FPC flexible circuit boards are mainly used in the connection of electronic products, as a signal transmission medium, with high reliability and excellent flexibility. The advantages of FPC flexible circuit boards are high wiring and assembly density, eliminating the need for redundant cable connections; good bendability, high flexibility, and high reliability; small size, light weight, and thin thickness; circuits can be set to increase Wiring layer and flexibility; simple structure, convenient installation and consistent installation.

FPC flexible circuit boards can be classified in different ways. According to their flexibility, they can be divided into flexible circuit boards and rigid-flexible circuit boards; according to the number of layers, they can be divided into single-layer flexible circuit boards, double-layer flexible circuit boards and multi-layer flexible circuit boards. Layer flexible circuit board.

The application fields of FPC flexible circuit boards can be divided into three categories: smart phones, wearable devices, and automotive electronics. The application on smart phones covers battery modules, display modules, touch modules, camera modules, connection modules, etc. A smart phone needs to be equipped with 10-15 FPC flexible circuit boards. With the commercialization of 5G, the development of smart phones to miniaturization and large screens, the rise of folding screen phones, etc., will increase the amount of FPC flexible circuit boards. The demand for FPC flexible circuit boards in the field of smartphones is on the rise.

In the field of wearable devices, FPC flexible circuit boards are the main application materials, and the development of wearable devices will increase the demand for FPC flexible circuit boards.

In the field of automotive electronics, FPC flexible circuit boards can reduce the complexity of the process and are small in size, which can effectively reduce weight and save costs. With the development of automotive electronics, the demand for FPC flexible circuit boards for components such as sensors and central control screens has increased, which has brought a broad space for the application of FPC flexible circuit boards.

The demand for FPC flexible circuit boards in the electronics industry is increasing. One is the excellent characteristics of FPC flexible circuit boards, which are suitable for the ultra-thin requirements of electronic products; the other is the high-frequency and high-speed transmission of circuits. High reliability requirements. Therefore, the market scale of FPC flexible circuit boards in the electronics industry is constantly expanding.

The performance of FPC flexible circuit boards needs to be tested by testing, including appearance testing, electrical performance testing, and environmental performance testing. The basic testing standards include substrate film, cover layer appearance, coating process, connection disc and cover layer deviation, voltage withstand, bending resistance, solder resistance, temperature and humidity resistance, salt spray performance, etc. It is divided into intermediate test and final test. The two tests are qualified only after all the regular performances are up to the standard.

FPC flexible circuit board testing can be achieved with the help of shrapnel micro-needle modules, which is beneficial to improve testing efficiency and reduce production costs. In high-current transmission, the shrapnel micro-needle module can carry up to 50A, and the minimum response value in the small pitch field can reach 0.15mm. Not to mention the stable and reliable connection, and the average service life of more than 20w times, and the adaptability is extremely high.

With the emergence of new electronic products, the market and uses of FPC flexible circuit boards have also expanded, and the upgrading of different types of electronic products will bring more considerable development prospects than traditional markets. The selection of suitable shrapnel microneedle modules for FPC flexible circuit board testing will greatly increase product output and usher in an expansion mode.
