Abstract:
An electronic appliance, such as a computer and the like, comprising a printed circuit board with printed circuits arranged thereon and electromagnetic components electrically connected thereto, as well as a heat dissipating arrangement for dissipating heat generated by the components to the surrounding atmosphere, a special feature being the fact that the heat dissipating arrangement comprises a heat sink with several separate thermal conductors which are thermically connected to the printed circuits, which thermal conductors can be arranged on the printed circuit board in various positions, each position corresponding to a predetermined heat dissipation direction.
Abstract:
A preferred method for electrically connecting a first and a second component includes inserting a wire pin through a through hole formed in the first component so that a first portion of the wire pin is located within the through hole and a second portion of the wire pin is located within a retaining feature formed at least in part by the second component. The preferred method also includes moving one of the first and the second components in relation to the other of the first and the second components so that the wire pin resiliently deflects thereby establishing a first contact force between the first portion of the wire and the first component, and a second contact force between the second portion of the wire and the second component.

Abstract:
An optical data link 20 comprises a mounting member 22, an optical element assembly 24, a circuit board 26, and a spacer 32. The PGA substrate 22 has a substrate 22a and a plurality of electrically conductive pins 22b. The circuit board 26 has a pair of surfaces. Electronic components 34a to 34e are mounted on the pair of surfaces. The optical element assembly 24 includes a semiconductor optical element 24f. The semiconductor optical element 24f is connected to an electrically conductive layer on the circuit board 26. The spacer 32 functions so as to distance the circuit board 26 from the PGA substrate 22. Since the circuit board 26 is distanced from the PGA substrate 22, the electronic components 34a to 34e can be mounted on both surfaces of the circuit board 22.

Abstract:
A printed circuit board junction box including an outer case and a printed circuit board. The outer case has a top cover and a bottom cover. The printed circuit board has female and male electrical terminals mounted in through-holes that extend from an upper surface to a lower surface of the printed circuit board. One side of the printed circuit board has only male electrical terminals. The printed circuit board is soldered by raising a molten solder container to contact the lower surface of the printed circuit board. The printed circuit board is turned in a heating chamber so that the molten solder flows through the through-holes in the printed circuit board to solder the female and male electrical terminals to the printed circuit board.
