ABSTRACT:
A method for soldering a first component having a metal surface to a second component having a metal surface includes holding the metal surface of the first component in a position above a placement area on the metal surface of the second component to establish a gap between the surfaces. The method further includes reflowing solder within the gap.
A structure including a thermally conductive baseplate, an electrical insulator attached to the baseplate, and a metallic shield mounted on the insulator. The structure also includes an integrated power device having a power-dissipating electronic device, and a first metal layer connected to the shield through a solder joint. A substrate includes an aperture, and the integrated power device is mounted with the power-dissipating device sitting within the aperture. The substrate also includes a conductive run electrically connected to a second metal layer of the integrated power device.
A method for use in making a package for electrical circuits includes attaching an electrical insulator within a recess of a first metallic component. The method also includes registering a second metallic component within the recess using a template tool and bonding the second metallic component to the insulator. A third component is soldered to the second metallic component.
A structure including an electrical conductor and a sheet of conductive material including a punt soldered to the electrical conductor
