Editing the soldering profile in the [Profile management] tab and changing it permanently
– Vertical controller (top - bottom): Top heating/bottom heating percentage
power ratio. Adjust the power ratio to the heat requirement of your soldering
process.
– Bottom heating matrix field: Setting of each of the 4 x 4 bottom heating zones
with 0% – 100% values. The darker a field is displayed, the higher the set tem-
perature.
– To change the temperature of a heating zone: Highlight a heating zone by
clicking on it and overwrite the value.
– Methods to highlight several heating zones so as to change them all to the
same value:
Use the mouse to draw a rectangle over the heating zones.
Click on the right-hand or bottom blue side fields.
Switch off/on the lower heating with the blue field on the bottom left.
Use this function to reciprocally adjust the maximum value of the heating zones
and their ratio. For large PCBs, to avoid shape distortion, ensure that the whole
PCB is heated. Note that the components should not be heated too quickly as only
slow heating will result in uniform temperature distribution. This will increase the
safety level of the process.
To temporarily edit heating parameters, please read Chapter The [Heating setting]
tabulator under the [Rework] tabulator.
