Application and selection of dual curing UV glue in focusing

In the focusing process of camera modules, what many teams really need to solve is not whether the glue can cure, but whether the glue can stably cure in both illuminated and dark areas, and maintain the focal length without drifting under subsequent thermal shock, humidity, vibration, and assembly stress. Firstly, the conclusion is that for CCM focusing scenes with occlusions, structural shadows, local deep grooves, or lens holder occlusions, a single light curing system often cannot cover all risks. Using dual curing UV glue is usually more conducive to balancing fast positioning in the front section and fixing dark areas in the back section, helping engineering, production, and procurement teams obtain clearer process windows.

If the current project is evaluating the matching relationship between different camera module structures, lens holder materials, and curing station configurations, it is possible to first understand the common dispensing positions, curing methods, and reliability concerns in the optoelectronic assembly scene by combining the adhesive application scheme for optoelectronic modules, and then return to the specific CCM focusing process for more detailed material screening, which will make it easier to narrow down the sample range.
