This company recently introduced active alignment (AA) adhesives designed for camera module assembly at IPC APEX EXPO, which took place February 14-16 in San Diego, Calif.
The EA6400 Series, an AA adhesive solution for camera lens assembly, reportedly allows for product-specific glass transition temperature (Tg) from 0-150°C. This capability can provide an extra performance benefit of ensuring a stable product storage modulus in the standard operating range of the devices for reliability improvement. The adhesive is a one-part, premixed adhesive solution with good RT work life. The products are formulated to offer high UV penetration at short UV exposure times (2-5 sec). The formulation reportedly targets specific camera module substrates and shapes stability requirements, while the high Tg capability enables a strong and reliable bond.
