摘要： An electrical interconnect pin, particularly suitable for attachment to the edge of a flexible printed circuit board or "flex circuit", has an edge clip with an opening that can be temporarily enlarged to facilitate the attachment of the pin to the edge of a circuit board. The pin includes an elongated shank with a rectangular cross section and two substantially identical clips attached to opposite sides of the shank. To attach the pin to a printed circuit board, the pin is placed on a flat surface with the shank parallel to the surface. A force is then applied to the shank just below the clips and perpendicular to the surface. This force opens up the edge clip and the edge of the printed circuit board is then inserted into the opening of the edge clip. After the force is removed, the edge clip clamps down on the circuit board, temporarily attaching the pin to the board. The pins can then be permanently affixed to the board by soldering.

摘要： A tacking agent is provided for use in temporarily adhering electronic components and providing fluxing properties for soldering electronic assemblies. The tacking agent comprises a fluxing agent and a tackifier. The fluxing agent is composed of one or more carboxylic acids having the formula ##STR1## where R is an alkyl group containing from 1 to 6 carbon atoms, R' is selected from the group consisting of hydrogen and hydroxyl, and R" is selected from the group consisting of hydrogen, hydroxyl and carboxyl. The tackifier comprises one or more alcohols, aromatic hydrocarbon solvents, aliphatic hydrocarbon solvents, or polymers. The tacking agent is deposited onto a printed circuit board or other substrate, the electronic components are placed into the deposited tacking agent and soldered. During solder reflow the fluxing agent provides fluxing action for the soldering process, and the tackifier volatilizes, leaving little or no residue on the printed circuit board.

摘要： A selectively releasing runner and substrate assembly (10) comprises a plurality of conductive runners (16) adhered to a substrate (12). A portion (18) of at least some of the conductive runners have a lower adhesion to the substrate for selectively releasing the conductive runner from the substrate when subjected to thermal stress. The selectively releasing runner and substrate assembly is made by selectively depositing an adhesion layer (14) of a first metal to portions of the surface of the substrate where maximum adhesion is desired. The other portions of the substrate are not covered with the first metal. The first metal layer and the uncovered portions of the substrate surface are covered with a second metal layer (16). The adhesion of the second metal layer to the substrate is less than the adhesion of the second metal layer to the first metal layer, and less than the adhesion of the first metal layer tot he substrate. The second metal layer may be copper. Additionally, an electronic component (22), such as an integrated circuit, may be attached to the selectively releasing metal portion.

摘要： An interconnection mask which is sandwiched between two members to be bonded together is comprised of a thin sheet of preselected material which has a plurality of apertures therein which are positioned, sized, and shaped to define the common bonding areas between the two members whereby structural failures induced by bonding and loading characteristics of the two members are minimized. A method for making an apparatus which utilizes the interconnection mask comprises the steps of preparing a mask of preselected material having a plurality of apertures therein, each aperture being positioned, sized and shaped to define a common bonding area between first and second members of the apparatus whereby the structural failures induced by the bonding and loading characteristics of the two members are minimized; placing a layer of bonding material on a surface of the first member; placing the interconnection mask over the layer of bonding material; placing the second member over the mask; bonding the first and second members together at each common bonding area defined by the apertures in the mask.

摘要： A solder clad printed circuit board (100) consists of an electrically insulating substrate that has copper circuit traces (105), portions of which are solderable. A substantially planar layer (120) of a soldering composition is fused to the solderable traces, to form a solder pad that is not domed. The layer is composed of a mass of off-eutectic solder particles (115) that are fused together to form an agglomeration (120) having a porous structure. The solder particles are fused together by heating the off-eutectic solder to a temperature that is between the solidus temperature and the liquidus temperature of the solder. The solder is then cooled below the solidus temperature to solidify it.
