  • Ground connector assembly with substrate strain relief and method of making same
    Patent number: 6740824
    Abstract: A ground connector assembly (20) having a substrate (22) and a ground member (24). The substrate (22) is used to retain an electrical circuit and has a ground region (34), a ground hole (30), and at least one strain relief slot (32). The ground member (24) is attached within the ground hole (30). The ground region (34) surrounds the ground hole (30) and is at least partially interposed between the ground hole (30) and the strain relief slot (32). The ground connector assembly (20) may further include a conductive ring (42), such as a copper ring, surrounding the ground hole (30) and attached to the ground region (34). There is also a method of making the ground connector assembly (20).
    Type: Grant

  • Electrical device having atmospheric isolation
    Patent number: 6053049
    Abstract: An electrical device (10) includes a package body (12) having a device mounting region (14) and an electrical connection region (16). A cavity (18) resides in the package body (12) intermediate to the device mounting region (14) and to the electrical connection region (16). A leadframe (20) is positioned within the package body (12) and includes a plurality of individual leads (34) traversing the cavity (18). An electronic component (24) is electrically attached to the individual leads (34) within the cavity (18). In addition to accommodating the attachment of the electronic component (24), the cavity (18) is configured to permit access to the individual leads (34) by a bonding tool (40).

  • Method for filling a cavity, such as a sensor cavity, with an incompressible fluid
    Patent number: 4928376
    Abstract: A method for oil filling an internal pressure sensor cavity (20) is disclosed which minimizes manufacturing process time and insures totally and properly filling the internal cavity with oil. A predetermined amount of oil (23) is added to a pressure sensor external cavity (21) connected through an opening (22) to an internal sensor cavity (20) having a sensing element (17) therein. A vacuum is drawn while the oil is in the external cavity thus providing at least a partial vacuum in at least the internal cavity. Then vacuum pressure is released causing the oil to be drawn into the internal cavity through the opening. Subsequently a sealing means (27) is force fit in the opening to seal the internal cavity.
