Product Description

Gold-plated metal domes added to the membrane keypad provide the upper circuit layer. That contributes the keys to visual, audible, and tactile feedback. The keypad can performance well in high temperature environment. The product are mainly used as control keyboard for movable electric appliances. Also, keypad of Haiwen can be customized based on customer's design such as button icons, colors etc. Transparent window is manufactured with UV ink. Selecting Autotype F200 matte PET to screen print the overlay appears elegant and colorful. The circuits are made of Acheson ED-820B silver paste, so that it can be low resistance and function well. The rear adhesive is 3M300lse.


Membrane keypad has the advantage of the whole flat, thin shape, quality, small, dust-proof, good, good water resistance, is a semi-enclosed structure. In addition, the panel design, and great freedom of choice of colors. Positive range of applications of desktop computers, copiers, fax machines, toys, square computer, word processor and other areas of expansion.


For the production of membrane keypad substrate of the following:

(1) polycarbonate film

Polycarbonate film great temperature range (-135 ~ 135 ℃), when the temperature or humidity changes, the performance of this material changed little, from 100 to ensure the panel can be various types of equipment under a variety of harsh environment use.

(2) PVC film

Poor heat resistance, especially in high temperature conditions, the softening temperature of 59 ℃, less flexible polycarbonate film good. But it has a high elongation (130%), but also because of its low price, it is suitable for use in the general conditions.

(3) polyester film

Flexibility and heat resistance are good, the price range of between polycarbonate film and PVC film. But its hard to process into films matt type surface texture, often isolated and the transparent sheet, while the vast majority of the surface of polyester film of plastic printing ink can not get satisfactory results, generally requires the use of a particular special ink.

(4) Polyethylene film

Polyethylene film with excellent physical properties and chemical properties, and ability many chemicals, such as alcohols, aliphatic hydrocarbons, aromatic hydrocarbons, esters, ketones and alcohol ether etc. However, the higher the price of polyethylene film.
