Description

technical field

[0001] The invention relates to a processing device and a processing method using thermal energy and the equipment produced therewith. Background technique

[0002] In conventional processing equipment, after the workpiece is placed in a heating furnace (hereinafter referred to as reflow furnace) heated to a necessary temperature, the joints of the workpiece are assembled and welded (hereinafter referred to as reflow). Or use the heat generated by light bulbs or laser light sources for solder joints.

[0003] When putting parts with different heat-resistant properties, special-shaped parts, and parts with different colors to be processed into the reflow furnace for reflow, because the weak heat-resistant parts are burned, damaged or deformed, such parts cannot be processed. The processed object is put into the remelting furnace for remelting.

[0004] In addition, for a workpiece whose initial temperature rise time and temperature are to be changed in the r...
