Figure 19. Gaiser capillaries are
manufactured with core angles of 10 degrees. The 10 degree core angle promotes good
looping, good transference of ultrasonic energy and allows for higher bottleneck of other
Figure 20. The 20 degree core angle
limits the obtainable bottleneck height and reduces the effective transfer of ultrasonic
energy. This is due to the reduced wall thickness as shown above. This limitation is
crucial for the fine-pitch tool designs requiring an angle bottleneck.
