HOUSE BONDING ADHESIVES
Bonding the lens holder to the substrate requires different adhesive characteristics depending on the type of camera module being assembled. Prostech has excellent bonding capabilities for a variety of substrates, which is critical as the industry incorporates both liquid crystal polymer (LCP) and polyphthalamide (PPA) holder materials.
- For fixed-focus cameras, a traditional thermal-cure, nonconductive house bonding adhesive is the preferred approach.
- More advanced autofocus modules, however, require a different technique – particularly as pixels and lens quantity increase. For this application, active alignment is employed and requires dual-cure adhesives with UV and thermal-cure capabilities.
LENS BONDING ADHESIVES
Lens locking adhesives also play a critical role in the function of the camera module. Effective bonding of the lens barrel to the lens holder requires specialized adhesives that accommodate low-temperature processing.
- Rapid UV cure and high handling strength
- High thixotropic index to reduce liquid migration and unwanted contamination
- Enhance load-bearing and shock-absorbing characteristics
- Deliver the strength, reliability, and performance required
- No high-temperature processing concerns
IR FILTER BONDING ADHESIVES
Bonding of the IR filter to the substrate requires a strong, yet flexible, material to accommodate fast, high-adhesion curing with the ability to absorb stress. Though most substrates are ceramic, substrate materials can vary depending on manufacturing preferences and final product functions.
Because of this, an IR bonding material should:
- Be able to adhere to a variety of substrates
- Excellent UV-cure characteristics
- Accommodate both fixed- and auto-focus module substrate adhesion requirements for exceptional in-field operation
KEY PROPERTIES
- High adhesion to LCP, PA, PPA, etc.
- Low-temperature cure (80°C)
- Faster cure (Improved throughput)
- Dual cure (UV & thermal)
- Low halogen / RoHS-compliant
