What are the film button design raised up.the advantage

Thin-film button bump advantage is what? Want to know? So, the following understand understand together:

Button is raised with pressure drum machine to press the mask layer on the key body area. This method according to the natural properties of the membrane switch and convex concave features, there are strict temperature and pressure requirements. Basic form is as follows: (1) the box line raised: switch edge raised when used. (2) the plane convex: is used when the entire switch above the surface. (3) the ball convex: used for machining spherical buttons. (4) the box line bump + convex ball: not commonly used.

Membrane keyboards raised advantages: (1) enhance the adornment effect of the membrane switch appearance. (2) the operator of the sense of touch is more sensitive. (3) the accurate given the range of the key body. (4) improve the recognition speed.

The design factors to consider:

(1) need a dedicated mold machining.

(2) raised the limit of the polyester temperature 50 ℃.

(3) bump height should be no more than 1.5 times of the thickness of the material.

(4) the plane projection should be at least 3 mm or 5 mm from edge.

(5) the box line raised edge button distance at least 5 mm.

(6) will reduce the mechanical life force (mechanical life should be able to operate for polycarbonate film of face of not less than 100000 times).
