Press for printing an electrical circuit component directly onto a substrate using an electrically-conductive liquid
First Claim
1. A press for printing an electrically-conductive liquid directly onto a substrate, comprising:
- a press surface having a printing direction and a direction transverse thereto; and
a plurality of liquid-carrying cells disposed on said press surface for carrying the electrically-conductive liquid, said cells being in liquid communication with each other, below a surface of said press surface, in (i) the printing direction, in (ii) the transverse direction, and in (iii) directions oblique thereto.

Abstract
A press for printing an electrical circuit component directly onto a substrate with an electrically-conductive liquid includes a press surface having a printing direction and a direction transverse thereto. A plurality of liquid-carrying cells are disposed on the press surface for carrying the electrically-conductive liquid, the cells being in liquid communication with each other in both the printing direction and in the transverse direction. A method of making such a press includes the steps of providing a press surface and engraving the press surface with the plurality of liquid-carrying cells which are in liquid communication with each other in both the printing direction and in the transverse direction.

15. A printing press for directly printing a plurality of electrical circuits onto a substrate, comprising:
-
a printing surface for contacting the substrate during the direct printing operation; and an array of liquid-carrying cells disposed on said printing surface, for carrying an electrically-conductive liquid which is deposited on the substrate when said printing surface contacts the substrate during the direct printing operation, said array of cells comprising a plurality of patterns each of which comprises an electrical circuit pattern, each electrical circuit pattern having continuous pathways in a printing direction and in a direction oblique thereto so that when the electrically-conductive liquid is carried by said cells, the liquid in each electrical circuit pattern is conductive in both the printing direction and in the oblique direction. - View Dependent Claims (16, 17, 18, 19)
