Abstract: Encapsulated electrical component assemblies and methods of electrically connecting an electrical component having a plurality of component electrical terminations to a component carrying substrate having a plurality of substrate electrical terminations at surface mount reflow soldering conditions is described. The electrical and substrate components have an encapsulant-forming composition sandwiched therebetween and encasing said pluralities of component and substrate electrical connections. The described invention relates to using an encapsulant-forming composition comprising a thermosetting resin (preferably an epoxy resin) and a cross-linking agent (preferably an anhdride) for said resin that cross-links said resin and that also acts as a fluxing agent and optionally includes a catalyst for initiating cross-linking at required conditions. The gel point of the encapsulant-forming composition is reached after solder melt.

Abstract: Method for controlling the deposition of solder on a base metal or substrate is disclosed. The method comprises applying an attaching flux and finishing flux to a substrate, placing a preform thereon and subjecting the same to reflow conditions. The finishing flux is applied to solubilize the normally insoluble corrosive residues that would occur when the attaching flux is subjected to reflow conditions with the preform and substrate. Alternatively, the attaching flux may be applied to the preform and substrate before undergoing reverse reflow conditions and then the finishing flux is applied to the solder deposit and substrate and the same subjected to second reflow conditions. After each method, the residues left from the attaching flux which are solubilized by the finishing flux, are cleaned by washing with a typical solvent.

Abstract: A presentation apparatus for artwork comprising a one-piece, die-cut folder construction of cardboard or other suitable material. The apparatus comprises a back section containing artwork and one or more side panels which suitable fold over the back section. The one or more side panels contain die-cut windows covered with acetate sheets or cels for viewing the artwork on the back section and may also contain artwork or images providing a three-dimensional effect for the images or artwork.

Abstract: A method of forming a solution of oxalic acid potassium salt dihydrate, useful for desensitizing dentin, comprising the steps of admixing an effective amount of oxalic acid potassium salt dihydrate in water having a pH of 2.0-4.0, heating the solution at a temperature range from 85° F. to 100° F. until a suspension is formed, ultrasonically vibrating this suspension for an effective amount of time and frequency to reduce the oxalic acid potassium salt dihydrate to a particle size of 1 to 10 microns.
