Innovative adhesive solutions optimise first lens bonding in camera modules

DELO now offers two customised solutions for stabilising camera modules that feature larger sensors and lenses. The DELO DUALBOND SJ and DELO PHOTOBOND FB product families offer first lens bonding, fulfilling the demand for larger sensors and optics in camera module production.

To ensure optimal performance of the camera system, first lens bonding is utilised to accurately join lens packages, improving optical power and compensating for thermal stress between modules of varying sizes. DELO DUALBOND SJ4758 and DELO PHOTOBOND FB4176 are two products recognised for their exceptional adhesion in narrow bonding gaps and effective stress-relief characteristics.

DELO DUALBOND SJ4758 offers rapid light fixation followed by a thermal curing process, making it perfect for opaque or shadowed areas. DELO PHOTOBOND FB4176 ensures fast light fixation in just one to five seconds, providing a drier finish compared to conventional acrylate adhesives. Both products are ideal for passive or active alignment technologies, delivering an adhesion strength of up to 30MPa, even when cured at temperatures of 60C or higher. These adhesives exhibit consistent shrinkage and adhere well to PC and LCP, commonly used in camera modules.

“Our adhesive solutions provide high optical stability by combining fast processing with tension-equalising adhesion. This supports efficient and sustainable manufacturing of advanced camera systems, fulfilling increasing demands for larger and more powerful sensors and optics,” explains Marc Kosiahn, product manager for Consumer Camera at DELO. “We deliver the flexibility and efficiency critical in today’s high-tech production environment.”

These adhesive solutions and others for cameras and optics can be seen at the China International Optoelectronic Exposition (CIOE) 2025, hall 1, booth 1A83, from 10-12 September, in Shenzhen.
