摘要:
An electronic component mounted structure is constituted by connecting together via a conductive adhesive 2 the electrode terminals 1a of a first electronic component such as a semiconductor element 1 and the electrode terminals 6a (here, projecting electrodes formed thereon) of a second electronic component such as a circuit substrate 6, and filling a molding resin 4 into a gap between the semiconductor element 1 and the circuit substrate 6. The molding resin 4 is composed of a low elasticity layer 3 and a high elasticity layer having higher elasticity than the low elasticity layer, and the low elasticity layer 3 lies adjacent to the whole of the outer surface of the conductive adhesive 2.

摘要:
A solder transfer substrate, including: a base layer; an adhesive layer arranged on the base layer; and plural solder powders arranged on the adhesive layer, wherein in the base layer, which is a porous member, a plurality of holes, which allow at least a peeling-off liquid to pass therethrough, are formed from a side thereof on which the adhesive layer is not arranged to a side thereof on which the adhesive layer is arranged. Particularly, the adhesive layer has a characteristic of expanding with the peeling-off liquid infused.
摘要:
A conductive bump formed on an electrode surface of an electronic component. This conductive bump is composed of a plurality of photosensitive resin layers having different conductive filler contents. Consequently, this conductive bump is able to realize conflicting functions, namely, improvement in adhesion strength with the electrode and reduction of contact resistance.
