Hot-pressing welding is the pressure welding of metal wire and metal welding area by using heat and pressure. The principle is that by heating and applying pressure, the metal in the welding area will be plastically deformed, and at the same time, the oxide layer on the bonding interface will be destroyed, so that the contact surface between the bonding wire and the metal can reach the attractive range of atoms, thus attracting atoms and achieving the purpose of bonding.
