I have the same Heller 1500 and am about to start evaluating paste. Would you be so kind as to provide your oven set points to give me a baseline to start with? I think this would save myself and others a lot of time and effort ;-) Thanks James S

Jay - I read your report and was interested to see that you ran your evaluation on a Heller 1500 5 zone. We have been hearing for some time that a larger machine (7 zone min)with higher temp heaters and fan motors would be required. Is yours a "hi t

Hi Scott, My Heller is a bog standard Heller 1500 with an edge guide. There is nothing special about it. I would of course love to have a 7 zone oven, but...I have to use what is here at this time. My only concern with a 5 zone oven is the change i

Today, I have just finished evaluating Kester's EM907 (SAC305)lead free solder paste and found that for our applications it performs as expected. End result that I am encouraged with the results that we got. The equipment that I used: An SMT2020 to

Presumably you're talking about lead free, but you don't say. Heller can probably provide you with a starting point, as rob has already pointed out, but you do need to develop the capability to perform profiling yourself. That oven should have ECD

I set up some lead-free profiles on a new Heller1700xxx (Compact series), do not know if this is same model you refer to. Can be done, yes speed is a little slower than longer Heller Versions due to zones being so narrow, but doable. Of course all de

I am looking for some advice. My company is thinking of upgrading our reflow oven. We have looked at the Heller ovens, in particular the 1800W. We are lead free. Is there anyone that could share experiences, or first hand knowledge of these units.

Danny, with the Heller 1800 series oven, what is the standard oven profile for lead free. I am having some proble profiling boards with BGA. I am getting alot of voids. If you have a profile for a Heller 1800 nine zone, could you please send me a

As a solder paste supplier I have profiled lots of different makes of ovens. I really like the Heller 1707. I have several customers who do lead free mid volume assembly with these ovens. They also seem to give shiny lead free joints.

Craig, We currently have an older Heller 1800 and quite like it in production. It easily handles our lead free products, and has enough flexibility to handle both heavy boards and lighter boards. Thermal profiling is relatively easy. I'm told the
