Abstract:
Process for manufacturing an apparatus comprising at least one substrate and at least one component, said substrate having a surface with a plurality of bonding pads which are metal, said component having a plurality of bonding pads, the bonding pads on the substrate corresponding to the bonding pads on the component, said component being attached to and in electrical contact with said substrate, characterized in that said process comprises the following steps:dispensing an adhesive onto said bonding pads of said substrate or onto said bonding pads of said component; drying said adhesive; applying an underfill material on an area situated between said bonding pads of said substrate; aligning the bonding pads of said component with at least some of the bonding pads of the substrate; exerting a mechanical pressure on said component; and curing said adhesive and said underfill material, said step of curing being performed while maintaining said mechanical pressure, thereby creating electrical contacts between said component and said substrate, wherein during the step of exerting a mechanical pressure on said component, said underfill material substantially fills the non-bonding area of the substrate.
