Abstract
Abstract An ultrasonic adhesion/dehesion monitoring apparatus for monitoring the adhesion/dehesion between first and second substrates comprising: a. an ultrasonic source for transmitting ultrasonic energy to at least first and second substrates; b. means for measuring the instantaneous AC current and instantaneous AC supplied to said ultrasonic source; c. means for multiplying the instantaneous AC voltage and the instantaneous AC current to determine the instantaneous power supplied to said ultrasonic source; and d. monitor means coupled to said ultrasonic source and said power determining means for monitoring the instantaneous power supplied to said ultrasonic source. Also disclosed is a method for monitoring the quality and/or adhesion/dehesion between first and second substrates in the ultrasonic adhesion/dehesion monitoring apparatus.
