Camera Module Adhesive
What is Camera Module Adhesive?
Camera module adhesive is an adhesive specially developed for bonding components in camera modules. These high-precision adhesives must combine optical clarity, mechanical stability, and thermal resistance without compromising image quality.
Properties of Camera Module Adhesives
- High optical clarity and low refractive index
- Minimal shrinkage to avoid imaging errors
- Precise positioning through controlled curing
- UV and temperature resistance for long-term stability
- Fast initial strength for efficient manufacturing
- Low outgassing for clean optical systems
Applications
- Active Alignment: Precise lens and sensor alignment
- Smartphone cameras: Compact design and high image quality
- Automotive cameras: ADAS systems and backup cameras
- Security cameras: Robust and weather-resistant constructions
Bonding Challenges
