U.S. Patent5,364,277.Nov.15, 1994 WT.Crumly et al., assignors to Hughes Aircraft Co.,

An electrical circuit comprising a dielectric substrate, and a pattern of conductive traces on one side of the substrate with at least one of the conductive traces having a three-dimensional conductive circuit feature formed integrally therewith and projecting from the trace surface in a first direction for providing a readily connectable and disconnectable pressure interconnection to another element.

Electroless Gold Bath

U.S. Patent5,364,478.Nov.15, 1994

A method for producing a brown coated article, wherein an iron substrate is dipped at a temperature of from 430-6OOT in a molten zinc plating bath containing from 0.05-l% by weight of manganese, so as to zinc hot-dip galvanize the same, a heat treatment is carried out to convert a zinc-manganese phase formed by the zinchot dip galvanizing to a zinc-manganeseiron phase, and, subsequently the zinc hot-dip galvanizing layer is brought into contact with an acidic aqueous solution containing an oxidizing agent.

solution that is in the bath; allowing acid solution to overflow at a level from the top of the bath, recirculating at least a portion of the acid etch solution, which overflows from the bath, back into the bath; and maintaining the temperature of the acid etch solution.

An apparatus for coating a substrate, comprising a tubular cathode on which a tubular target is fixed, said cathode being rotatable about a central axis.

U.S. Patent5,364,460. Nov. f5, 1994

K. Morimofo et al, assignors to C. Uyemura & Co. Ltd., Osaka, Japan

An electroless gold plating bath comprising a gold sulfite; a sulfite as a complexing agent for gold ion; at least one reducing agent selected from the group consisting of a hydrazine, ascorbic acid, a salt of ascorbic acid, trimethylamineborane, and dimethylamineborane; and an organic phosphonic acid or a salt thereof.
