How to Deal with Resonances in Wirebonding

Resonance effects can seriously impede or prevent wire bond formation. The two major kinds of
resonance are discussed: sharp resonances on eigenfrequencies and passive, following resonances.
Changing the ultrasonic frequency will remove the true resonance while the passive resonance is
independent of the US frequency and can only be cured by the right fixation of the bonded parts.
