Quick Start Up Guide
- For each phase set the heaters power, the actual
temperature reading is the input for control to drive
the heaters according to the user setting to finish
each stage. The Control will achieve the TAL (time
on peak) according to the last stage heaters power
setting. Control might fail if user set the heaters
power level lower than 50%.
- After finish the process profile settings, profile can be
RUN, Save to PC or Save into machine memory. The
available profile number will automatically be shown.
RUN Process Profile on RE-8500
- Before the process running, Set the process Graph
parameters length for the graph in time, maximum
Temperature scale, temperature scaling method.
- Set the Automatic cooling after Process Finish
- Confirm the Safety temperature Value
b. Standard profile
The Standard profile designed to meet the IPC original Reflow profile
recommendation as Follow:
Preheating with slow heating ramp up not less than0 .5℃/second
Soaking with heating ramp up not more than 1.5℃/second
TAL: Time above melting point (liquidus) available in time from 1second
to 60seconds
Dark Infrared heating technology is not driven by ramp and it is sensitive
to working environment and Air flow.
The standard profile whether for Leaded or Lead free solder materials is
driven by controller PID control. The standard profile parameters only for
profile phases end temperature. Then the control will completely drive the
heaters powers to achieve each phase temperature ends.
