| - | ====== Bonding ====== | ||
| - | |||
| - | Bonding is the process of connecting bond wires to bond pads. | ||
| - | |||
| - | ====== Ball bond ====== | ||
| - | |||
| - | This is the most common and cost effective method for general use on modern ICs. It works by using electricity to spot weld the wire to the pad and may also rely on pressure, ultrasound, and heat. | ||

| - | ====== Wedge bond ====== | ||
| - | |||
| - | {{gallery> | ||
| - | |||
| - | This uses only ultrasound, pressure, and heat to connect bond wires to ICs as opposed to ball bonding which also uses electric current. As it is slower than ball bonding, it is only used now for special high speed applications. However, it is common in older ICs. | ||
