Heller Oven comes with a profile pre-loaded so you can start there. RTS = Ramp to Spike. Basically a straight line from preheat to spike. Also known as “Tent” profile RSS = Ramp Soak Spike. This one creates a flat line around 150-180 degrees on th

No problem . . . I have been throught this road before. Here is another heads up, if you ask for "thermal profile data" you can get the following: 1. a graph showing several thermocouples reading air rather than board temperature. 2. graph where e

I would suggest you do the following: get a sample / scrap board that you will be reflowing, attach thermocouples at various locations on the board, send the board to APS or whomever. Ask them to run a profile based on your solder pastes manufactur

For the ovens you run the profiler and you compare graphs. For the AOI you should run these golden boards(boards that you keep for AOI test - might have intentionally implemented defects) once in a while and make sure you are getting the same results

If you spent alittle more time on your bar graphs/time lines and less on the floor, the answer would be obvious!

Hi, We run a profile check each time we load a recipe. This ensures that the correct settings have been used for the job. It also gives traceability in the event that you need to prove whether or not the oven temperature was the cause for failed pro
