Abstract
The method and apparatus employs a frequency sensitive electric motor and control system to measure the adhesive bond between a carrier tape and a cover tape adapted to carry miniature components. The adhesive bond strength is dynamically tested and recorded by separating the cover tape from the carrier tape as an energizing signal of predetermined frequency is applied to a frequency sensitive motor for a predetermined period of time while the force required to cause adhesive bond failure is measured and recorded.
