Die for depositing at least one conductive fluid onto a substrate, and device including such a matrix and deposition method

Abstract

The invention relates to a die for depositing a conductive fluid onto a substrate, including a structure () for supporting at least one fluid () which is conductive and the viscosity of which sensitive to the radiation from a light source (), in order to deposit said fluid () onto a substrate () so as to form conductive contacts or tracks on the substrate (). The support structure () includes at least one tank () for said conductive fluid, the bottom wall () of which is to be arranged opposite said substrate () during the deposition, and said bottom wall () has perforations for enabling the flow () of said conductive fluid () onto the substrate () when said fluid () is subjected to the radiation () from said light source (), wherein the perforations are formed according to a pattern of the fluid to be deposited onto the substrate (). The die () further comprises an optical plate () having a pattern () pervious to the radiation from said light source (), the optical plate () being impervious to the radiation from said light source () outside said pattern (), while the pattern () pervious to the radiation from said light source on said optical plate () corresponds to a pattern covering the pattern () of the perforations of said support structure.
