ABSTRACT:
A nozzle apparatus and method of use for extruding a conductive paste through a stencil or screen onto a substrate are disclosed. The nozzle includes a body and a conformable insert for contacting the screen. The method comprises the steps of obtaining a substrate and a patterned screen, contacting the screen with a nozzle comprising a nozzle body and a conformable nozzle insert, and extruding a paste through the nozzle and screen onto the substrate. The apparatus and method are particularly useful for producing patterned lines from extruded pastes in the manufacture of microelectronic components, and are even more particularly adapted for use in producing patterns in substrates having high aspect ratio openings.
