ABSTRACT:
For use in the fabrication of electronic circuit modules, there is provided a heating furnace which can be arbitrarily set in a desired temperature profile. The furnace includes a plural number of independently controllable heaters located in spaced positions to provide a plural number of heating zones in the furnace, and a plural number of cooling panels provided in the heating zones of the respective heaters. Each heater is independently controlled according to a specified type of substrate to establish a temperature profile for the specified substrate type in the furnace to carry out the curing of a sealing synthetic resin material of a semiconductor device and the reflow soldering of surface mounting devices in one and single furnace.
