Membrane switches with FPC circuit:
Nice appearance and good tightness
Material: Autotype PET, textured PC, Gloss PC with matte finish,
PVC
Connector: Nicomatic, FCI, Molex, Zif connector,CJT
Customized designs are accepted
Description:
1. Cover film protection film (Cover Film)
Cover film protection film: surface insulation. The common
thickness 1mil with 1/2mil.
Glue (adhesive): thickness according to customer requirements.
Adhesive buildup of foreign matter before pressing the shape from
the paper: avoid; easy job.
2. 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.
3. 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
Performance indicators:
