Abstract
A method of laminating a structure comprises at least two layers and a photopolymerizable adhesive composition between the layers, at least one of the layers being opaque, colored, or reflective. One or both of the layers is transmissive to actinic radiation in wavelengths in the range of greater than 400 nm and up to 1200 nm. The photopolymerizable adhesive composition absorbs radiation in the identified spectral region of the radiation transmissive layer. Curing is effected by directing radiation in the identified spectral region through the radiation transmissive layer and produces a laminated structure. An underfilled flip chip assembly on an integrated circuit board substrate can be prepared by the method described above. The photopolymerizable adhesive composition can be applied directly to one or both surfaces of an aligned integrated chip and circuit board substrate or the chip aligned on an integrated circuit board substrate can be capillary underfilled with the photopolymerizable adhesive composition, which is subsequently cured. Data storage disks can also be prepared by the method of the invention.
