Although there is a thermal data testing function for our reflow oven, Shenzhen Grande Electronic 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.
