membrane keyboard pcb

Product Feature

There is long service life for custom membrane keyboard pcb, because the materials used in it have good insulation, heat resistance, folding resistance and high resilience. In addition, the printing of patterns adopts reverse printing, so that the silk screen pattern will not be damaged. Therefore, the service life of membrane switch keyboard can generally reach more than three years.

Materials used in components of custom membrane keyboard

The overlay is generally made by silk printing exquisite patterns and words on colorless and transparent sheets, such as PET and PC less than 0.25mm. Because the main function of the overlay layer is to mark and press keys, the selected materials must have the characteristics of high transparency, high ink adhesion, high elasticity and anti-folding.

Product Description of membrane keypad keyboard

The main function of the inner adhesive layer is to closely connect the overlay layer with the circuit layer to achieve the effect of sealing and connection. Generally, the thickness of this layer is required to be between 0.02-0.05mm, with high viscosity and anti-aging. In the production, special double-sided adhesive tape for membrane switch panel keyboard is generally selected. Some membrane button keyboard are required to be waterproof and high temperature proof. Therefore, the inner adhesive layer must also use materials of different properties according to needs.
