the connectors will be coated with various metal layers.
Similar issues to those in the stamping phase, such as twisting, breaking, or deformation of the pins, may also occur during the process of sending the stamped pins to the plating equipment.
3. Molding. The plastic housing of the electronic connector is made during the molding phase. The usual process involves injecting molten plastic into a metal mold and then quickly cooling it to form. Some defects include filling or partial blockage of the insertion holes (these holes must remain clean and unobstructed for proper insertion with the pins during assembly). Since backlighting can easily identify missing or blocked holes in the housing, the machine vision system used for quality inspection after molding is relatively simple and straightforward.
4. Assembly. The stage of manufacturing electronic connectors is the assembly of the finished product. There are two ways to connect the plated pins with the molded housing: single insertion or combined insertion.
Single insertion refers to connecting one pin at a time; combined insertion connects multiple pins to the housing simultaneously. Regardless of the insertion method used, it is required to check all pins for defects and correct positioning during the assembly phase; another routine inspection task is related to measuring the spacing on the connector mating surface.
