According to Prismark, the global output value of FPC(flexible circuit board) reached 9.2 billion US dollars in 2011, accounting for 16.6% of the total PCB share. By 2016, the global output value of flexible PCB is expected to reach USD 13.2 billion, with a compound annual growth rate of 7.5%, making it one of the fastest growing sub-industries in PCB industry, and its share in the total PCB market is further increased to 18.4%. The demand for flexible circuit boards is mainly driven by consumer electronics such as smart phones, tablets and touch products. In addition, FPC is increasingly used in high-end electronic products such as automotive electronics and medical electronics.

As a functional part of flexible circuit board, FPC connector has become one of the main connection schemes for consumer electronic equipment using flexible circuit to connect circuit board under the background of rapid miniaturization of electronic equipment represented by smart phone, and its application has become increasingly popular. In the automotive market, FFC/FPC connectors are widely used in GPS devices, LCD monitors, radio devices, and entertainment devices such as DVD players. In healthcare, FFC/FPC connectors enable miniaturization of handheld devices, including patient monitors; The FFC/FPC connector is also being used in many military and aerospace applications where lightweight, compact designs are the main requirements. In fact, the main advantage of FPC connectors is their ability to efficiently utilize existing space, that is, space on the PCB and space within the enclosure, in addition to saving costs, and driving compact and highly mobile designs, thus being widely used in many electronic device segments. Another advantage of the FPC connector is the ability to interconnect moving and moving parts. For example, the display screen of a digital camera can be pulled out or flexibly adjusted while still maintaining an electrical connection to the camera body. Or the connection between the monitor and the body of a clamshell, slide laptop or mobile phone, etc.

From the market application, FPC connector at the present stage to 0.5mm spacing products, 0.3mm spacing products have also been widely used. In general, height and pin spacing are the two most important development directions of FPC connectors in the future, especially the latter. For example, in the consumer product market, on the one hand, products tend to be small; On the other hand, a large number of functional modules are continuously integrated into the system, and the required signal transmission is also increasing, which requires more pins. FPC connectors are required to have more contacts, even smaller spacing, and more compact appearance, and finally achieve the goal of high-density integration.

In addition, the stability, reliability is still a FPC connector is the most important performance indexes, it requirements in design, plastic mold flow, terminal performance, both in terms of positive force, or the lid of the FPC connector, the product quantity antenatal, designers should be used in a variety of software detailed comprehensive analysis, to determine its strength, structure, Ensure connector quality and design reliability. Secondly, in the FPC connector manufacturing process, due to the use of semi-automatic or even automatic assembly, testing and packaging process, manual operation is reduced, thus greatly reducing the possible quality or other problems.
