  • Power doubler amplifier module with improved solder coverage between a heat sink and a thermal pad of a circuit package
    Patent number: 9431317
    Abstract: In one embodiment, an apparatus includes a printed circuit board, and a circuit package mounted to the printed circuit board. The circuit package has a thermal pad. A first heat sink structure of the module is associated with the printed circuit board and has a wall defining a contact surface that contacts and thermally couples with the thermal pad. The wall includes at least one aperture there-through. Solder paste is provided between the contact surface and the thermal pad to bond the contact surface to the thermal pad, with the at least one aperture being constructed and arranged to aid in outgassing of the solder paste.
