  • Publication number: 20230175541
    Abstract: An interface component is disposed between a movable block and a support member, such as a linear rail. The interface includes a number of independent flexures, each providing an axially projected contact area extending toward the support member that varies in shape and spring force according to contact force with the support member. The flexures may be arranged collectively to provide complementary radial forces on the support member, thus providing force-controlled contact points with the support member that can individually yield to local surface irregularities in the support member, while maintaining a balanced array of radial contact forces with the support member.

  • Patent number: 9296056
    Abstract: An apparatus includes a top plate sized to cover components for a PCB in a solder operation to attach the components to a top surface of the PCB. The apparatus may include heat shielding devices and/or heat attracting devices. Each heat shielding device reduces heat transfer to a component to be soldered to the PCB and is positioned in the top plate to decrease heat to the component corresponding to the heat shielding device. Each heat attracting device increases heat transfer to a component to be soldered to the PCB and each heat attracting device is positioned in the top plate to increase heat to the component under the heat attracting device. The top plate is coupled to the heat shielding and/or heat attracting devices and includes a recess for each component configured with a heat shielding device or a heat attracting device.

  • Patent number: 7690108
    Abstract: A unique self-compensating structure mounted to a printed circuit board (PCB) includes a compensating block element having a back portion with at least a first guide surface and a front portion with at least a third guide surface. A mechanical support member having at least a second guide surface with at least a guide element disposed thereon for sliding engagement with the at least a first guide surface. At least a complaint member cooperatively positioned between a surface on the compensating block element and the at least a third guide surface on the mechanical support member. The at least a third guide surface being cooperatively and movably associated along a back portion of an electrical socket connector via the at least a complaint member for compensating and absorbing external stress and strain of a plug-in connector during alternating plugging and unplugging of the plug-in connector from the socket connector, while simultaneously mitigating damage to the PCB.

  • Patent number: 6892781
    Abstract: A fixture having a bottom plate, top plate and an expansion block interposed between the bottom plate and top plate. A workpiece is positioned between the expansion block and bottom plate. When the fixture is heated, there is a net displacement exerted by the expansion block so as to apply pressure to the workpiece. The pressure applied by the fixture to the workpiece is due solely to the thermal expansion of the fixture when it is heated.

  • Patent number: 6131794
    Abstract: A shaving or shearing blade utilized in dressing solder joint chip technologies without the use of heat or a copper block wicking process. In essence, any solder debris resulting from the solder shaving process as implemented by the shaving blade is removed through the intermediary of a vacuum arrangement located as an integral structure in the shaving blade so as to inhibit the potential formation of electrical shorts or causing solder damage in subsequent replacement chip joins or other assembly operations.
