That is an interesting idea. Would the air circulation increase the rate of oxidation on the component leads?

Is the prewash water going to drain or being re-circulated? If you are re-circulating don't send all or a portion to drain (or your treatment system) even sending a small portion to drain and adding fresh will reduce foaming. You will pull more water

In an oven with flux reclamation system, once the circulation is prevented by accumulation of flux in the heat exchanger, the flux will condense where it can, and some of it will coat your PCBs with a uniform layer of flux on the parts/ joints/ goldf

Consider: * Changing your temporary solder resist [TSR] to a light cure. * Contracting with your board fabricator to apply the TSR. * Gaining better thickness control of your application process by silk screening the current TSR. * Forcing more air c

Defects will result, Your cooling rate is affected because the hot air is not circulated properly. Outgassing will appear and you'll have pin holes / blow holes, disturbed joint etc. Correct me guys if i'm wrong. Thanks

We do the same, once you kill the power you lose your air circulation. I'm assuming it's not too good for the oven to have all that heat not moving.

bake the pcba, continue with the aqueous cleaning but after the cleaning bake them in a circulated oven. we do that with some of our pcbs here we use a water base flux, we clean it and then we bake them for 10 minutes at 190F

We've been using a newly installed DI re-circulating system. It's been a big headache. Mostly understanding what causes our resistivity to be unpredictable. I think I've got a handle on that part now. The system consists of a Carbon,HMR(chealet),Cati

Is this forum circulated throughout the U.S. only? I don't know where anyone is from when I read the replies. Is there any way we can get everyone to put at the bottom of their reply where they work and what city/state its in (or at least which cit
