Abstract:
An apparatus for manufacturing an electronic circuit substrate by hot-melting bump terminals of a solder material formed on an electronic device to connect surfaces of the electronic device and of a circuit substrate to each other, said apparatus comprising a treating vessel adapted to receive therein said electronic circuit substrate, pressure control means for controlling a pressure in said treating vessel, heating means provided in said treating vessel, transfer means for transferring into said treating vessel the electronic circuit substrate, in which said electronic device is temnorarily fixed on said circuit substrate by means of an alcoholic solution supplied in a manner to cover the connecting surface of said circuit substrate and the solder terminals on said electronic device, and apparatus control means for controlling an evaporation rate of said alcoholic solution for solder bonding by permitting said heating means to heat said electronic circuit substrate transferred into said treating vessel by said transfer means and permitting said pressure control means to control a pressure in said treating vessel.
