The extra steps that manufacturers need to take to ensure quality can be costly and time-consuming – not to mention the possibility of introducing other problems like distortion and waste. EWI has developed and tested several new methods that are now being...

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...
