Scanning Electron Microscope (SEM) image at 5000 X magnification of a laser bond with about 800nm of weld penetration into the bond pad. The Laser Ribbon Bond (LRB) cross section shows precise penetration control.
This is a laser bond magnified 300 X.
Shows the side-by-side results of fatigue tests done on the ultrasonic wire bonds vs. laser bonds. The results shown of this test demonstrates the fatigue life of the laser bond that Interconnects, is several orders of magnitude better than comparable ultrasonic aluminum wire bonds.
