Extended reliability of gold and copper ball bonds in

Wire bonding is the predominant mode of interconnection in microelectronic packaging. Gold wire bonding has been refined again and again to retain control of interconnect technology due to its ease of workability and years of reliability data. Copper (Cu) wire bonding is well known for its advantages such as cost-effectiveness and better electrical conductivity in microelectronic packaging.

Bond Lengths Introduction to Chemistry

Bond Length Values. Bond lengths have traditionally been expressed in Ångstrom units, but picometers are sometimes preferred (1 Å = 10-10 m = 100 pm). Bonds lengths are typically in the range of 1-2 Å, or pm. Even though the bond vibrates, equilibrium bond

Wire Bonding A Closer Look

1. The shape of the ball bond of the best wire bond supplier showed some interesting differences. Ball bonds made with the same size wire were consistently larger in diameter with more set down, see Figure 1. This larger ball diameter provided a significantly larger bond area and a potentially stronger bond. Figure 1 Ball bond shape. Note size
