Patent number: 6605779Abstract: The present invention protects a thin wire connection from oscillation of a resin protecting an electronic circuit module from vibration, impact, and corrosion. An electronic control unit including an electronic circuit module in which a bare chip is mounted on a circuit board and a case for housing the module, is provided, wherein the case is filled with a potting gel to protect the module. The bare chip, including its wire connection to the circuit board, is sealed in advance with a gelatinous resin having thixotropy prior to hardening. The gelatinous substance cures to form a hardened inner layer which has a penetration that is lower than that of the filled potting gel after hardening, and functions to eliminate or substantially reduce the affect of viscoelastic oscillation of the outer layer on the bare chip and the wire connection.Type: GrantFiled: October 5, 2001Date of Patent: August 12, 2003Assignees: Aisin Aw Co., Ltd., Kyocera CorporationInventors: Hiroki Takata, Kenji Suzuki, Naoto Ogasawara, Toshio Nagata

Patent number: 6302706Abstract: In order to precisely detect positions of respective lead portions of an electronic component and to reduce the cost of production of the electronic component, the electronic component has a resinous pad portion and a plurality of terminal units embedded in the pad portion. Each of the terminal units is provided with lead portions that are disposed parallel to one another with their terminal faces exposed, and junction portions for junction between bonding wires and the lead portions are formed on the terminal faces. Corner portions are formed at predetermined sections on the terminal faces. In this case, even if resin of the pad portion has adhered to the peripheries of the terminal faces and fouled the terminal faces, since the lead portions have the corner portions, images of the lead portions can be detected precisely. Accordingly, the operation of connecting the bonding wires to the terminal faces is performed more efficiently, whereby the cost of production of the electronic component can be reduced.Type: GrantFiled: December 29, 1999Date of Patent: October 16, 2001Assignees: Aisin AW Co., Ltd., Yazaki Parts Co., Ltd.Inventors: Kouji Aokie, Naotaka Murakami, Hiroki Takata, Osamu Yamato, Katsuhiko Onoda
