Applications:

1. The mobile phone

Focuses on the flexible circuit board light weight and thin thickness. Can effectively save the volume of products, easy connection of the battery, microphone, and buttons and into one.

2. Computer and LCD screen

Use the one line configuration of flexible circuit boards, and thin thickness. The digital signal into the picture, through the LCD screen

3. CD player

Focuses on three dimensional assembly characteristics of flexible circuit boards and thin thickness. The huge CD to carry around

4. Disk drives

Regardless of the hard disk, or diskette, is very dependent on FPC high softness and thickness of the 0.1 mm slim, read data finish quickly. Either a PC or NOTEBOOK.

5. The latest applications

Hard disk drives (HDDS, hard disk drive) of suspended circuit (Su ensi. N cireuit) and the components of xe packaging board, etc
