- GAP control adhesive containing uniform particles
Thermosetting adhesive containing ultra high precision spacer particles
1. Characteristics
1The thickness of the adhesive can be precisely controlled
2Effectively maintain the adhesive insulation
3It is conductive to ensure the consistency of adhesive force
2. Applications
- Inductors, power supply modules, etc.
Expected effect: stabilization of inductance - Pressure sensor and fixing chip of acceleration sensor
Expected effect: increase the sensor sensitivity - Fixing components in the camera module
Expected effect: Suppression of camera sensor shake
