Guangjiayuan Technology Co., Ltd. is a manufacturer that integrates the research and development, production, and sales of various types of USB connectors. It can produce various types of USB connectors. Below, I will delve into the company's production line and reveal the production process of various connectors for you.

There are various types of USB connectors, and the manufacturing process is basically the same. Generally, they can be divided into the following four processes: stamping, electroplating, injection molding, assembly, testing, and warehousing.

1. Stamping includes stamping the outer shell and stamping the USB terminal. The terminal is the core component of the USB connector and the part in contact with the USB male or female seat. The quality of the terminal material directly affects the performance parameters of the finished product. Our products are generally made of high-quality phosphor bronze, and type-c connectors used on smart phones are usually made of Phosphor bronze or high conductivity copper. The terminals of USB connectors are usually stamped with thin copper strips. One end of the large roll of copper strip is fed into the front end of the high-speed stamping machine, and the other end passes through the hydraulic workbench of the stamping machine and is wrapped in a coiling wheel. The coiling wheel pulls out the copper strip and rolls it up to produce the finished product.

2. After the stamping of the electroplating terminal is completed, the electroplating section will proceed. During the electroplating stage, various metal coatings will be applied to the contact surfaces or shells of various connectors based on the type and purpose of the product. For example, in order to improve the solderability of terminals, they can be coated with a solder layer; In order to improve the conductivity of the terminal USB connector, gold plating is applied to the top of the terminal; In order to improve the corrosion resistance of the USB interface, we can plating it with nickel layers of different thicknesses.

3. The injection molding of the rubber core of a USB connector is the process of injecting high-temperature melted PBT or LCP plastic into a metal matrix, and then rapidly cooling and forming it. During this process, there may be a situation where the melted rubber core plastic fails to fully fill the tire film, which is a typical defect that needs to be detected during the injection molding stage. Other defects include the filling or partial blockage of the socket (these sockets must be kept clean and unobstructed in order to properly connect with the pins during final assembly).

4. The final process of assembling USB connectors is assembly. The company employees continuously and quickly assemble the semi-finished products produced by the above processes using high-speed assembly terminal machines to form one finished product after another.

5. Next, our quality control siege engineers will use various quality inspection systems to detect and control various possible defects that may occur during the four production processes mentioned above. Perform limit detection verification on their performance in various ways. Finally, packaging and warehousing will be carried out.

At present, the USB connector market continues to rise driven by strong demand for consumer electronic products such as gaming consoles, MP3 players, mobile phones, IXDTVs, and digital cameras; In the international market, the top ten connector manufacturers in the world have always been occupied by manufacturers in the United States, Japan, France and Taiwan, China. From the perspective of competition pattern, TE Connectivity, Amphenol, Molex and other three foreign-funded enterprises occupy nearly 80% of the market space of China's mobile communication terminals and micro precision connectors for digital products; However, in order to fully realize market-oriented competition, the connector industry in China has more than 1000 connector manufacturers in Chinese Mainland.
