Research Abstract

1.Frequency characteristics of ultrasonic welding High-frequency systems at 90-780 kHz have been shown that high-frequency systems become to be significantly effective in comparison to a conventional system at 60 kHz. The required vibration velocity v and displacement amplitude xi decrease as frequency increases. v=Af^<-0.6>, xi=Bf^<-1.49> A,B : constants. A peak-to-zero value of 0.04 mum at 780 kHz is 1/30 of that at 60 kHz.
2.Complex vibration locus welding tip was found to be effective for improving the welding characteristics. Welding characteristics and temperature rise of ultrasonic wire bonding using 190 kHz circular and square vibration loci are equivalent to these of a 600 kHz linear vibration locus. Complex vibration welding tips which vibrate in elliptical to circular or rectangular to square shapes at either the same or different frequencies effectively joined welding specimens successfully in shorter welding times, under smaller vibration amplitudes, and over wider good welding areas in comparison to linear locus.
3.High-frequency longitudinal to complex transverse vibration systems 160 kHz - 1 MHz were proposed for ultrasonic ball bonding using a ceramic capillary. Aluminum wire specimens of 0.1 mm diameter were successfully joined using the 400 kHz longitudinal-complex transverse vibration system.
4.The conventional ceramic capillaries were found vibrating with two or three nodes along the capillary at 400 kHz - 1 MHz. The vibration velocity amplitude obtained at the welding tip is sufficient for successful welding.
5.The welding characteristics of the ultrasonic wire bonding were found to be significantly improved by these results obtained by this research. The high-frequency welding systems available in two vibration frequencies, for an example 160 and 500 kHz, were developed.
6.The automatic system using high-frequency and complex vibration systems is under working, and also welding characteristics using ultra-high frequency is under investigation.
