Оптимизация режимов ультразвуковой сварки алюминиевой проволоки с золотым гальваническим покрытием 3D изделий

Considered design and technological features of the formation of high-quality compounds, aluminum-gold in semiconductor manufacturing, including 3D devices. Optimization mode ultrasonic welding of aluminum wire with a diameter of 35 microns to gold plated with 3 microns of packages. The maximum theoretical strength of connections Al-Au is defined under the following conditions applies: 25 ms (welding time); 30 cN (compression force); 30 (power ultrasonic inspection in relative units)
