Analysis of ultrasonic tinning
This paper describes experiments on the wettability of tin on oxygen free, high conductivity (OFHC) copper using a ″point source″ ultrasonic horn. Ultrasonics are used on such metals as aluminum or stainless steel which are difficult to wet without the use of very strong corrosives. These experiments explore the behavior of acoustic energy transmission in the horn-solder-substrate systems indicated by the solder film generated and explore the use of ultrasonics in actual electronic systems component fabrication and assembly processes.
