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.
Claims8
An electrical device including:
- 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, but not set in the conductive layer, to join the dielectric material to the metal layer;
- and
- wherein the metal layer forms a portion of multiple layers of circuitry in an electrical device.
