Analysis of FPC Thin Film Switch Key Parts

When examining the essential components of the FPC thin film switch, it is crucial to ensure that the elastic plate of the raised button on the switch panel is positioned accurately. Any deviation in placement can disrupt the functionality of the key, resulting in potential failure.

Color Deviation Issue

One of the primary causes of color deviation in the thin film switch is the ink modulation ratio. Additionally, excessively strict color requirements and a limited color range contribute to this problem. These factors are essential considerations across various industries, as controlling color accuracy can be challenging.

Cost Implications

Maintaining a small color range can significantly impact an enterprise's expenses. The cost of production increases when the color range is limited, leading to higher product costs and unit prices. Ultimately, customers may find it difficult to afford products with inflated prices. Therefore, it is essential to keep the range of colors within a reasonable and manageable scope. Button Position Drum bag, need to open the mold to a suitable position, otherwise it will affect the button aesthetic. Non-stick, in addition to the choice of raw materials, but also to ensure that the prototype looks good. If the prototype has grooves, you need to choose high quality glue. Just pick the right gasket.Membrane panel switch features

(1) good durability, membrane panel switch life can generally reach more than 100 million times, so long service life, because the switch action can only be completed through the elastic membrane vertical movement. The elastic thin film has experienced 1 million times of creep, but because the creep range is very small, only 0.1 ~ 0.3 mm (switch stroke) , the material selection is reasonable, far from reaching the limit of the thin film, therefore, thin-film materials can withstand more than a million lifetimes without deformation. On the other hand, the switch contacts are vertical and wear-resistant, while the screen printed contacts can be thick enough and printed with a layer of conductive carbon on the silver paste contacts to achieve high wear resistance and self-lubrication, the lifetime of Membrane switches is tens of times longer than that of mechanical contact switches.

(2) because of the integral sealing structure of the diaphragm switch, the switch contact is not corroded by harmful gas, is not easy to oxidize, is waterproof and dustproof, is more suitable for all kinds of bad environment, and has good sealing performance.

(3) a compact, lightweight, and rugged membrane panel switch can be assembled into a high-density membrane keyboard, which is a sealed membrane structure consisting of multiple layers of film. The connecting wires and conductors between the switches are completed at one time, the total thickness is 1 ~ 3mm, which reduces the volume, reduces the mass and improves the reliability. Color Rich, beautiful appearance, membrane panel switch according to the user’s design concept in the color design of personality, decorative effect in the performance of beautiful materials, decorative beauty, beautiful process features.

(4) in order to reduce the cost of mechanical and electrical products, traditional mechanical switches need to be welded during installation, even with fixed support. The membrane panel switch is installed as a stick type, only need to peel off the backing paper and stick it firmly on the outside of the machine. The circuit socket can be connected after inserting into the machine socket. Save manpower, save material, reduce the cost of the whole machine.
