ATMOSPHERE CONTROLLED JOINING DEVICE, JOINING METHOD, AND ELECTRONIC DEVICE

摘要

This invention provides a joining device for pressure welding a pressure welding part that can realize pressure welding under low temperature and low pressure conditions by rendering the moisture content of the pressure welding part atmosphere within the device relatively smaller than the moisture content of the atmosphere outside the device. In this case, the amount of water adsorbed on each surface of a joining metal terminal and a metal terminal to be joined constituting the pressure welding part is brought to not more than 1 x 10^16 molecules/cm2.
