Which performance is better, PVC film panel or pet film panel?
Advantages: ① Strong processing adaptability, different textures can be pressed on its surface to improve the appearance of the material.
②Chemical resistance: Dilute acid, weak alkali, alcohols and alcohol ethers. In addition, PC film has the characteristics of high dielectric strength, non-directionality, high brightness and low fogging degree.
③High temperature resistance (in the temperature range of -30℃~℃) When the temperature or temperature changes suddenly, the change of PC film is not large. ④Good mechanical properties, PC film has high impact resistance and high elasticity, and its yield point force is about /mm2, it is the most impact-resistant plastic application today: PC film is suitable for various signage film panels and other occasions, and the price is moderate, and it is the most commonly used material.
PET (polyester) film
Advantages: PET film has good switch key life and excellent corrosion resistance and wear resistance, and has excellent insulation performance.
Disadvantages: The price is slightly higher than the PC panel, and it cannot resist UV rays.
Application: Instrumentation and home appliance panels with higher requirements.
Is the PC film panel the same as the PC nameplate?
Yes, just one thing, the panel switch.
How to connect the lead tape of the film panel to the printed circuit board
In fact, there is no technical content to replace it. Originally, if you want to touch the contact surface of the machine, you need to stick it directly with glue. Use a wide-point double-sided tape to stick the OK film button panel. How to repair it?
1. Technically speaking, it is very simple to replace the membrane of the keyboard. You only need to use a screwdriver to remove all the screws on the back of the keyboard, and then open the back cover, you can see that the membrane is stuck on the back cover by the pile head. Remove the screw connecting the circuit board, and the membrane can be removed for replacement.
2. Most membrane keyboards are medium and low-grade products, the price is only tens of yuan, and if they are damaged, they will be replaced by the manufacturer. The round-trip shipping cost plus labor and material costs are often higher than buying a new keyboard, thus losing the maintenance value.
