DEVICE AND METHOD FOR TRANSFERRING FLUX

摘要

PROBLEM TO BE SOLVED: To provide a device and method by which flux can be transferred stably. SOLUTION: In a method by which flux is transferred to solder balls 8 by bringing the balls 8 into contact with a flux film formed on a table 11 by means of squeezes 22a and 22b, preliminary squeezing operations are performed for a prescribed period of time by repeating scrape-up operations and film forming operations before flux transferring are started. Consequently, the viscosity of flux can be stabilized and such a good transfer quality can be secured that no variation occurs in transferred amount by forming a stable flux film when transfer is started.
