DELO'S new adhesive enables extremely fast assembly processes in VCM manufacturing.
VCMs are incredibly small motors, with components measuring at mere millimeters and mostly made of temperature-sensitive materials. Assembling them comes with many stringent temperature and quality requirements, making it important finding the right adhesive to establish these bonds. DELO DUALBOND LT2221 is a dual-curing adhesive whose highlight is its low curing temperature at just 60 °C, making it a perfect adhesive solution for many consumer electronics applications.
This low-viscosity adhesive is able to create very fine bondlines, which serves as beneficial for bonding components as small as those in VCMs. With a compression shear strength of up to 8 MPa on LCP, it is as strong of an adhesive as it is versatile.
DELO DUALBOND LT2221 enables extremely fast assembly processes. When using high-intensity DELOLUX curing lamps, it can be light-fixed in just 0.5 seconds, a key benefit given the many bonding tasks in a VCM. Heat-curing of all shadowed areas for achieving final strength can be done all at once, for example in 90 minutes at 60 °C.
”We have a long history of working hands-on with camera module manufacturers to bring them tailor-made solutions, particularly with regard to active alignment,” explains Maximilian Baum, Head of Product Management for consumer electronics assembly and equipment at DELO. “With this universal, yet high-end adhesive, our customers will be able to use it for almost all of the dozens of bonding tasks in a VCM—something that is rare in today’s highly specialized high-tech manufacturing.”
