    Abstract: A heat sink assembly includes a printed wiring board (20), a metal case (18) and a circuit package (10) containing a gallium arsenide field effect transistor heat dissipating circuit. The circuit package includes a metal slug (14) formed integrally with the circuit package, the heat dissipating circuit being bonded to an obverse surface of the metal slug. The printed wiring board includes first and second metal lands (22), the first metal land being disposed on an obverse surface of the printed wiring board, the second metal land being disposed on a reverse surface of the printed wiring board. A solder film is formed bonded to and thermally coupling a reverse surface of the metal slug to the first metal land, and a plurality of solder posts are formed, each post bonding to and thermally coupling the first metal land to the second metal land. The metal case is squeezed therebetween. At least one bolt (56) extends through a hole in the printed wiring board and into the metal case so as to squeeze together the metal case, the printed wiring board, the first and second metal lands and the grease film.

    Abstract: PROBLEM TO BE SOLVED: To secure desired soldering strength in an electronic component to be packaged, and to improve heat radiation properties. SOLUTION: On the surface layer of a printed circuit board 14 composed of a copper foil pattern 22 formed of first to sixth layers 14a-14f, there is an inner via 30 extended along a lamination direction and formed while the inner via does not pass through the inner layer of the printed circuit board 14. In the inner layer of the printed circuit board 14, there is a core via 32 extended along a lamination direction and formed while the core via does not pass through the surface layer of the printed circuit board 14. The inner and core vias 30, 32 are offset at a prescribed space along the copper foil pattern 22 formed on the lamination surface for arrangement. COPYRIGHT: (C)2009,JPO&INPIT
