Title: Screen printing device and screen printing method
Inventor: ABE SHIGETAKA
IPC: H05K3/12
Filed: 1999-02-04
Abstract: PROBLEM TO BE SOLVED: To upgrade productivity by shortening the tact time while the print quality is maintained at a high level. SOLUTION: This screen printing method is to print a cream solder to a base through pattern holes by bringing a mask plate to the base and supplying the cream solder to the surface of the mask plate to slide a squeegee 13.
