Apply more kapton tape to ensure good contact between the thermocouple tip and the PCB
Place the prepared PCB in the reflow oven, route the thermocouple cable out of the drawer at one
side and fully close the drawer. Ensure the PCB is placed underneath the thermocouple mounted in
the front of the oven. Plug the thermocouple into the thermocouple socket on the side of the reflow
oven.
Run a test cycle and observe the temperature profile of the PCB. Make adjustments as necessary to
the profile settings after each test profile, repeat until the profile temperature measured on the board
is suitable for your parts and solder paste recommendations. Ensure the maximum temperature for
the most sensitive part(s) are not exceeded.
Profile testing can be carried out by carefully watching the temperature reported for the PCB
thermocouple, or by logging the data via the USB port and using the ESTechnical reflowViewer
software (see below). Alternatively it is possible to use an external thermocouple meter to monitor the
PCB temperature. Adjustments should be made to the profile settings based on the observed
temperature of the PCB.

temperature settings, consider carrying out
Data Logging – ReflowViewer Software
ETechnical provide a simple live data graphing application for use with the reflow oven, this aids
adjusting profile settings and helps reduce the number test cycles performed for each design. The
software allows easy adjustment of the reflow profile settings stored in the oven controller.
