    Abstract: A method for forming a conductive vias in a non-conductive substrate having a through-hole formed therein intermediate two side thereof. The method utilizes the steps of: applying gold paste to the through-hole so as to provide electrical conduction therethrough; and under firing the gold paste when a thin conductive film is present upon the substrate and fully firing the gold paste when no thin conductive film is present on the substrate. Under firing the gold paste when a thin-film is present upon the substrate prevents degradation of the thin conductive film. Subsequent processing of the gold paste assures the integrity and reliability thereof. Thus, the gold paste provides enhanced conductivity and improved reliability, as compared to contemporary thin-film vias.

    Abstract: A process for fabricating a plurality of solder joints from a low melting point solder paste and high melting point solder balls is described. An abbreviated process flow is as follows: First, the solder balls are placed into cavities in an alignment boat, a vacuum is initiated to hold the boat and solder balls in place. Second, an amount of solder paste is applied directly onto the solder balls in the boat. Third, an alignment plate is placed over the alignment boat to provide a means of roughly aligning the solder ball/solder paste combination to the substrate. Fourth, the substrate is placed through the alignment plate on top of the solder balls in the boat. Pressure is applied to wet the solder paste to the conductive pads on the substrate. Finally, the substrate and alignment boat assembly is processed through a furnace for solder paste reflow. No expensive alignment tools are necessary as the substrate can at least partially realign itself to the array of solder balls during reflow because of the surface tension exerted by the molten solder paste as it wets the entirety of each conductive pad on the substrate.

    Abstract: A process for producing an hermetic feedthrough in a ceramic substrate by providing a sheet of liquid phase sinterable ceramic composition having a feedthrough hole, filling the feedthrough hole with refractory metal metallization material, firing the resulting structure to produce a sintered substrate and adherent metallization wherein the metallization is comprised of continuous phases of refractory metal and glass, contacting the refractory metal with electrically conductive intrusion metal and heating the resulting structure to a temperature at which the glassy phase is fluid, the refractory metal is solid, and the intrusion metal is liquid whereby the liquid metal preferentially wets the refractory metal, migrates into the metallization displacing glass and, upon subsequent solidification, partially or wholly occupies the volume space originally containing the continuous glass phase.
