Title:
ELECTRICALLY CONDUCTIVE STRUCTURED SHEETS
Document Type and Number:
WIPO Patent Application WO/1995/018476
Kind Code:
A1
Abstract:
The present invention provides electrically conductive sheet materials (10) that contain columns of electrically conductive particles aligned to form continuous columns (19) between lateral faces of the conductive sheet material (10). The particle columns (19) are arranged so that the sheet is conductive through the thickness, but is electrically insulating in lateral directions. The present invention also provides methods by which such electrically conductive sheet materials (10) can be made. The present invention is able to provide conductive pathways in a precise, regular array, at a very fine pitch.
