Method For Enhancing The Solderability Of A Surface

US Patent:
6444109, Sep 3, 2002
Filed:
Oct 26, 2000
Appl. No.:
09/698370
Inventors:
Ronald Redline - Prospect CT, 06712
David Sawoska - Watertown CT
Peter Kukanskis - Woodbury CT
International Classification:
C25D 554
US Classification:
205 85, 106 123, 427 98, 427125
Abstract:
A method for enhancing the solderability of a metallic surface is disclosed where the metallic surface is plated with an immersion silver plate prior to soldering, which immersion silver plate is treated with an additive selected from the group consisting of fatty amines, fatty amides, quaternary salts, ampihateric salts, resinous amines, resinous amides, fatty acids, resinous acids, ethoxylated derivatives of any of the foregoing, and mixtures of any of the foregoing. The immersion silver deposits created are resistant to electromigration.

Method For The Manufacture Of Printed Circuit Boards With Plated Resistors

US Patent:
6585904, Jul 1, 2003
Filed:
Feb 15, 2001
Appl. No.:
09/784242
Inventors:
Peter Kukanskis - Woodbury CT, 06798
Dennis Fritz - Brookville IN, 47012
Frank Durso - Cheshire CT, 06410
Steven Castaldi - Torrington CT, 06790
David Sawoska - Watertown CT, 06795
International Classification:
H01B 1300
US Classification:
216 13, 216 67, 216 65, 216 74, 216 75, 21912169, 438382, 257690, 174250
Abstract:
A process is revealed whereby resistors can be manufactured integral with a printed circuit board by plating the resistors onto the insulative substrate. Uniformization of the insulative substrate through etching and oxidation of the plated resistor are discussed as techniques for improving the uniformity and consistency of the plated resistors. Trimming and baking are also disclosed as methods for adjusting and stabilizing the resistance of the plated resistors.

Method For The Manufacture Of Printed Circuit Boards With Integral Plated Resistors

US Patent:
6767445, Jul 27, 2004
Filed:
Oct 16, 2002
Appl. No.:
10/271817
Inventors:
Peter Kukanskis - Woodbury CT, 06798
Frank Durso - Cheshire CT, 06410
David Sawoska - Watertown CT, 06795
International Classification:
H05K 100
US Classification:
205125, 205126, 205196, 205205, 205208, 205220, 427 98, 427259, 427282, 427304, 427305, 427404, 4274431, 438382
Abstract:
The present invention is a process for manufacturing resistors integral with the printed circuit board by plating the resistors onto the insulative substrate. The invention uses a mask during the activation step so as to selectively activate only selected portions of the surface thus enabling smaller areas to be plated on the printed circuit board because no plating mask is used. The process of the instant invention produced printed circuit boards having greater uniformity and reliability as compared to the prior art.
