How does hydrogen bonding cause capillary action? - TimesMojo

WebIn wedge bonding, a stub of wire is pressed against the bond pad by the foot of the capillary, applying ultrasonic energy to form the bond between the wire and bond pad. The capillary is then moved to the second bond location and the process is repeated. Once the second bond is completed, the wire is clamped and snapped above the second bond. WebSome common features in all ball-bond equipment designs include a wire clamp positioned above the tool (capillary) and a wire that feeds through the center of a ceramic capillary (tool). Figure 1 illustrates both wedge and ball bonding. Automated wire bonders were introduced in the early 1980s. gita bhawan public school moga
