What is the difference between FPC and Rigid PCB?

Multilayer FPC circuit board

Application: Mobile Phone

Focus on the light weight and thin thickness of the flexible circuit board. It can effectively save the volume of the product, easily connect the battery, the microphone, and the button.

Computer and LCD screen

Utilize the integrated circuit configuration of the flexible circuit board and the thin thickness. Turn the digital signal into a picture and present it through the LCD screen;

CD Walkman

Focusing on the three-dimensional space assembly characteristics and thin thickness of flexible circuit boards, turning the huge CD into a good companion to carry around;

Drive

Whether hard disk or floppy disk, it is very dependent on the high softness of FPC and ultra-thin thickness of 0.1mm to complete the fast reading of data, whether it is PC or NOTEBOOK;

Latest use

Components of a hard disk drive (HDD, hard disk drive) such as a suspension circuit (Suinensi cireuit) and an xe package board.

future development

Based on the vast market of China's FPC, large companies in Japan, the United States, and Taiwan countries and regions have already set up factories in China. By 2012, flexible circuit boards, like rigid circuit boards, have made great progress. However, if a new product follows the "start-development-climax-decline-elimination" rule, FPC is now in the area between the climax and decline. Until no product can replace the flexible board, the flexible board will continue to occupy market share , You must innovate. Only innovation can make it out of this strange circle.

In what ways will FPC continue to innovate in the future?

1. Thickness. FPC thickness must be more flexible and thinner;

2, folding resistance. Bending is an inherent feature of FPC. In the future, FPC must be more resistant to folding and must exceed 10,000 times. Of course, this requires a better substrate;

3. Price. At this stage, the price of FPC is much higher than that of PCB. If the price of FPC goes down, the market will definitely be much wider.

4. Technology level. In order to meet various requirements, the FPC process must be upgraded, and the minimum aperture and minimum line width / space must meet higher requirements.

Therefore, relevant innovation, development and upgrade of FPC are carried out from these four aspects.
