Multilevel circuit board precision positioning

A method of establishing the registration of a layer of a discrete wiring board to a surface associated with a wire scribing machine surface which comprises the steps of:

• (a) forming a plurality of first patterns of linear conducting material at a plurality of locations on a panel, said panel being a layer of a discrete wiring board;
• (b) wire scribing a plurality of corresponding second patterns on a surface associated with the wire scribing machine;
• (c) connecting detecting means to said wires second patterns;
• (d) connecting a source of alternating current to said first patterns on said panel;
• (e) translating said panel relative to said surface until said detecting means detects a predetermined condition.

A method of establishing at least one wire scribed conductor on a substrate in registration to the conductive pattern of the substrate, which method comprises the steps of:

• a. wire scribing a plurality of first datum reference conductive patterns on a surface associated with and in fixed relation to the table of a wire scribing machine;
• b. connecting detecting means to said first wire scribed pattern;
• c. providing a substrate having a corresponding plurality of second datum reference conductive patterns on an insulating base;
• d. connecting a source of alternating current to said second corresponding datum reference patterns on the insulating base;
• e. placing the insulating base on the table of the wire scribing machine;
• f. moving the insulating base relative to the table in response to signals from said detecting means until optimum registration between said first and second datam reference conductive patterns is obtained;
• g. wire scribing a conductor layer on the substrate.
