Reducing
Method for Improving the Adhesion of a Deposited Metal Layer US Patent 5,486,266.Jan. 23, 1996
Foam in Spraying
U.S. Patent 5,486,576. Jan. 23, 1996 G.R. Larson et al, assignors to Rohm and Haas Co., Philadelphia
C.S. Tsai and TX. Chang, assignors to Taiwan Semiconductor Mfg. Co., Hsinchu, Taiwan .A method for cleaning the surface of a partially manufactured integrated circuit, just prior to the deposition of a metallic layer onto the surface, comprising dipping in a buffered oxide etch composed of 1 part by volume of hydrofluoric acid, 1 part of ammonium fluoride, and water; immersing the surface in a solution of hydrofluoric acid in water: then immersing the surface in a mixture containing sulfuric acid, hydrogen peroxide, and water; and rinsing in deionized water and drying.
A method for reducing microfoam in a spray-applied waterborne thermoset composition.
Printed Circuit Board U.S. Patent 5,487,218. Jan. 30, 1996 AX. Bhatt et al., assignors to IBM Corp., Armonk, N. Y
A method of preparing a printed circuit board having a film redistribution layer and selective, filled plated-through holes comprising seeding with a palladium-tin suspension to make the exposed surfaces catalytic for electroless copper plating.
Shot Peened Golf Club Head Dual Coated Metal Substrates U.S.Patent 5,486,414. Jan. 23, 1996 0.E. Roberto and M.A. Maxim, assignors Corp., Plymouth Meeting, Pa.
U.S. Patent .5,487,543. Jan. 30, 1996 CR. Funk, Tucson, Ariz.
to Henkel
A method for coating a metal substrate, comprising applying as a first coating an adherent water-insoluble coating comprising a transition metal compound and at least one pulverulent metal in an organic compound matrix: applying onto the first coating an acidic aqueous composition comprising dispersed resin solids and an activator, which converts the water/resin composition into one which will form on a metallic surface a resinous coating that increases in thickness the longer the surface is contacted with the composition to form a second uncured autodeposited coating over the first coating; and curing the uncured autodeposited coating.
Primer Composition U.S.Patent 5,486,567. Jan. 23, 1996 M. Arai et al, assignors Ltd., Tokyo
to Shin-Etsu Chemical Co.
A primer composition comprising a polyorganosiloxane resin containing at least 0.0 I mole of hydroxyl groups per 100 g of the resin; at least one compound selected from the group consisting of an alkoxytitanium and a partially hydrolyzed product thereof; an acid; and a solvent. METAL FINISHING
. NOVEMBER
1996
A treated golf club made by a method, which includes providing a golf club having a metal head with an exposed metal ball striking surface that is shot peened to improve feel with minimal vibration feel in the hands of the user when the user strikes a golf ball and with the shot peening work hardening the exposed metal ball striking surface and creating a compressive stress.
Electroplated Thermoplastic Automotive Grille U.S. Pafenf 5,487,575. Jan. 30, 1996 LA. Chase, assignor to Lacks tndustries Inc., Grand Rapids, Mich.
A method for forming an automobile grille having a decorative coating so as to promote the flexural properties comprising forming the automobile grille to have a first segment, a second segment, and a plurality of support members; and selectively depositing a metal so as to form a decorative metallic layer on the first surface without substantially forming the decorative metallic layer on the second surface; whereby the automobile grille is characterized by enhanced flexural properties in the absence of the decorative metallic layer on the second surface, so as to enable the automobile grille to more readily flex when impacted by an object without plastically deforming
and without cracking the decorative lic layer.
