UV & Heat Dual-Curing Adhesive AA7700

Mobile camera AA process is a core packaging technology that achieves sub-micron optical alignment by dynamically adjusting the positions of the lens, sensor and other components through real-time image feedback.
It uses UV pre-curing within seconds to lock micron-level accuracy, and low-temperature heat curing to ensure long-term durability.
It combines high bonding strength, low shrinkage and excellent environmental resistance, making it the key material for assembling lens to lens holder, VCM motor and sensor in mobile camera modules.
