Abstract
A screen printer for printing paste on a board by sliding a squeegee head on a mask plate. A pushing plate pressurizes solder paste in the squeegee head, and pressurized paste is led to a paste container from both outer parts in a printing width direction inward towards a printing center through a solder dispensing hole provided on both ends of the paste container. This configuration allows to print in accordance with the time-line supply sequence, regardless of the printing width of the board to be printed. This screen printer thus prevents the degradation and the consequent need for disposal of solder paste due to its retention in the squeegee head for long periods.
