Call Heller directly, and give them the oven, and relative thermal density of the board, as well as the solder paste that you're using. They'll be able to give you a baseline profile to start from (both RTS and RSS). Otherwise, use a thermocouple p

Look to: * Your flux supplier's recommendations to baseline your recipe [similar to using your paste supplier's recommendations for setting your reflow recipe] * 7530 'Guidelines for Temperature Profiling for Mass Soldering (Reflow and Wave)' for gui

As we have vitronics oven(SMR610A) made in dec,1997,which has 5 heating zones and 2 cooling zones. For Lead free soldering what should be our baseline for low/medium boards.we have gathered profiles from various paste manufacturers,however we don't k

I have the same Heller 1500 and am about to start evaluating paste. Would you be so kind as to provide your oven set points to give me a baseline to start with? I think this would save myself and others a lot of time and effort ;-) Thanks James S

Get in touch with your paste manufacturer. They should have a data base of different oven types/zones, and can give you "baseline" settings for a medium thermal density board that has been proven to work well with their paste. After that, it sounds

This is a used oven, new to us. No product has been setup on it yet. We were establishing som baseline profiles and noticed that the actual profile read didn't even come close to our optimal profile. Further investigation proved that the belt was to

If your product mix is similar in terms of thermal mass and componentry, find some standard setpoints (by doing a baseline profile) which will produce a thermal profile that's within the specs. of your solder paste and product. This approach usually

I used to just follow up profile development with a single pass with a MOLE, one thermocouple in air. I'd keep that profile as a baseline, and have the operators run the MOLE through prior to production and compare the results to the baseline. I foun

Does anyone know of a SMT reflow modeling simulation that I could use as a baseline for reflow profiling? I'm looking for a quick means of setting up oven profiles for various oven sizes based upon board density (grams/sq in) and conveyor speed.
