After finishing modifying working mode, if you want to modify laser alignment mode, operate
as D item shows; if no need to modify it, please press DOWN key to browse the next
parameter
settings.
C-1. Modify Parameter of working flow
If it is necessary to modify parameter of a working flow, first you must select the working flow
and then modify its parameter.
The soldering technics is decided by T0, TB, T1, T2, T3, S1, S2 and S3. It describes the
temperature graph during the system working. TL denotes Melting temperature of solder and
the range between T2 and T3.
T0
T0 is the valve temperature for bottom heater required by top heater when it heats up. Also it is
the first temperature of this technics process. When the work flow begins, the bottom heater
starts to heat up. After reaching the T0, the top heater begins to heat up.
TB

Tb
、
TC
TB: The test temperature of bottom preheating Tb: set temperature of bottom heating TC:
Real-time temperature of top heating
T1
It is the heat preservation starting temperature of reflow soldering. It is the second temperature
of this technics process. The temperature rises to T1 with a proper speed the component permits.
In parameter modifying, use the UP and DOWN knob to set the value of T1.
T2
It is the temperature when finish the heat preservation of reflow soldering. The pre-heating
temperature rises to T2, after the time of S1 finishes. Within this time, PCB and component
pre-heating is finished and the solder is activated. In parameter modifying, use the UP and
DOWN key to set the value of T2.
T3
It is the peak value temperature of reflow soldering. When the temperature reaches T2, the
temperature equably rises to T3 with a definite raising speed. The soldering or de-soldering will
be finished when the temperature reaches to the peak value and performs the next step. In
parameter modifying, use the UP and DOWN key to set the value of T3.
TL
Melting temperature of solder. At this temperature, the solder starts to melt down and turn into
liquid.
During the soldering and de-soldering, users can press CAL Key to calibrate the value of TL
when the solder turn into liquid. In parameter modifying, use the UP and DOWN knob to set
