This project will focus on the collective development of novel ultrasonic bonding
equipment and innovative stretch fibers for the construction of stretch laminates, without the use of hot melt elastic attachment adhesives.
The variables studied included aluminum pad properties, capillary geometry, bond pad design (aluminum pad thickness, aluminum pad coated with nickel layer), and the effect of ultrasonic bonding
The In and Sn-3Ag layers have much lower melting temperatures than the base material (Cu) and can be melted through the heat generated during ultrasonic bonding
, forming intermetallic compounds (IMCs).
For example, with ultrasonic bonding
used on a continuous web, it is easy to stop the line for a problem, but with heat welding, the engaged knives would continue to melt the plastic during a stop.
A high degree of reliability in the heat cycle is ensured through the application of powerful ultrasonic bonding
The IGBT modules integrate a sixth-generation V-IGBT chip to achieve low power loss, and feature a high degree of reliability in the heat cycle by utilizing ultrasonic bonding
The ultrasonic bonding
ability of the Rotosonic machine--the latest creation from Herrmann Ultrasonics--is up to 10 times faster than sewing or gluing processes, according to the Bartlett, IL-based company.
Enables automated deposition and is compatible with thermal compression and ultrasonic bonding
It works well with ultrasonic bonding
, spin welding, adhesive bonding, and heat-staking.
The system ordered encompasses an ultrasonic bonding
head and a high force bonding head equipped with a confinement chamber that reduces oxide on bumps and bonding pads.
To ensure that Sonobond's equipment satisfies specific requirements, it offers a free, no-obligation ultrasonic bonding
viability test to produce sample assemblies with companies' nonwoven or synthetic fabrics.
The IC tag inlay will be produced by applying a propritary ultrasonic bonding
