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.
Introduction
Ultrasonic welding techniques have been used successfully for over 25 years in many
industries using plastics. The process utilizes a thermoplastic resin's ability to form a welded joint
by generating heat at the joint interface by mechanical vibratory energy. Once the resin becomes
molten or plasticized at the joint it flows across the interface to form a homogeneous link of the two
plastic parts [1]. This welding technique solves many manufacturing problems for industries
concerning bonding and fastening of materials and related labor costs. It will provide a fast,
controlled and repeatable method of achieving a permanent strong bond between two parts.
Originally developed to weld plastics, ultrasonic welding has gained inroads into various
welding applications including metal, surface mount assembly, printed circuit board, and even
textile materials. Although this technology has a higher initial cost than resistance welding and
other assembly techniques, its speed and flexibility provide for a good payback in a short period of
time. Additional advantages, such as its capability to be linked with microprocessors and to be
integrated into automated processes, make it even more attractive to manufacturers seeking a
competitive edge and a "world class" manufacturing capability.
Multi Metal Ultrasonic Bonding
Process Configuration
Multi metal ultrasonic bonding combines ultrasonic metal welding and layered
manufacturing techniques to produce three-dimensional freeform objects. The process uses the
power of high frequency ultrasonic vibration at low amplitudes to bond thin foils of materials to
form solid objects. It combines normal and oscillating shear forces on mating foils; and the resulting
friction forces between materials to fracture and displace surface oxides. The exposed atomically
