WIPO Patent Application WO/2018/036202
Kind Code:
A1
Abstract:
Provided is a method for non-contact overall heating and tin brazing of a metal structural member and PCB, comprising the following steps: placing a workpiece on a drive system and transferring said workpiece to a heating system by means of the drive system, the workpiece being a joint body consisting of a metal structural member, PCB, weld, and a rotation fixture; heating the workpiece by non-contact thermal radiation of the entire body, causing the weld on the workpiece to melt; cooling the workpiece on which heating and welding has been completed, such that the molten weld rapidly solidifies into a desired weld point. The welded components are fixed, weld material is added, the weld is heated, and splitting is performed to establish two different processes, and a fine division of process steps is advantageous to the automation of each of the process steps, achieving modularized management.
