SQUEEGEE APPARATUS FOR PRINTING SOLDER PASTE, BUILT-IN SPREAD ROLLER FOR PREVENTING FAULT PRINTING AND METHOD FOR PRINTING SOLDER PASTE THEREBY PREVENTING FAULT PRINTING

摘要

PURPOSE: A squeeze device for solder paste printing comprising a spread roller for preventing printing detects and a solder paste printing method with a printing defects preventing function are provided to accurately print the patterns of a PCB since solder paste is evenly filled in the hole on a metallic mask since a spread roller spreads solder paste before the solder paste is pushed by squeeze. CONSTITUTION: A squeeze device for solder paste printing comprising a spread roller for preventing printing detects comprises squeeze(10), a squeeze head, a spread fork arm(100), and a spread roller(200). The squeeze moves along the top of a metallic mask(M) at an angle. The squeeze prints solder paste on the pattern of a PCB(P), which is located under the metallic mask. The spread fork arm is formed forward in the moving direction of the squeegee. The spread fork arm is coupled by a connecting member(102) to move simultaneously with the moving of the squeeze before the squeeze.
