Wire bonding is a method of making interconnections between an integrated circuit (IC) or other semiconductor device and its packaging during semiconductor device fabrication. Wire bonding can also be used to connect an IC to other electronics or to connect from one printed circuit board (PCB) to another, although these are less common.

In semiconductor device fabrication, the various processing steps fall into four general categories: deposition, removal, patterning, and modification of electrical properties. Deposition is any process that grows, coats, or otherwise transfers a material onto the wafer.
Glob-top is a variant of conformal coating used in chip-on-board assembly (COB). It consists of a drop of specially formulated epoxy [4] or resin deposited over a semiconductor chip and its wire bonds, to provide mechanical support and exclude contaminants such as fingerprint residues which could disrupt circuit operation. It is most commonly ...
Wedge bonding is a kind of wire bonding which relies on the application of ultrasonic power and force to form bonds. It is a popular method and is commonly used in the semiconductor industry . Wedge bonding is directional, so the bonding head rotates to accommodate the different angles for bonding.
Location of Sri Lanka. Sri Lanka is an island country located southeast of the Republic of India and northeast of the Maldives.According to the International Monetary Fund, Sri Lanka's GDP in terms of purchasing power parity is second only to the Maldives in the South Asian region in terms of per capita income.
The resulting weld is quite different in appearance from the ball bond, and is referred to as the wedge bond, tail bond, or simply as the second bond. In the final step the machine pays out a small length of wire and tears the wire from the surface using a set of clamps. This leaves a small tail of wire hanging from the end of the capillary ...
