Without forced exhaust your oven will struggle to regulate zone temps, especially if a cooler one next to a hotter one. There should be no damage to the oven, just working harder to regulate itself.

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

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

Bi monthly?!!? What are your exhausts getting clogged with? You have that much dust in the air that cleaning every two weeks is necessary?

The solder problems that were created caused overcompensation. Plus our PM schedules could be monthly, could be yearly depending on the maintenance crew for a particular line.

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

We had a vent block up not too long ago ourselves. Saw multiple solderjoints, especially on fine pitch micros, that looked like they had alligator toes. We solder bump, so it was obvious that area didn't get hot enough to liquify the solder and hav

Hi All, We are gathering information on the environmental conditions in our facility, including the fresh air exchanges. A driving factor is any point of exhaust that goes to the outside air and the CFM that it pulls from the facility and if there

Please read your manual, I am sure that it will address proper maintenance of your oven ducting and flux build up. The MFGR will also be able to specifically address your problem and let you know if any upgrades are available. Flux collection filter

I just purchased a used Heller 1500 reflow oven for an SMT line that I am ting up. Looking for the CFM requirements for my exhaust venting. Does anyone out there have any information on what the minimum requirements are for pumping this exhaust out
