wire bond capillaries

A capillary has a face surface 13 formed at the tip end thereof so that the face surface 13 inclines toward the center thereof so as to have a tapered shape, and has a through hole 11 formed therethrough so as to permit wire to be placed therethrough so that the through hole 11 has an opening 12 at the center of the face surface 13.

Wirebonding equipment use bonding tools known as capillaries for thermosonic ball bonding. Capillaries hold and control the bonding wire as well as form bonds from it during the ball bonding process. Capillaries are ceramic axial-symmetric tools with vertical feedholes (holes where the bonding wires are fed) through its center. Fig. 1.

A gold wire passes through a ceramic bond capillary (a needle-like tool). Then a high-voltage electric charge melts the wire, creating a gold sphere (free air ball, or FAB) at the end. Next, the free air ball forms at the tip of the capillary, and the tool moves sideways to a position above the required bond pad on the device which is placed on

In 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 repeat- ed. Once the second bond is completed, the wire is clamped and snapped above the second bond.

tip radius of the capillary, and increase in Young's modulus of the wire. These study results verify the feasibility of wire bonding at pitches of 70.

A multiple face angle wire bonding capillary of the present invention has an elongated hole therethrough terminating at one end of the capillary tip, 

Thermosonic Wire Bonding is performed using ultrasonic energy, pressure, and heat to bond a wire to the surface of a substrate. In this process, the capillary is not heated and the temperature of the substrate is maintained between 100 to 150 degrees. A burst of ultrasonic energy makes the bond.

Capillary unplugging wire offers an easy economical way to unplug clogged capillary. This is especially useful for engineers during bonding evaluation when the optimum process parameters are not defined yet and the gold ball tends to get clogged in the capillary holes. This can be done by simply inserting the tip of the unplugging wire from the

Wire diameter is a key factor in determining the appropriate hole size of the capillary. An optimal hole size is essential for a successful 

Wire bonding ranks among popular and dominant interconnect technologies due to its reputation for versatility, performance, and reliability. In this type of bonding, the capillary does not contact the pad surface. For the second half of the bond, the capillary is moved to the location for the stitch bond. Here, the capillary rests against

The loop profile significantly influences the reliability of wire bonding, and it is necessary to study the wire bond looping process. The loop profile of the bonding wire is determined by the tension and material property of bonding wire as well as the trace and structure of capillary, in which the capillary trace has a major impact on the
