AA process adhesive for mobile phone cameras AA7700

The AA process for mobile phone cameras is a core packaging technology that dynamically adjusts the position of components such as lenses and sensors through real-time image feedback to achieve sub-micron level optical alignment. It uses second-level UV pre-curing to lock in micron-level precision and low-temperature thermal curing to achieve durability. It also takes into account high bonding strength, low shrinkage and excellent environmental resistance. It is the core material for assembling lenses-mounts, VCM motors and sensors in mobile phone camera modules.
