One of my customer had an oven made of galvanized metal. when he rised the temperature for lead free application the zinc from the alloy(blower turbine and housing,...) was melted and was removed .I offered to my customer an used oven tornado made by

Thanks, Dave, To the 183 TAL...I was just referencing a previous post I found in the archives. We checked the profile on the board this morning, absed on the temp info that AIM recommended, and found that we're above liquidous for nearly 2 minutes!

Thanks for the input guys. One problem with this theory, we see the same failure using Omni 5000 solder paste. We also see this problem across 4 production lines, suggesting it is not oven related. The profile meets recomendations and we have tried

To state whether an oven can or cannot "do lead free" very much depends on what type of product you need to solder. High thermal mass products are problems for 4 and 5 zones ovens becauase they typically cannot follow the solderpaste mfrs. profile, u

Hi If you mean your PCB stayed in the Reflow oven more than the reflow time required for the solder paste specs then I suggest to throw away the board because it would lead over heated solder joints all over the board. Think what could happen to an

I have recently been handed all responsibility of our Reflow Ovens. Upon my inspection, I discovered that any possible device on the ovens that you would think would require calibration, has a sticker indicating no calibration required. The practice

I recently inherited an APS GF-12HC reflow oven, which requires a password in order to access the profiles & run the machine. The individuals that operated the unit are no longer with the company and nobody else seems to know the password. Does anyon

I have accuired a Novastar 1800A Reflow Oven, But no Documentation. I am trying to alter the profile of the machine, but cannot access the setup menu. The screen says enter the security code to continue. Does anyone know what the security code is for

Is your oven suitable for Lead free temperatures & can it achieve a decent profile across your complete range of boards? AOI will need to be looked at too as the joints are not as shiney. Cheers, Rob. PS. Where's Thisbie?
