The major profiler companies [ie, KIC, ECD, etc] give away FREE Excel spread sheets that list everyone's oven and paste and allow you to input board characteristics and then it suggests a profile. Go get one.

Q1: What are the basic requirements of thermal profiling? A1: Not sure what you�re looking for here, but when doing a profile, you�re trying to measure the temperature at specific points of the board, as the board moves through the oven. Q2: How we

Hello, I found the previous discussion of lead free profiles on 5 zone ovens very interesting. I had the same concerns, but have recently succeeded in creating profiles on a 5 Zone QUAD oven that have eliminated solder splatter or Solder on Gold w

For the lead free reflow process we tested with our Vitronics 500smr oven. To reach the high temperature of the lead free profile was no problem. We are not using an active cooling system so the pcb's are maby to hot wen the leaving the oven. Can an

| Hello all, | | Our guys here still have some questions on the "optimized" profile which sees a more moderate ramp up straight to reflow temperatures versus the conventional profile which has a plateau at around 150 Celsius. If the optimized profi

Here is what I would do faced with your problem. First I would profile a similar board or use an existing profile. From there I would place the dummy device on the surface of a sample board with a thin thermocouple soldered to the board surface under
