Description:

1. Copper foil substrate (Copper Film)
Copper foil: basically divided into two kinds of electrolytic copper and rolled copper common thickness 1oz 1/2oz and 1/3 oz
Substrate film: a common thickness of the 1mil with 1/2mil two kinds.
Glue (adhesive): thickness according to customer requirements.

2.In need of special light sources (eg: no shadows, no dizzying,brightness uniformity and neon effect ......),

in with the environment needs (eg: a narrow space, complex shapes, temperature and power consumption

constraints, vibration under the environment ......), the illusion is impossible to make up the traditional cold

light source.
In addition, for printed mark, instructions, election propaganda, body decoration and interior design, photo

or text on backlit transparent advertising material, EL cold light is the best light materials

3. Stiffener (PI Stiffener Film)
Stiffener: reinforcing the mechanical strength of the FPC, to facilitate the surface mounting job. Common thickness 3mil to 9mil.
Shape from the paper: to avoid foreign matter adhesive buildup Crimping before the.

4. EMI: electromagnetic shielding film, the protection circuit board line without interference from the outside world (a strong electromagnetic District or susceptible to interference zone).


Applications:
1. 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.
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. 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.

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
