Setting
Preheater 180℃,150℃,130℃
C/V 1.0m/min
Comparison with conventional preheater units
-Improvement in heating capacity
-Decline in inter-board temperature difference, ΔT,
owing to efficient heating |

A pair of box-construction cooling units are provided on the top and bottom so as to
enclose the base board. They combine to offer centralized cooling for the entire unit.
The cooling start position can be adjusted by sliding the top cooling unit in parallel with
the transfer conveyer and, by doing so, the parts mounted on the board are protected
against overheating effectively.
The sample profile shows that the upper and lower surfaces are cooled positively as
intended. |
