pogo pin is a precision connector used in mobile phones and other electronic products, widely used in In semiconductor equipment, it plays a role in connection. There are different appearances according to different applications, but the overall pogo pin There is a precision spring structure inside. The surface of the product is generally gold-plated, and the spring should also be gold-plated when the process is required.

　　 With the continuous development and progress of electronic technology, pogo pin connector products are also developing in the direction of small size, narrow pitch, and multi-function. In addition, the direction of surface mounting, composite and embedded is also pogo A future development direction of pin connectors. The size and shape of the connector are getting smaller and smaller, and the miniaturization of electronic products also puts forward the need for miniaturization for matching connectors, such as portable handheld digital products such as mobile phones that require relatively high connector miniaturization. Generally speaking, there is no way to change the number of contacts and the specifications of the original connectors. If the user needs to change the number of contacts and the specifications of the contacts, other connectors need to be replaced, and the modularized connector The emergence of technology has solved this problem to a large extent.

　　Due to the rapid development of the market, the continuous acceleration of connector technology innovation has prompted pogo The design level and processing methods of pin connectors have also been improved. According to industry experts, semiconductor chip technology is gradually becoming the technical driving force for the development of connectors at all levels of interconnection. For example, with the rapid development of 0.5mm-pitch chip packaging to 0.25mm pitch, level I interconnection and level II interconnection The number of connected device pins ranges from hundreds to thousands of lines.

　　In recent years, fiber optic connectors, USB2.0 high-speed connectors, wired broadband connectors, and fine-pitch connectors have been widely used in various portable/wireless electronic devices. Therefore, the market application hot spots of the connector are also changing accordingly. The process of electronicization of global enterprises and markets is very fast. In the financial crisis environment, the Chinese government has invested heavily in three networks, smart grids, automobiles, and rail transit. It can be seen from the market’s high-speed interconnection of connectors. The demand for current resistance is also getting higher and higher; for consumer electronics, connectors are related to the use of many antennas, and TV system manufacturers require antennas to be installed within a small distance.
