摘要： A thermal conductive substrate includes a first electrical insulator layer, a second electrical insulator layer and a lead frame serving as a circuit pattern. The first electrical insulator layer is formed of a thermal conductive resin composition containing a thermosetting resin and an inorganic filler, and is joined to the lead frame. The second electrical insulator layer is provided on the side of the first electrical insulator layer not in contact with the lead frame, and is formed of a thermal conductive resin composition containing the inorganic filler and a resin composition containing the thermosetting resin. The second electrical insulator layer has a higher thermal conductivity than the first electrical insulator layer. Thus, it is possible to achieve higher heat-radiating characteristics and component packaging reliability without deteriorating formability and adhesive characteristics of the electrical insulator layers.

摘要： A connecting member of circuit substrates includes an organic porous base material provided with tackfree films on both sides, through-holes disposed at requested places which are filled with conductive resin compound up to the surface of the tackfree films. This structure enables inner-via-hole connection and can therefore attain a connecting member of circuit substrates and an electrical connector of high reliability and high quality. By using a connecting member of circuit substrates including the organic porous base material provided with tackfree films on both sides and through-holes disposed at requested places which are filled with conductive resin compound up to the surface of the tackfree films, it is possible to form a high-multilayer substrate easily from double sided boards or four-layer substrates which can be manufactured rather stably. In addition to that, since the conductive paste is filled up to the surface of the tackfree films, the conductive paste sticks out from the surface of the organic porous base material when the tackfree films are separated. As a result, the filled amount of the conductive substance increases after the lamination, and thus, the connection resistance is reduced considerably.
