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
