First Time Quality (Page 4)

Ultrasonic wire bonding (UWB), today’s preferred method for joining wires to battery packs in electric vehicles, requires very high surface cleanliness to assure successful bonds. Decontaminating battery terminals, however, can be a very difficult and time-consuming task. EWI has recently completed a study using laser cleaning technology on batteries prior to UWB of aluminum wire...

The integrity of joints (“stack-ups”) in vehicle frames is of utmost importance when it comes to safety, dependability, and public confidence in the automotive industry. But with up to a hundred joint variations in a car’s body-in-white, it is difficult to predict joint strength properties without extensive testing. Until now. EWI has developed a rapid...

In metal additive manufacturing (AM), grain size variations within the material microstructure can have a significant impact on its mechanical properties, thus affecting the integrity of the part. Being able to accurately measure grain size distribution throughout the build can be used to improve part strength and fatigue life. EWI has developed a grain size...
