K&S’s wedge bonding solutions deliver dependable, low-temperature ultrasonic connections, ensuring superior reliability for power devices, discrete components, and mission-critical electronics.



BRIEF OVERVIEW

About wedge bonding technology


Wedge bonding is an ultrasonic wire bonding technique that uses a wedge-shaped tool to bond wires into microelectronic and power electronics devices to create an interconnection between the chips and the package. This process is performed at room temperature and uses round aluminum, copper, or gold wires with sizes varying from 25 µm to 500 µm in diameter or rectangular-shaped ribbon wires for higher power density and high-frequency applications. Wedge bonding forms highly reliable interconnections, and due to its versatility and ease of use, it is used in a wide range of applications and devices, including power electronics, battery manufacturing, sensors, and instruments.
