Background technique

As people's demand for convenient application of electronic products is becoming more and more obvious, it has attracted the continuous attention of various manufacturers. In order to improve the competitiveness of electronic products, manufacturers must continuously strengthen and expand the functions of electronic products. In addition to the light, thin and small appearance, its structure and transmission speed also need to be continuously increased, so as to improve the user's convenience in operation and use.

Since electrical connectors and electronic devices with electrical connectors are used to connect electronic products or between components in electronic products for signal transmission, the importance of electrical connectors and electronic devices with electrical connectors on electronic products is no longer In other words, how manufacturers can easily assemble electrical connectors and electronic devices with electrical connectors during manufacturing, reduce assembly costs, and at the same time take into account the functions of electrical connectors and electronic devices with electrical connectors has become a challenge for various manufacturers. Where manufacturers compete one after another.

Among the electronic connectors, there is also the biggest breakthrough in the USB connector. The USB (Universal Serial Bus) universal serial bus is a serial bus standard for connecting external devices. It is widely used on computers and is the most versatile. Specifications, can also be used on set-top boxes and game consoles, and even many industrial instruments are connected to computers through USB. USB can not only provide data transmission for peripheral devices, but also provide power supply. Portable devices exchange data directly.

From the very beginning, USB was the USB1.0 specification, with a transmission speed of 1.5Mb/s. In 1998, the USB2.0 specification was introduced, and the transmission speed was increased to 12Mb/s. This specification has been widely used in electronic products. Among them, the latest USB3.0 specification has increased the transmission speed to 5.0Gb/s, which is more than 10 times that of the USB2.0 specification. Because the speed is much higher than before, it has become a product that various manufacturers will promote in the future. .

Therefore, with the prospect of USB3.0 specification products in the future, how to achieve the purpose of simple manufacturing of USB3.0 products has become a problem that manufacturers need to overcome. The number of terminals is large, so how to increase the welding strength of USB3.0 electrical connectors and electronic devices with electrical connectors when they are soldered and fixed on the circuit boards of electronic products is also one of the problems that need to be overcome urgently.
