There are many types of silicone buttons, including single-point silicone buttons, remote control silicone buttons, conductive silicone buttons, light touch silicone buttons, light-transmitting silicone buttons, and patch type silicone buttons. The conductive silicone button is the most common conductive button. But sometimes, the problem of conductive black particles falling off of conductive silica gel buttons occurs. Why is this?
Conductive methods of conductive silicone keys are divided into three types: conductive ink, conductive black particles, and pot slices.
1. The vulcanization temperature is too low.
Solution: The temperature should be too low to cause black particles to fall off.
2. The curing time is too short.
Solution: The vulcanization time is too short, and the conductive adhesive buttons are not fully vulcanized, which will cause black particles to fall.
3. Incomplete exhaust.
Solution: Incomplete exhaust will not only cause wind in the silicone buttons, but also cause black particles to fall.
4. The molding temperature is too high.
Solution: If the molding temperature is too high, it will cause the rubber to be formed during the flow of the mold, which will cause the black particles and the rubber to not be well combined.
5. The conductive black particles are dirty or damp.
Solution: If the conductive black particles of the conductive silicone buttons are improperly stored and are contaminated by dust, oil, or damp, it will affect the bonding of the conductive black particles and the rubber material, causing the black particles to fall off.
6. Too little rubber or too low molding pressure.
Solution: A certain amount of pressure must be applied to the bonding between any two kinds of objects, and this happens to be due to insufficient pressure, which causes the black particles and the rubber material to not be able to bond well.
Seeing this, do you know the reason for the black particles of the conductive silicone button? In the production process, as long as you pay more attention to the occurrence of these problems, avoid this situation, and observe carefully, find and solve the problems in time, you can improve production efficiency and improve product quality.
