A Review on Ultrasonic Welding Capability: Breakaway from Traditional Plastic

Abstract

The joint technology using ultrasonic welding is used to bond plastic material. Currently there are many researches to study the feasibility of using ultrasonic bonding to joint other materials. This paper reviewed the study on using ultrasonic bonding to joint multi metal, surface mount component, and textile material. The process configurations of each material are discussed and the results for each study are also presented. The multi metal materials bonding result shows that these materials bonded well to each other. The ultrasonic bonding strength for SMT components was as good as reflow oven and it was cosmetically accepted. The configuration of textile materials is investigated using vibrating ultrasonic horn and stationary anvil using high mechanical vibration and the result show it can be integrated ultrasonically. With advancement of computer control in ultrasonic welding, this technology can be used for any material in future to achieve world class manufacturing.
