REFLOW TRACKER Reflow Temperature Profiles 25
WARNING
Take care not to trap fingers when closing the barrier lid.
Placing the System in the Oven
1. Place the instrumented PCB on the oven’s conveyor with the thermocouple
cables towards the rear.
2. As the board travels
towards the oven feed
the thermocouple cables
carefully, ensuring they
do not foul the oven.
WARNING
Never allow
thermocouples to touch
an oven’s heating
elements. This could
cause major injury
or death.
3. Load the logger and
thermal barrier onto the
conveyor some distance
behind the PCB to
ensure their thermal mass does not affect the PCB’s heating and cooling. If
the oven has an edge conveyor, place the thermal barrier on a carrier plate.
Removing from the Oven and
Downloading Data
Recover the system from the oven as soon as the run is over.
WARNING
The thermal barrier and logger will be hot enough to burn skin – even though
their temperature will not be apparent. Use protective gloves.
Failure to remove the logger quickly from the hot thermal barrier could
damage the logger.
Do not remove the logger by tipping it out of the barrier. This can lead to injury by
dropping the logger onto your body, and may damage the logger.
