Abstract: A vibration-sensitive module having a mounting flange is mounted to a vibrational base with a bushing assembly secured to the base, where the mounting flange has cammed surfaces radially adjacent to the bushing assembly that variably engage the radial peripheries of the bushings in response to vibrational movement of the base. The cammed surfaces produce a desired force vs. deflection characteristic of the mounting apparatus, and the bushing material retains its compressibility under load to minimize cross-coupling of vibrational force impulses.

Abstract: A process for electrophoretically coating an electrically conductive substrate involves providing an electrically conductive substrate that is to be electrophoretically coated, pretreating the substrate surface to increase its asperity, and applying an electrophoretic coating composition to the treated substrate surface. The process allows the use of conventional electrophoretic coating compositions and/or processing equipment to achieve thicker coatings and/or to develop electrically conductive electrophoretically coated surfaces employing conventional electrophoretic coating compositions, processing parameters and/or equipment.

Abstract: A process for stabilizing an electrical component having a body and electrical leads projecting from the body and received in through-holes defined in a substrate, while avoiding disadvantages associated with dispensing a hot-melt adhesive during assembly of an electrical package, involves steps of providing a circuit substrate having through-holes for receiving the leads of a leaded electrical component, providing an electrical component having a body and leads extending from the body, positioning a preformed hot-melt adhesive on the circuit substrate or on the electrical component, positioning the electrical component on the circuit substrate so that the leads extend into the through-holes and so that the preformed hot-melt adhesive is positioned between and fills the gap between the body of the electrical component and the substrate, and activating and solidifying the hot-melt adhesive to securely adhere the body of the electrical component to the substrate.

Abstract: An electronic component arrangement includes a discrete electronic component having first and second terminals and a centre-exposed pad. A substrate has a first electrical conductor electrically connected to the first terminal, a second electrical conductor electrically connected to the second terminal, and a third electrical conductor. A thermally conductive element is in direct thermal communication with both the centre-exposed pad of the electronic component and the third electrical conductor of the substrate.

Abstract: An electronic package (10) is provided which includes a circuit board (12) having a substrate (14) and circuitry (16) and a surface mount device (22) having a contact terminal (24). A mounting pad (28) is formed on the circuit board (12). The electronic package (10) also includes a solder joint (30) connecting the contact terminal (24) of the surface mount device (22) to the mounting pad (28) on the circuit board (12). The solder joint (30) includes a reflowable solder and a plurality of stand-off members (32 or 42). The stand-off members (32 or 42) provide a separation distance (H) between the circuit board (12) and surface mount device (22) in the range of about 0.01 mm to 0.10 mm.

Abstract: A worktool transfer apparatus for moving a worktool along a recirculating path includes a chain moveably supported by two spaced sprockets of equal diameter. A motor rotates one of the sprockets to cause circulating movement of the chain. A constant breadth velocity cam is fixedly attached to one of the chain links so that the rotational center of the velocity cam is aligned with the rotational centers of each of the sprockets as the link to which the velocity cam is attached moves about the periphery of each sprocket. Four rollers extend from the cam and ride along an oval track for maintaining orientation of the velocity cam as it moves with the chain. A cross bearing block is moved linearly back and forth by the velocity cam. A worktool is attached to and moves with the cross bearing block and is independently moveable laterally of the cross bearing block.
