Abstract :
The adhesion quality influence on the phase and amplitude characteristics of the thermal transmittance in the layered structures is determined theoretically and experimentally. The photothermal pictures of ultrasonic bonds, the galvanized lead frame, and the semiconductor chips soldered to the lead frame are presented and discussed
