Abstract

Some methods of the formation of microwelds, which are most acceptable for the assembly of 3D-wares with the use of wire leadouts, have been analyzed. Some peculiarities of the bonding of inner wirings on a die and a package by different welding methods, such as pressure welding with indirect pulsed heating and thermosonic, ultrasonic, and split-tip welding, have been considered. The effect of structural and technological factors on the quality of microwelds made by ultrasonic welding with the use of aluminum wire, aluminum metallization on a die, and gold, nickel, and nickel alloy coatings has been studied. Some information on microwelds made with the use of copper wire and copper metallization has been represented.
