What advantages does FPC apply to the mobile phone industry

The number of orders for slide phone boards and folding phone multilayer boards is increasing. How FPC manufacturers control the quality and do a good job of such products in the process is crucial

What are the advantages of FPC

With the miniaturization, high speed and digitalization of electronic products, with the rapid development of personal communication terminals, shanzhai mobile phones and 3G communications and the demand for networking of information terminals (computers, televisions, telephones, faxes), the FPC life and impedance requirements for sliding and folding mobile phones that are suitable for the mobile phone industry at the communication end are increasingly refined, How to control such products in the process is crucial.

FPC (Flexible Printed Circuit, also known as FWPC) has the following characteristics:

(1) Good flexibility: it can bend and deform at will, the winding radius is small, and it can move freely in X, Y, Z directions;

(2) Small occupied space: light and thin, making full use of the narrow space of instruments and meters, meeting the requirements of small and light electronic products;

(3) Light weight: the soft board is designed according to the current carrying capacity rather than the mechanical strength, so it is light;

(4) Good sealing performance: low tension sealing design, can withstand harsh environment;

(5) Stable transmission characteristics: the wire spacing can be freely designed according to electrical parameters, and the general layout is finalized;

(6) Good assembly process: the product has good free termination and overall termination performance, and is suitable for welding, plugging, stereo wiring and three-dimensional space connection;

(7) Good insulation performance: high polymer materials such as base material PI and PET used for soft board have high insulation strength, and general lines are protected by covering film, so the insulation performance is greatly improved.

In recent years, FPC, with its own characteristics, has played an increasingly important role in the PCB design of slide phones and folding phones. People have more and more strict requirements on their life span. Therefore, recently, the number of orders for the multilayered boards of our company's slide mobile phones and folding mobile phones has increased. In order to strengthen the quality and training of personnel, the design and layout concept, material selection, and process maintenance in the production process of the multilayered boards of slide mobile phones and folding mobile phones have been specially controlled to reduce the occurrence of defects and increase the percentage of first pass rate.
