Block hot plate (14) is fitted, and to-be-welded pieces (18) begin to warm up, and after reaching the default heat time, stomata (10) discharges into nitrogen again,
To-be-welded pieces (18) floating again, rotating disk (8) continues to be rotated by former direction；
D. repeat step C, to-be-welded pieces (18) by heating and thermal insulation of being fitted with each hot plate (14) in temperature-varying zone (3) successively,
Realize the requirement of different heating curves in solder reflow process；
E. when to-be-welded pieces (18) reach discharging area (1), to-be-welded pieces (18) are by falling stock chest (15) under Action of Gravity Field in,
The limiting plate (16) for being now placed in discharging area (1) is sky, treats that limiting plate (16) rotates to feeding area (2) again from discharging area (1)
When, continue to repeat step C；
F. after stock chest (15) is piled or to-be-welded pieces (18) have all been put into stove, operating personnel take out from stock chest (15)
Finished product weldment.
