    摘要: This invention provides an aluminum enamel board having an electrically insulating glass layer formed on an Al-Si alloy plate containing at least 5 wt % of Si or a composite metal plate having an aluminum or alloy layer formed on at least one side of a metal plate made of a metal other than aluminum. Since the Al-Si alloy plate containing at least 5 wt % of Si or a composite metal plate having the aluminum or aluminum alloy layer is used as a board, the adhesion strength between the metal plate and the electrically insulating glass layer can be increased. At the same time, a predetermined material is used to form the electrically insulating glass layer, thereby minimizing a difference in thermal conductivity and thermal expansion coefficient between the electrically insulating glass layer and the metal plate. This improves the heat conduction characteristics of the board and prevents warping of the board.

    摘要: This invention presents a new anisotropic conductive film for conductive connections, its method of manufacture, and connectors which use the same, which reduces the connection resistance of semiconductor and similar devices, to the circuit substrates, and simultaneously simplifies the repair. Copper foil 2 is bonded on both sides to an electrical insulating film 3. Holes are formed in the copper foil 2 by etching, and through-holes 5 are formed in the aforesaid electrical insulating film 3, using copper foil 2 as a mask for etching. Next, the through-holes 5 are filled with a conductive elastomer 6, and hardened. The copper foil 2 is then etched to form protuberances 4 of elastomer 6 having the same viscosity. The conducting elastomer 6 protuberance 4 on one side makes contact with the semiconductor device pad, while the protuberance 4 on the other side makes contact with the substrate-side pad. A conductive connection is made by pressing both together.

    摘要: Disclosed is an improved integrated circuit socket having electrically conductive pads formed on a resilient circuitry component for contacting the terminals of an integrated circuit (IC) package which is positioned on the resilient circuitry. The electrically conductive pads are arranged around the center area of the resilient circuitry to be in one-to-one correspondence with the terminals of the IC package. The electrically conductive pads have individual circuit paths of substantially the same length and which are extending outwardly from the center area of the flexible circuitry, and additional electrically conductive pads are formed on the back side of the flexible circuitry in order to effect the required electrical connections to exterior circuits. These electrically conductive pads on the back side are connected to the conductor pattern on the front side by conductive through holes or vias. With this arrangement all conductors have the same, reduced inductance. An insulative apertured film is preferably positioned intermediate the IC package and the flexible circuitry having the electrically conductive pads in order to perform certain alignment and pressure application functions.
