Connecting structure of terminal area of printed circuit board
First Claim
1. A printed circuit board assembly comprising a printed circuit board having a first terminal area which is electrically connected to a sheet member having a second terminal area;
- said first terminal area of said printed circuit board comprising a substrate having a plurality of spaced-apart first terminals formed thereon;
said second terminal area comprising a plurality of spaced-apart second terminals corresponding to said first terminals formed on said sheet member, said second terminals each including a first layer of an electrically conductive material and a second layer of an electrically conductive hot-melt adhesive, and the spaces around said second terminals having a layer of electrically insulating hot-melt adhesive formed to a thickness greater than the thickness of said second terminals such that the surface of said insulating layer protrudes above the surface of said second terminals; and
said first and second terminal areas being electrically connected and bonded together by said hot-melt adhesives, wherein said electrically conductive adhesive layer of said second terminals are bonded in registration with said first terminals, and said electrically insulating adhesive layer in the spaces around said second terminals being bonded to said substrate of said printed circuit board in the spaces around said first terminals.

Abstract
A printed circuit board has a terminal area to which the terminal area of a sheet member is electrically connected. The sheet member is bonded to the printed circuit board with a hot-melt adhesive. The layer of the hot-melt adhesive which is formed on the sheet member and does not face the terminal area of the printed circuit board protrudes from the surface of the terminal area of the sheet member. The printed circuit board includes an insulating substrate made from a material containing silicon dioxide. A metal salt that imparts hydrophobicity to the bonded surface of the substrate is added to the layer of the hot-melt adhesive.
