Common problems in Membrane Switch design

Common problems in Membrane Switch design
The keys on the membrane keyboard are very important devices. Different keys are easily distinguished by different colors. In this way, the operating keys can only be recognized by the operator's vision, and there is no information to indicate whether they are within the effective area of the keys, resulting in the user's inability to accurately control the keys, which may affect the use of the whole Membrane Switch.
There are often problems in the design of thin film circuit. The shrapnel in the key needs to be placed properly without offset, otherwise it will affect the control of the key or even lose its function; Color is also a problem that needs to be paid attention to. Ink needs careful modulation proportion, otherwise it is easy to cause color deviation, and the requirements for the range of color are too small. These problems are difficult to control in any industry, so professionals should control them as much as possible. The bulge position of the key needs to be opened to the appropriate position, otherwise it will affect the beauty of the key. The back glue is not sticky. In addition to the selection of raw materials, confirm the shape of the prototype. If the prototype has grooves, it is necessary to select high-quality viscose. The choice of back glue is appropriate.
What determines the quality of Membrane Switch
The same film Membrane Switch, its quality often has many differences. The difference of its quality can be determined from the production personnel, production equipment, product materials, methods and environment. Domestic manufacturers often have great differences in scale and grade, and the implementation of products is also different.
Considering the cost factor, many small manufacturers reduce the cost from raw materials. This makes the produced products often shoddy, and do not meet the requirements of qualified products in terms of service life and quality. However, enough efforts are spent on packaging, so that there is no difference between products and genuine products, which seriously damages the interests of consumers. When purchasing the required products, we must ensure the quality of product materials.
From the perspective of printing, the surface treatment effect of the film is the most important, whether it is affected by moisture. The corona effect has timeliness. If it is placed for a long time, the corona effect may decline too much, which can not meet the requirements of printing; Avoid reversing the printing film surface.
There are many factors affecting the Membrane Switch. Different manufacturers have their own methods on how to grasp the production. The quality control of raw materials is the most important. Therefore, Membrane Switch manufacturing enterprises must control the quality of raw materials persistently and effectively.
