  • Patent number: 4345300
    Abstract: A circuit module (10) having a row of connector pins (21) and being approximately 4mm. thick or less, and including an electrical circuit (22) connected to the connector pins (21). In prior art designs, it has not been possible to utilize a large substrate having good heat dissipation properties and, at the same time, include an attached electrical device, without exceeding the allowed maximum dimensions of the module. The present invention solves the problem by recessing an edge (17) of the substrate (11), depositing spaced-apart conductor films (26a and 26b) in the recess (16) that electrically connect with the eletrical circuit (22), and soldering (31a and 31b) the electrical device (30) to the conductor films (26a and 26b). Principal uses for the invention include digital computers and similar complex electronic devices.

  • Patent number: 4339784
    Abstract: Soldering techniques, where a circuit component having a row of closely spaced leads (e.g., dual in-line packages) are to be soldered to a printed circuit board and the leads are oriented on the printed circuit board such that the row of leads is arranged parallel to the direction of motion of the printed circuit board through a wave solder pot, may effect a high incidence of soldering bridging. This bridging may form between the last few adjacent leads in the row which emerges from the solder pot. A printed circuit board is provided with an additional foil pad (or a pair of additional pads in the case of a dual in-line package) arranged in line with the row of leads. This additional foil pad tends to draw off any excess solder to reduce the solder bridging between adjacent leads during the soldering operation.

  • Patent number: 4335272
    Abstract: Disclosed is a perforated circuit board with a linear arrangement of paired terminals through which jumper wires are inserted and which are positioned on each side of and adjacent to the perforations. The perforations permit flexible "breaking" of the circuit board into sections which may be oriented at any angle relative to one another while the machine-inserted jumper wires provide structural integrity and rigidity for the circuit board arrangement thus formed in addition to electrical coupling between adjacent board sections.

  • Patent number: 4332001
    Abstract: In order to assist the mounting of a printed circuit board to a metallic frame and the soldering of a conductive pattern of the former to the latter, a wire rod of high solderability is bent to conform substantially with the outline of the frame and is disposed at the juncture between the frame and the marginal edge of the circuit board. The circuit board can thus be temporarily fixed to the frame by the resilience of the wire rod and then subjected to dip soldering.
