China Colorful scratch-resistant membrane keypad Manufacturer, Supplier, Factory

Compared with traditional membrane switches by using the PET silver paste printed flex as the circuit layer, the one key FPC membrane switch is made from Polyimide copper etched FPC circuits. Copper flex traces are more durable and stable, which are resistant to high temperatures up to 280°C, the circuit has high precision, output spacing of 0.5mm or others, low electrical resistance value, high conductivity, stable and reliable performance, and one key FPC membrane switch service life longer than normally membrane switch, ability to solder many kinds of components into the switch design.

CSI Keyboards uses copper flex circuitry in the majority of our custom keypad designs due to its excellent dielectric strength, thermal stability, chemical resistance and flexibility. Copper flex, also known as Kapton circuits, have become the superior choice over printed silver especially for outdoor applications. A printed silver circuit can be replaced with a copper and polyimide construction with minimal additional cost. Copper flex circuitry construction designs offer a significant advantage over printed silver. Copper Flex membrane switch panels are produced using polyimide (Kapton) as the base material. Copper flex keypad switches are manufactured by laminating a thin sheet of copper to a flexible film substrate. The copper is then chemically etched away, leaving the copper traces. An additional layer of polyimide is laminated to the circuit leaving the gold contacts exposed

Gasket seal A gasket seal is used to protect the conductors against humidity and splashes. When humidity seeps into an unprotected membrane switch, migration and oxidation of the conductors can occur. Bolin recommends adding a seal as a precaution if there is humidity or liquid present. EMI / RFI / ESD Shielding EMI : Electro-magnetic interference RFI : Radio frequency interference ESD : Electro-static discharge An aluminum foil shielding is laminated to the circuit to absorb electro-static discharges. The ground can be connected to the switch cable or be separated as a stand-alone cable. If there are transparent windows on your graphic overlay (LCD display for instance), it is possible to use a clear ITO electrical conductive polyester which will provide the same protection as the aluminum shielding.

As the professional manufacturer, Tiantai Electronics would like to provide you capacitive touch keypad. Capacitive touch keypad is based on the principle of measuring changes in capacity in the presence of a conductive object (e.g. a finger). On this principle, sensors can be created, such as buttons, sliders, switches, touchpads, touch screens, sensors for zooming, and other.
