ESD Shielding Layer PET Circuit Membrane Switch FPC Keypad With LED

ESD Shielding Layer FPC Membrane Keypad With LED

Everlight 0805 LED welded on the lower FPC circuit layer consists of the membrane keypad with buttons and LED window embossed. The product are mainly used as industrial control keypad, for it's tactile keys and stability of function. Selecting Autotype F150 matte PET to make the overlay appears elegant and colorful. Also, keypad can be customized based on customer's design such as button icons, colors etc. The circuits are printed with Acheson ED-820B silver paste, so that it can be low resistance and function well. Item HW-000614 with strong function is able to weld with colorful LEDs. Besides, the product including electrostatic shielding protect the function from static.

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.
