Patent ID: 8573467

Claim:
A method for dispensing solder on a substrate, the method in sequence comprising: A) heating a substrate to a temperature which lies above a melting temperature of the solder; B) dispensing at least one solder portion on a surface of the substrate; C) after dispensing the at least one solder portion, contacting and lowering a pin into the solder portion until the pin touches the surface of the substrate; D) applying a predetermined force to the pin, so that the pin presses against the substrate; E) applying ultrasonic sound to the pin in such a way that ultrasonic waves are produced in the pin which are directed perpendicularly or angularly in relation to the surface of the substrate; F) moving the pin along a predetermined path which extends parallel to said surface of the substrate, wherein during the moving the pin is located in the solder and ultrasonic sound is applied to the pin; G) terminating the application of ultrasonic sound to the pin after the moving; and then H) lifting the pin until the pin has been severed from the solder portion.
