专利汇可以提供Panel board systems and components therefor专利检索，专利查询，专利分析的服务。并且A panel board system particularly adapted for mounting high speed integrated circuit devices is shown to include integrated circuit packages, connectors and panel board means which each incorporate impedance matching means to provide for complete integrity of the system. The integrated circuit packages have an integrated circuit chip mounted on one side of a ceramic card and have the chip electrically connected to a plurality of printed circuit paths formed on the saem side of the card. These circuit paths terminate in closely spaced relation to each other along one edge of the card and a metal ground plane is formed on the opposite side of the card to provide controlled impedance in the integrated circuit package. Each connector receives an edge of an integrated circuit package and has a plurality of contact means located in closely spaced relation to each other along one side of a dielectric member within the connector for detachably engaging respective circuit path terminations on the integrated circuit package. A metal ground plane formed on the opposite side of this dielectric member provides matching impedance within the connector. Preferably the connector has additional contact means mounted on the ground plane within the connector for detachably engaging the ground plane on the integrated circuit package. Terminal portions of the connector contact means extend from the connector into the panel board, preferably in staggered relation to each other, to be electrically connected to impedance matched circuit path and ground plane means on the panel board, the staggered relationship of the contact terminal portions facilitating electrical connection of the terminal portions to the circuit path and ground plane means of the panel board when connectors are mounted with high density on the panel board. When high speed integrated circuit elements such as emittercoupled logic (ECL) devices and the like are mounted on a conventional panel board system, the performance of the system is limited by the performance of the means employed in the conventional system for electrically connecting the integrated circuits to circuit elements on the panel board. These performance limitations primarily result from the circuit arrangements provided within conventional integrated circuit packages themselves and from the means conventionally employed in making electrical connections between the integrated circuit packages and connectors mounted on the panel board.，下面是Panel board systems and components therefor专利的具体信息内容。
