摘要： A fixture and process for assembly of semiconductor modules. Each module comprises a substrate and a cover attached to the substrate. The fixture comprises a baseplate adapted to accept the substrate and a spring-loading device containing a shape memory alloy spring engaging the cover. The shape memory alloy spring exerts a lesser force at room temperature and an elevated force at the bonding temperature of the bonding agent used to attach the cover to the substrate. The process comprises the steps of (a) loading she module into an assembly fixture and aligning a shape memory alloy spring over the module at room temperature; (b) placing the fixture and module into a heating chamber; (c) heating the fixture and module to a temperature sufficient for bonding and above the shape memory alloy spring transition temperature range so that the spring exerts an elevated force on the module; and (d) cooping the fixture and module below the transition temperature so that the spring exerts a lesser amount of force on the module, and disengaging the springs at the lower temperature.

摘要： A medical device includes a pulse generator, a lead, and an electrode. The lead includes an electrode and a lead conductor connecting the pulse generator with the electrode via first and second conductive paths. The medical device includes first and second switches. The first switch includes a non-conductive state in the presence of a magnetic field, the non-conductive state preventing formation of the first conductive path between the pulse generator and the electrode. The second switch includes a non-conductive state that prevents formation of the second conductive path between the pulse generator and the electrode. The first switch in the non-conductive state and the second switch in the non-conductive state electrically shields the electrode from electromagnetic radiation and induced voltages during a magnetic resonance imaging procedure.
