摘要： A solder paste for use in a reducing atmosphere is disclosed. The solder paste includes a solder powder and an alcohol binder. The reducing atmosphere serves as a flux, thereby eliminating flux residues and the problems associated therewith. Solder splattering is reduced by using a polyhydric alcoholic binder which vaporizes or decomposes before the solder liquifies during heating. The use of such a solder paste in a reducing atmosphere results in no hazardous chemical by-products and, because the solder is handled in the form of a paste, is compatible with electrical components requiring precise dimensional tolerances.
摘要翻译：公开了一种用于还原气氛的焊膏。焊膏包括焊料粉末和醇粘合剂。还原气氛用作助熔剂，从而消除助熔剂残余物和与之相关的问题。通过使用在加热期间焊料液化之前蒸发或分解的多元醇粘合剂来降低焊料飞溅。在还原气氛中使用这种焊膏导致没有有害的化学副产物，并且由于焊料以糊状的形式被处理，所以与需要精确的尺寸公差的电气部件兼容。

摘要： An improved method and apparatus for making solder connections from input/output connecting pins to the circuitry on a pinned metallized ceramic substrate. A solder preform in the shape of a sphere provides the correct volume of solder. These spheres are held in position at each desired joint by a templet. The substrate, solder sphere and templet assembly is passed through a furnace in a reducing atmosphere and at a temperature to facilitate solder reflow and wetting, thus creating a sound mechanical and electrical connection between the pin and its portion of the circuitry. The method and apparatus of the invention provides joints have a high degree of reliability such that all connections are made to acceptable soldering standards, none lacking integrity. Only harmless by-products are produced in the practice of the invention, and no residue is produced which requires cleaning by means of chemical solvents and therefore is environmentally superior.

摘要： An electronic package which includes a rigid first substrate (e.g., ceramic) having a plurality of conductive pins spacedly located therein. These pins each include one end portion extending below an undersurface of the substrate for positioning and electrically coupling within a second substrate (e.g., printed circuit board), while also including an opposite end portion which projects from an opposite, upper surface of the first substrate. These upwardly projecting end portions are designed for accommodating, in stacked orientation, a plurality of thin film, flexible circuitized substrates thereon, each of these substrates being electrically coupled to a respective pin, if desired, using a solder composition. In one example of the invention, solder hierarchy for various solders is used, one solder being used to connect the substrates and respective pins, and a second solder (having a higher melting point and different composition from the first solder) used to connect the semiconductor devices (chips) of the flexible circuitized substrates to the conductive circuitry of the substrates. Hydrogen is preferably used to effect solder reflow for the solder which couples the flexible substrates to the respective pins. In an alternate embodiment, the flexible circuitized substrates may include at least two separate conductive layers as part thereof.
