Abstract:
A method comprising:depositing a desired quantity of an uncured, ultraviolet radiation-curable, anisotropic conductive adhesive in a desired location on a metallized glass substrate having an electric circuit formed on a surface of said substrate; applying to said uncured, deposited adhesive an electronic component, said electronic component having electrical contact bumps formed on a portion thereof, said electronic component being oriented so that said bumps are positiioned in said adhesive and in register with desired portions of said electric circuit on said substrate; applying to said electronic component an amount of pressure sufficient to render said adhesive selectively conductive at locations between said electric circuit and said electrical contact bumps on said active device and substantially nonconductive at other locations, such that said bumps make electrical contact with desired portions of said electric circuit, wherein said pressure is applied to said active device by a die positioned on top of said active device and wherein additional pressure is applied to said active device by positioning a diaphragm on top of said die and applying a vacuum to said diaphragm; and irradiating said adhesive with sufficient ultraviolet radiation to substantially cure said adhesive.
