What is Electrical Bonding?
Electrical bonding is the practice of connecting metallic objects that may be exposed to electrical faults or induced voltages to the grounding conductor. This ensures that in the event of a fault the current will have a low resistance path to take to trip the overcurrent devices as quickly as possible, as well as providing a path for static electricity and induced voltages to drain out. Bonding conductors must also be sized so that they can safely carry the largest possible load that might occur in a fault condition. Consult your local codes and regulations for how to size these conductors properly.
Why is electrical bonding important?
Another important use for electrical bonding is to reduce touch potential, especially in long runs of conductive cable tray. When voltage is applied to a conductor, be it a wire or anything else metallic, there will be some voltage drop across the length of the conductor based on its size, material, and length.

How to make a good ground connection?
There are a variety of ways to create a good ground connection, and they vary by country, region, and application . The most common types can include ground rods, plates, electrodes, or grids of buried ground wire. Even some non-electrical parts, like buried metal water or gas pipes, can be used as an in-situ grounding electrode in certain situations. To join the grounding conductor to the grounding electrode, special fittings must be used. They may be hydraulic compression fittings, mechanical lugs, or soldered connections. Codes will also state what size and type of conductor to use, and what combination of grounding devices may be used. Large facilities may require a network of grounding devices, wire, grids, and conductors to satisfy code requirements. Always check with your local codes and regulations to ensure that you are installing a safe and code-compliant system.

Very tight controls during processing enhance looping characteristics and eliminate sagging.
How many micrometers can a copper wire be wedge bonded to?
Copper wire up to 500 micrometers (0.02 in) can be successfully wedge bonded. Large diameter copper wire can and does replace aluminum wire where high current carrying capacity is needed or where there are problems with complex geometry. Annealing and process steps used by manufacturers enhance the ability to use large diameter copper wire to wedge bond to silicon without damage occurring to the die.
Why is heat used in metal bonding?
Heat is used to make the metal softer. The correct combination of temperature and ultrasonic energy is used in order to maximize the reliability and strength of a wire bond. If heat and ultrasonic energy is used, the process is called thermosonic bonding.
How does wedge bonding work?
In wedge bonding, the wire must be drawn in a straight line according to the first bond. This slows down the process due to time needed for tool alignment. Ball bonding, however, creates its first bond in a ball shape with the wire sticking out at the top, having no directional preference. Thus, the wire can be drawn in any direction, making it a faster process.
Grounding
Electrical grounding, also known as earthing, is connecting electrical equipment to the earth. The goal is to create a conductive path for electricity to flow in the event of lightning strikes, accidental contacts, static charges and surges.
Bonding
Electrical bonding is connecting multiple conductive components that are not intended to carry a current. This creates a conductive path between equipment, housing, panels, metal parts and other structures. In the event of an electrical fault or surge, lighting strikes or accidental contacts, electricity will flow through the bonded components.
