  • Wire bonding capillary with bracing component
    Patent number: 5944249
    Abstract: A capillary (22) for use in wire bonding is provided. The capillary (22) includes a tubular body (24) having a longitudinal axis (AA). At least one notch (42, 62, 64) is formed in the tubular body. The angular alignment of the capillary (22) and capillary face (42) correspond to the angular position of each notch (42, 62, 64), thus allowing the position of the capillary face (42) to be controlled by inserting the capillary (22) into a capillary channel (44) having a wedge (32) that mates with the notch (42, 62, 64).
