Although there is a thermal data testing function for our reflow oven, Bittele Electronics still uses a high-end, off-line, KIC thermal profiler as our key instrument for optimizing the reflow profile for every board.
These are the benefits of using an off-line thermal profiler:
The off-line profiler uses standard type K thermocouple connectors. It goes through the oven with target board. So, you don’t need to prepare long wires to connect each thermocouple.
It provides better data acquisition to precisely identify what is going on with each thermal profile and process in the production line.
Thermal profile data are conveniently transferred to a computer via a USB connection. So, a process engineer can analyze and check the data for solder joint quality easily.
Data Intelligence software such as Navigator Power is able to identify the best oven setup in seconds. A Process Window Index (PWI) is introduced to check if the profile is getting optimized -- the lower the PWI number, the more centered the profile is within the process window. A process engineer can use this result to manually adjust the profile easily.
