What is the fpc connector and what is the function of the connector!cnwitchip.com

　　In the context of the rapid development of electronic devices represented by smart phones in the direction of miniaturization, as a functional component of circuit boards, FPC connectors, as a major connection plan, have become the internal choice of flexible circuits for current consumer electronics devices to connect circuits One of the main connection schemes of the board is more and more widely used.

　　In the automotive market, FFC/FPC connectors are widely used in GPS devices, LCD monitors, and radio equipment to attract entertainment devices such as DVD players; in the medical field, FFC/FPC connectors can assist with patient monitors Such as miniature devices for handheld devices; in many military and aerospace applications that are based on compact planning, FFC/FPC adapters have also begun to be used in the car market.

　　As far as the current market usage is concerned, FPC connectors are mainly 0.5mm products at this stage, and products with a distance of 0.3mm have also been used in many applications. In short, height and pin distance are two important development directions for fpc connectors in the future, especially the latter. Take the consumer product market as an example. On the one hand, products tend to be miniaturized. On the other hand, many functional modules are continuously integrated into the system, and more and more signals need to be transmitted, which requires more management. With feet, FPC connectors must have more contacts, even smaller distances, and smaller and smaller shapes, and then achieve the goal of high-density integration.

　　The role of 　　 connector:

　　With the trend of integrating LCD drivers into LCD devices, the number of FPC pins will decrease accordingly, and related products have appeared on the market. In the long run, FPC interposers are expected to be integrated in the framework of mobile phones or LCD modules together with other mobile phone components.

　　The basic functions of connector knowledge can be divided into three categories: mechanical function, electrical function and environmental function. Another important mechanical function is the mechanical life of the soldering iron. Mechanical life span is actually a lasting goal, which is called mechanical operation in the national standard GB5095. This method uses one insertion and one extraction as a cycle, and whether the connector can complete the connection function (for example, the contact resistance value) after the regular insertion and removal cycle is used as the criterion.

　　In addition, stability and reliability are still the main practical performance goals of FPC connectors. It requires that in planning, whether it is plastic mold flow, terminal function, positive force, or the cover at the FPC connector, before the product is mass-produced , The planner should use various software to analyze it in detail to confirm whether its strength and structure are reliable. In the manufacturing process of the FPC wiring machine, due to the selection of semi-automatic or even fully automatic assembly, inspection and packaging processes, the amount of red work is reduced, and the quality or other problems that may be caused are greatly reduced.
