Well the profiler IS out for calibration so I can't use it. However, what piqued my curiosity is your statement concerning uneven heating. On the product we were running we had several non-liquidous solderjoints where as the rest of the joints looke

Your oven no doubt compensated by reducing energy to your heaters so it might not be as bad as you think. I'd be more concerned about even heating than over heating. My opinion is that an out of calibration profiler result is better than no result

I just discovered my reflow oven exhaust had no suction and I'm fixing it now. What I want to know is what happened to my process. FYI. The exhaust from my other oven was getting kicked back into the faulty oven because of this loss of suction. The

You may not be getting enough exhaust pull, so the cooling modules over temp. Try swapping blower motors to isolate that before buying one. STANDARD AIR OPERATION: - Load-end: 150 cfm (255 m3/hr) at the 4� (102 mm) stack (minimum requirement) - Unlo

Thanks This error only occurred with one oven profile with the reflow zone temperature set at 270�C. Perhaps it really has to do with the exhaust pull as the oven is operating very near its temperature limit with this profile. I will check that. Tha

Hello all Our Omni 5 has given the 'Cooling module high temp' warning twice during the past month. I suspect that the blower motor is the culprit but have not been able to verify this because the oven has started up normally after acknowledging the

I'm inclined to believe along with others that if you don't smell it, and the flow rate is consistent (hence, your profiles aren't suffering from fluctuations in temperature due to fluctuations in circulation) you're probably OK. It does beg the que

Hi all. We recently expanded our assembly space and moved our Heller 1500 oven to a new spot. In the old arrangement, we used a Purex filtration unit, keeping the hot air in our space. Recirculating the fumes caused a massive headache in cooling the

The 2 issues are: -1 Enough flow to keep all fumes from reaching people. -2 Consistent amount of heat removal to keep the temperature steady. If the 45 CFM is steady and keeps all fumes away from people all is well. Jerry
