FPC Membrane Keyboard

Tiantai electronics custom fpc membrane keyboard will be based on product application, circuit density, conductivity, resistance, whether many electronic components are required, operating environment, customer budget, and whether to pay attention to silver migration. Flexible membrane keyboard assemblies (FPC membrane switch, silver flex membrane switches, and PCB membrane switch). Silver migration usually occurs in Silver Flex Membrane Switches, which is caused by high voltage and humid environments.

Product Description

Tiantai Electronics is a leading China fpc membrane keyboard manufacturer. Compared with traditional membrane switches by using the silver paste printed flex as the circuit layer, the FPC membrane keyboard 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, low electrical resistance value, high conductivity, stable and reliable performance, and FPC membrane keyboard service life longer than an ordinary membrane switch, ability to solder active and passive components into the switch design.

Advantage of FPC Membrane keyboard:

1. Lower electrical resistance and higher conductivity: FPC Membrane Keyboard Copper traces have far lower resistance, only 20% of the silver circuit.

2. Achieve a much finer trace width: With the PET silver circuit, the minimum pitch is 1mm, however, the minimum trace width for copper flex is 0.3mm and the pitch is 0.5mm.

3. Endure High-temperature: The temperature resistance of the flexible printed circuit is better than silver circuitry. FPC can resist high temperatures up to 280 degrees.

4. Ability to withstand bending, creasing, and vibration: FPC can be bent and folded, which improves the efficiency of the configuration and is able to last for a long period of time.

5. SMT technology & smaller designs: When dealing with smaller package sizes, footprints, and rugged environment applications, the Copper Flex circuit can fit more components in a smaller area and can accommodate unique functionality and characteristics in the membrane switch. It is ideal for smaller designs where dense circuit patterns or trace routing limitations exist.

6. Reliability: FPC circuits use a soldered connection that can be up to three times as strong as the conductive glue. Electronics components soldered on FPC are more reliable than those glued on silver circuitry.
