ABSTRACT:
A package contains conductive inks or slurries adapted for attachment to a screen printer for applying the inks to a substrate for firing into printed circuit boards. The bag interior containing the ink is formed between a liquid and gaseous impermeable top wall connected along its periphery to a bottom wall formed with openings through which the ink is adapted to migrate towards the print screen under vacuum. A seal member extends around the entire periphery of the bag and is adapted to sealingly mate with a corresponding fastening element attached to the print frame to form an air seal between the bag and print frame in operative position. A removable, peel-away cover normally covers the screen bottom wall to allow the bag to have a long shelf life.
