PROBLEM TO BE SOLVED: To provide a system which rapidly makes appropriate screen printing conditions ensuing from the switching of the model of a circuit board and the change of a solder paste, when the solder paste is screen-printed to the circuit board in an actual production. SOLUTION: In this screen printing method, the actual results of printing to a production substrate are accumulated as templates and the templates are used or the results of test printing are analyzed using a test substrate, a test screen mask and a test paste, and the analytical results are registered as the templates; and the printing conditions are set up based on the template data, when the actual production is started. Refer to Fig.10 and step 8. COPYRIGHT: (C)2005,JPO&NCIPI
