Processes > Wire Bonding

Aluminum wire bonding is a process similar to gold wire bonding but with the key distinction that the surface does not need to be heated to 150C or even anything above room temperature. Ball Bumping Ball bumping is an important process in flip-chip applications as it provides the necessary interconnects between chip and substrate.

What is Wire Bonding? - TWI

Gold wire bonding is achieved through thermosonic bonding. This involves melting the end of the wire to form a gold ball, which is known as a free-air ball. The diameter of the free-air ball measures 1.5 to 2.5 times the diameter of the wire. After being formed, the free-air ball is placed into contact with the bond pad and pressure, heat and ultrasonic forces are applied to it for a certain ...

Gold plating - Wikipedia

Gold plating is a method of depositing a thin layer of gold onto the surface of another metal, most often copper or silver (to make silver-gilt), by chemical or electrochemical plating.This article covers plating methods used in the modern electronics industry; for more traditional methods, often used for much larger objects, see gilding.

Wire Bonding Guidelines - Cosemi Technologies

For a gold wire with a diameter larger than 1 mil(25µm), a cross groove on wedge foot is required to achieve a good bond. The extra mechanical ‘gripping’ action of the cross groove gives the tool/wire a higher ultrasonic interface coupling energy to the surface. For an Au wire with a diameter less than 0.8bond mil (20µm), a flat face is commonly used. Aluminum wire application commonly ...

In ball bonding, a capacitive discharge spark melts the tip of the wire and the surface tension of the molten gold forms the ball. This is called the “flame-off” process. The ball is then placed at the target bond site, and ultrasonic energy transmitted by the capillary scrubs the pad ...

Considerations Wire Bonding

1-mil diameter gold wire is a common choice, and has a resistance of 1.17 mΩ per mil of length, and a burn-out current of approximately 0.7 Å, de-pending on wire length, heatsinking, etc. Typical inductance attributable to a 1-mil bond wire is 25 pH per mil length, but varies depending upon bond wire height. Aluminum wire is almost exclusive-ly used in wedge-bonding applications, because the ...
