PRINTING PLATE, CIRCUIT BOARD AND METHOD OF PRINTING CIRCUIT BOARD

摘要

A printing plate capable of preventing a highly viscous paste sticking to squeegee edge from remaining on a through hole in a circuit board during paste filling by the squeegeeing method. A metal sheet (3) formed with a squeegee cleaning section (7) is fixed to the back surface of the inclined portion (5) of a mask (2) in a printing plate frame (1), and after the highly viscous paste on the squeegee edge has been removed by the squeegee cleaning section (7), the through hole in the circuit board is filled with the paste; thus a circuit board which is capable of preventing the paste from remaining on the through hole and which is superior in quality is obtained.
