Hi. There is no problem with the exhaust system and the owen also has a sensor to messure the exhaust and would give an alarm if it stopped or went under a preset value. We have had our owens for one year now and the problem just started suddenly, we

Hello, If I do understand it correct, the dust in your oven are salt-crystals, comming from No-clean fluxes. We had them also once, it was a problem with one fan in the oven, I think you should check your fans inside the oven. Our extraction was OK,

Sure looks like flux residue to me and I don't know how your bare boards could be causing that unless there's something on them when you get them, and that you would notice. I'd still be looking at my own system, blowers and exhaust lines. Do any of

Recently I have been hearing and see this excess flux residue problem at several companies, US, Mexico, and Japan. It seems to have increased recently. In fact, it seems so common that it seems normal, but if everything is correct, a re-flow oven sho

Blimey just seen the picture that is bad. You could try to dissolve some of the residue/gunge in IPA if it is flux residue it should readily dissolve if it is resist issue then only portions will dissolve leaving a white powder which is Talc If you

We manufacture products that are double sided SMT (double sided reflow) and then have through-hold connectors attached to several of the sides. Currently we solder the connectors by hand, which works fine but takes a lot of time. I'm tempted to get a

Hi AJ, Change ALL 12 of the 1.0mm to 0.7mm. The CP 4 can only set nozzle size for S M and L not some of the 12 but all 12. 0402 usually come in 8 x 2 mm tape so you need 8 x 2 feeders or you will waste 1 component for every component you use. T
