PCB Tech - Advantages of FPC used in mobile phone industry

As early as a few years ago, by virtue of its own characteristics, FPC played an increasingly important role in the design of slide phones and foldable phones.

The number of orders for sliding cover mobile phone panels and folding mobile phone multilayer boards is increasing. How to control the quality of FPC manufacturers is very important in the process.

What are the advantages of FPC

With the miniaturization, high-speed, and digitization of electronic products, the rapid development of personal communication terminals, copycat mobile phones, and 3G communications and the demand for networked intelligence information terminals (computers, TVs, telephones, and faxes) are suitable for communication terminal mobile phones. The FPC life and impedance requirements required in the industry's sliding mobile phones and foldable mobile phones are becoming more and more refined. However, among manufacturers of FPCs, how to control and do such products in the process is of vital importance.

FPC (Flexible Printed Circuit, flexible printed circuit board, also called FWPC) has the following characteristics:

(1) Good flexibility: it can be bent and deformed at will, the coiling radius is small, and it can move freely in the three directions of X, Y, and Z;

(2) Small footprint: both light and thin, make full use of the narrow space of instruments and meters, and meet the requirements of miniaturization and lightness of electronic products;

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

(4) Good sealing performance: adopts low tension sealing design, which can withstand harsh environments;

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

(6) Good assembly processability: product free termination and overall termination performance is good, suitable for welding, plug-in, and three-dimensional wiring and three-dimensional space connection, etc.;

(7) Good insulation performance: The base material PI and PET used in the flexible board have high insulation strength, and the general circuit is protected by a cover film, so the insulation performance is greatly improved.

In recent years, with its own characteristics, FPC has played an increasingly important role in the design of slide phones and foldable phones. People's requirements for their lifespan are becoming more and more stringent. For this reason, our company has recently increased the number of orders for sliding cover mobile phone panels and folding mobile phone multilayer boards. In order to strengthen the quality and training of personnel, we specially focus on the design and layout concept, material selection and During the production process, process maintenance and other aspects are controlled to reduce the occurrence of defects and increase the percentage of the first pass rate.
