I've never had this problem on an Omniflo oven, but have seen it on others. It has always turned out to be mechanical. A bearing going bad or FOD in the rails. I would pull the chains and carefully check each link of both chains, all of the bearin

We had the exact same problem on our OMNI 10. We found that two of the rails the pin chain rides in were warped. Somehow at one point our PC lost communication with the oven and the heaters went wide open for several minutes...this is what caused th

90% of the battle with thermal profiling is your thermocouple attachment. That is Process Engineering 101. It's just like painting your house. The masking and prep work will make or break the end result. KIC did a DoE on which thermocouple attach

Hi TMC, It's very unlikely that you'll get a temperature variation of 32 degrees by varying the top and bottom heaters - especially if it's forced air convection, as if it's a half decent system the hot air will be circulating in the zone, pretty qu

Hi smtspecialist (man I gotta get me a name soon), NO! Your oven cannot contaminate your process. Unless you have flux residues dripping on your board, there is nothing to worry about. Now having your operators switch from leaded to lead-free smo

Good for you smtspecialist and your clean oven. It's always better to be too picky, cause once the goo starts dripping, they'll only blame it on your paste. Mistress? No, gotta keep gender out of the work place. How about "Connoisseur Chunks"? S

I worked for a company that had an industrial nurse come in and talk to us about lead and saftey. Basically she told us in no uncertain terms that we had nothing in the facility that would come close to producing the temperature required to have lea
