High-temperature resistant button switch for PET yellow PI adhesive material pot ear slices

1. The high-temperature resistant yellow PI adhesive material is an excellent material for applications requiring high-temperature environments. Its exceptional heat resistance allows it to maintain stable physical and chemical properties even under high-temperature conditions, ensuring effectiveness and reliability in various high-temperature processes.

2. The primary component of yellow PI adhesive material is polyimide (PI), which possesses outstanding insulation, wear resistance, and acid and alkali resistance. Through special processing, the PI adhesive material can withstand temperatures up to 300 degrees Celsius and can be used for extended periods at 180 degrees Celsius. Additionally, this material exhibits excellent electrical properties, abrasion resistance, tear resistance, and other characteristics.

3. In applications, the high-temperature resistant yellow PI adhesive material is extensively used for solder masking, high-temperature insulation bundling of transformer coils, insulation materials for capacitors, and other purposes. Particularly in the field of electronics and electrical engineering, it can be applied for high-temperature spray shielding protection of PCB gold fingers, as well as processes such as wave soldering and reflow soldering, to protect electronic components from high-temperature damage.

4. The Metal Dome Array, employing this high-temperature resistant PI adhesive, is primarily used for customer convenience. It allows the Metal Dome Array buttons to be conveniently applied to the PCB during secondary reflow soldering processes. The high-temperature resistance of the PI adhesive ensures that it remains intact without peeling or wrinkling during the process.
