    Abstract: This patent discloses a resolderable connector particularly adapted for interconnecting multilayer modules with circuit boards and the like, but not limited thereto, the multilayer modules including a monolithic ceramic body with interconnected electrical conductors bonded to the ceramic. The modules include conductive terminations on at least one of the external surfaces of the ceramic body. Connected to these external conductive terminations are cuplike receptacles having a good solder wettable interior and a poor solder wettable exterior, the cuplike receptacles being connected to the conductive terminations as by brazing, but at any rate by a means having a higher melting temperature than conventional lead-tin solder so that bringing the receptacles to a temperature to heat the solder so that they may receive pins from projecting circuit boards does not cause release of the receptacles from the ceramic body.

    Abstract: A device for removing contaminant impurities, particularly contaminants existing at very low levels, from a liquid, including a heating element at least partially immersible in the liquid, a confinement means at least partially immersible in the liquid for maintaining a pulsating bubble of vapor of the liquid, the heating element located within the confining means, openings in the confining means to allow periodic partial escape of the vapor bubble and ingress of liquid.

    Abstract: A ball limiting metallurgy pad structure for a semiconductor device solder bond interconnection comprising: a conductive layer that is adherent to the semiconductor device passivating layer, a relatively thick layer of a material having a high thermal conductivity, a barrier layer that protects the high conductivity layer by physically preventing any interaction or alloying with the subsequent layers, and a layer of a material that is solder wettable.
