6700069, Mar 2, 2004

Filed:

Oct 20, 2000

Appl. No.:

09/694099

Inventors:

Brian J. McDermott - Winter Springs FL
Daniel McGowan - Casselberry FL
Sid Tryzbiak - Winter Springs FL

Assignee:

Peter K. Trzyna - Chicago IL

International Classification:

H05K 103

US Classification:

174255, 174250

Abstract:

A multilayer electrical device, such as a printed circuit board, having a tooth structure including a metal layer set in a dielectric. The device includes a base; a conductive layer adjacent to the base; a dielectric material adjacent to conductive layer; a tooth structure including a metal layer set in the dielectric material to join the dielectric material to the metal layer; and wherein the metal layer forms a portion of circuitry in a circuit board having multiple layers of circuitry.

Inventors:

Brian J. McDermott - Winter Springs FL
Daniel McGowan - Casselberry FL
Ralph Leo Spotts - Lake Mary FL
Sid Tryzbiak - Winter Springs FL

International Classification:

H01K 310

US Classification:

29852

Abstract:

A multilayer electrical device such as a printed circuit board, and method for making the electrical device, having a tooth structure for joining at least one of the layers. The method includes the following steps: providing a base; preparing the base and adding a conductive layer to the base; applying a dielectric material to the conductive layer; preparing the applied dielectric material for receipt of the conductive coating; forming openings (vias) through holes in the applied dielectric coating; etching cavities in the applied dielectric material; applying a conductive coating to the cavities in the applied dielectric material; and forming a metal layer on the conductive coating to produce a tooth structure set in the dielectric coating. The tooth structure preferably has obtuse teeth in the range of 1-2 tenths of a mil deep that mechanically join a dielectric material to a subsequently added metal layer.
