Wedge-Wedge

wedge-bonding
with 25µm gold wire

Ultrasonic Wedge Bonding or US Bonding is used for bonding gold or aluminum wire. For power applications, copper wire can also be used. There are three different kinds of wire bonding: Thin wire bonding or just wire bonding with wires from 17 µm up to 75 µm. Heavy wire bonding with wires from 100 µm up to 500 µm. And ribbon bonding with flat-band ribbons of different sizes.

Ball-Wedge

ball-bonding
with 25µm gold wire

Thermosonic Ball Wedge Bonding or TS Bonding uses a combination of heat, pressure, and ultrasonic energy to create a weld between a gold, copper or silver ball and the surface of a chip. A gold, copper or silver wire is threaded through a capillary made from ultra-fine ceramics on which tip a high-voltage electric charge is applied to the wire. This melts the wire into a ball, called flame off. With pressure (bond force) and ultrasonic energy the capillary connects this ball now to the surface of the substrate. After that a loop is formed and a second bond applied in the form of a wedge bond, also called stitch bond.

Ribbon

bonding
with ribbon

Ribbon connections are low in impedance and have a considerable heat dissipation. Due to these characteristics ribbons are frequently used in radio frequency (RF) technology.

Bumps

bump-bonding
in flip-chip applications

Bump bonding is used for flip-chip applications: mounting a chip up-side-down directly onto a substrate or second chip. No additional wire is used, and the contact is established solely by beforehand applied bumps. This method is very compact and low in inductance, due to the short conductor lengths. Furthermore, it is possible to stack multiple chips on top of each other.

copper wire

Zur Vorbereitung einer Serien Produktion oder für Spezialanwendung kann es nötig werden von den gängigen Materialien Gold und Aluminum auf Kupfer auszuweichen. Hierbei gibt es zwar ein paar Besonderheiten zu beachten aber die Vorteile sind ein günstigerer Drahtpreis, bessere elektrische Leitfähigkeit und bessere Wärmeleitfähigkeit.

Coated

bonding aluminum
coated copper wire

Kupferdrähte besitzen beim Bonden ähnliche Eigenschaften wie Gold, müssen aufgrund der Oxidation jedoch unter Schutzgasatmosphäre gebondet werden. Wegen dieses Aufwands werden Kupferdrähte nur bei besonderem Bedarf eingesetzt. Eine Alternative hierzu ist das Bonden mit Kupferdraht mit Aluminiumbeschichtung. Dieser lässt sich einfach Wedge-bonden und ist gut lagerfähig.

Insulated wires are short circuit proof due to the full insulation of the wire. Insulated wires are usually soldered. In some cases connecting the wire with a bonder can be a viable alternative.
