Abstract
Disclosed is a screen printing apparatus for screen printing the cream solder including a squeegee assembly () provided with comb blade members () and with solder leakage prohibiting guides (). The comb blade members partition a cream solder () substantially vertically with respect to a contact slide surface between the squeegee () and the screen () to prevent the cream solder from passing in fluidity on the screen () in a direction substantially at right angles to the sliding direction as the squeegee sweeps and as the cream solder becomes twisted between the screen and the squeegee. The solder leakage prohibiting guides () prevent the cream solder from leaking to outside a printing sphere determined by the squeegee width.
