 Flexible Membrane Keyboards/ Flexible KeypadsÂ

A membrane switch is an electrical switch for turning a circuit on and off. It differs from a mechanical switch, which is usually made of copper and plastic parts: a membrane switch is a circuit printed on PET or ITO. The ink used for screen printing is usually copper /silver / graphite filled and therefore conductive.
 Membrane switches are user-equipment interface utilities that allow for the communication of commands from users to electronic devices. Membrane switches can be thought of as one category of interface utilities alongside touch screens, plastic keyboards, toggle switches and many other kinds of control systems. Interface utilities can be as simple as tactile switches for controlling lighting, and they can be as complicated as membrane keyboards and switch panels for use with computers.

 SMT Stencil / Steel Braided Technical Specifications:
Material thickness 30-600 microns.
Max. Cutting Area 600 x 700 mm (23.6 x 23.6 inch)
Max. Sheet Size 850 x 800 mm (33.5 x 31.5 inch)
Resolution 0.5 microns.

ELEKTROLYTIC POLISHING:
   By a specific electro-chemical process, the smoothness of cutting walls is provided to be smaller then one micron. The smooth surfacemakes seperation of cream solder and stencil easier. Through this process, sieve cleaning period, which is need during the production, is significantly lengthened.
   Also with this process, the micro-burrs, which are occured during the cutting, are cleaned. As a result, quality of printing is increased and a smooth, shiny and easy clean surface is provided.
