The hybrid curing adhesive for image sensor module

The production of the CMOS and CCD sensor packages for the cellular phone has been increasing rapidly. The CMOS and CCD sensor packages are composed with the holder, glass, lens, substrate, sensor and so on. The adhesive to seal up a holder and substrate is necessary. Heat curing adhesive is usually used, and it must have curability at low temperature and enough adhesion. The projection that was arranged by a retainer of a holder and the hole which was emptied into a substrate are used to fix the place, since the position or an axis gap occurs by vibration during transportation and curing. The position or axis gap is the serious problem for an image sensor module.
