Shenzhen Electronic Assembly and Processing

Electronic connectors do not say millions, hundreds of thousands of species or have, used in various electronic equipment in the field, the manufacturing process is generally divided into: stamping, injection moulding, plating, assembly of four stages. Today's industry practitioners for many years of precision automotive connectors to bring you a detailed understanding of the manufacturing and assembly process of electronic connectors:
1, stamping
Electronic connectors generally start with stamping, through a large high-speed stamping machine will be thin metal strip stamped into terminals, iron shell, pins or copper shell. Large rolls of metal tape into the front of the press, after the mould stamping, winding into the tape wheel, the tape wheel pulls out the metal tape and rolled stamping finished product.
2、 Plating

Electroplating is a particularly important part, it is the terminal, pin contact surface plated with a variety of metal coatings, so that it has excellent electrical conductivity and signal transmission performance and resistance to environmental interference. Electroplating process: first of all, the stamping of good terminals in the cleaning pool to remove dirt, nickel plating, and then plating (tin, gold) and other metals, and then cleaned and dried, and then rolled disc.
3、 Injection moulding

The injection moulding of electronic connectors is generally the plastic material (PA66, resin, LCP) melted and injected into the metal tyre film, and then quickly cooled and moulded. This situation is prone to clogging or missing and other defective products, which requires more inspectors to pick them out.
4、 Assembly

Shenzhen electronic assembly processing, mainly plated pins, rubber shells, copper shells, iron shells, etc. in accordance with the accurate positioning installed together, in order to ensure efficiency is now usually completed by automated machines, such as connector manufacturers Xuan Ye with self-developed assembly machines. Of course, although the machine is highly efficient, high accuracy, but there will inevitably be the case of not installed in place, which will need to be tested by the quality inspection personnel to pick out substandard products.

The above is the manufacturing process of electronic connectors, after the manufacture of products want to sell, but also need to go through the quality inspection, pick out substandard products, and then after the salt spray test, insertion and extraction force test, electrical performance and other testing instruments, and then encapsulated after reaching the standard. The encapsulation method is usually: PE bag, blister disc, PEEL roll, TAPE tube. (According to different connectors, terminals, plastic shells, etc. to choose a different way of packaging)
