High-polymer film of consumption is generally used on TFT-LCD Module and PDP Module process.
Especially, it used in ACF - Bonding process( OLB, TAP Solder Process :Process Drive IC is attached on Glass panel by heating and pressing tool of ACF-Bonding machine ) of TFT-LCD Module, film’s function is shock-absorber of bonding tool and protecting glass panel from glass panel breaking damage cause by particle and unbalance of PCB size.
PTFE skived-Teflon Film is used by itself, other three kind of film is used same time by three of layer.
Teflon Film and other three kind of film’s function is same.
Now our R&D team is continuously developing new film which can used by itself and replace function of three kind of film.

1. PTFE skived Teflon film (SK-TF)

Molded with PTFE into blocks and skived in a length and thickness.
Features include electric property, non-stickiness and moisture repellence.
Suitable for electric insulation with low coefficient of friction.

PTFE skived film function is shock-absorber of bonding tool and protecting glass panel from glass panel breaking damage cause by particle and unbalance of PCB size.
Especially PTFE skived-Teflon Film is usually used on OLB process of LCD Module.
We can manufacture film thickness 0.05mm, 0.08mm, 0.15mm, 0.3mm and going to develop 0.03mm film by our R&D team.

 

2. PTFE coating and dispersion Glass cloth(SK-GF)

1. By using special process of dispersion, PTFE dispersion glass cloth made of thin glass cloth and PTFE.
   It has following characteristics; stable at high temperature, low-friction, easy disassemble, chemical resistance, powerful insulation.
   
2. Due to excellent characteristics, it is widely used on the following purpose;
   - Easy separation of products from belts and fabrics without sticking
   - It reduces friction, endures high temperature, and has chemical resistance.
   
3. Depend on the purpose and applications, PTFE dispersion glass cloth can be supplied to customers with special width and length. We are also suppling electric conducting glass cloth to remove static properties.

PTFE coated Glass cloth use for the release of ACF adhesive and Silicone Rubber in ACF-Bonding process.
(Because we do PTFE coated on Glass fabric mesh, so it has a good release)
We can manufacture product thickness from 0.045mm to customer requirement thickness.

3. Polyimide Film (SK-PF)

Polyimide film and polyimide-fluoropolymer compounded film have excellent high temperature and radiation resistance, perfect electrical insulating properties, good adherence, and chemical resistance.
Polyimide film can be used in temperature from -269 to 400°C for a long span.
Fluoropolymer compound film has self-bonding propertise.
Both can be used in flexible printed circuits and as insulating materials of flat electric cables, electromagnetic wires and motors.
It is widely used in space navigation, electrical motors, transporting machines, weapons, mobiles, electronic instruments, communication equipment and in petrochemical industry.

4. Silicone rubber (SK-SR)

4-1. TFT-LCD Part

This material is used specifically for the assembly of TFT-LCD module.
It works as an electric - conductive medium when the electrode thermal connector of crystal panel is assembled with flexible printed circuit board.
It should uniformly distribute heat and pressure between the heating tool and the connector so that it should not cause any damage to PCB either by heat or pressure during the assembling process.

1. With its high thermal conductivity and superior softness originated from silicone,
   it gives a fast and uniform heat transfer with no damage to PCB.
   
2. It is of excellent property resisting against heat.
   
3. It also has high restoration force and non-sticky properties.

This Silicone Rubber film function is shock-absorber of bonding tool and protecting glass panel from glass panel breaking damage cause by particle and unbalance of PCB size.
