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

Common Causes of Wire Bonding Failures . Wire bond failures comprise a major concern of any semiconductor manufacturing company. Common causes of wire bond failures include the following:. 1) Voiding in the Bonds Atomic interdiffusion between different metals is a natural phenomenon in a wirebond metallurgical system. If left unchecked, however, this can lead to voids in the bond that can

A wire bonding method includes aligning the face of a capillary along a first direction to make a first wire bond at a first bond point.

Capillaries are tools used in wire bonding machines to connect IC chip electrodes and lead terminals with wires. Our company designs capillaries according to bonding specifications,

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.

Low-K Wire Bonding Capillaries The process for low-k device bonding is very sensitive especially for ultra-fine-pitch bonding. In fact, the most challenging problem with low-k wire bonding is ball bond reliability. A polymer-induced bonding problem occurs when the bond pad is small.

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

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

Common problem associated with copper wire bonding and bonding on NiPd plated leadframes and QFN packages are poor bondability on the 2nd bond. Dou Yee has developed the HMX Capillary with the objective to improve the bondability of the stitch bond through better coupling between the capillary and the wire during bonding. Its HMX proprietary

Smallest bonding pitch: 25 μm using 18–20 μm diameter wire.Chip–chip assembly: Bond capillary touches bond pad during second bond, making this method unsuitable for chip-tochip bonding (risk of pad damage). However, there are workarounds like the use of stand-off-stitches, basically requiring a bond-stud to place on the second pad to

The situation can be improved by incorporating the laser vibrometer as a monitoring system to study the ultrasonic displacement of the capillary during wire bonding. Optimization of a 60-μm-BPP process was performed on an ESEC wire bonder, and the defined process window was bond power=8.4-10% and bond force=140-170 mN.
