I agree with Russ. The problem is your thermal isolation is so small 1/16 inch. Also, most ovens measure temperaure in the plenum. You don't solder in the plenum. Therefore, you have a intermidiate "zone" temp. mixing between the top and bottom

I think perhaps you should revisit the choice and take another look at Universal Advantis, I-Pulse M2 & M4(low cost Assemblion), Samsung SM320 or CP45 Neo, Contact Systems C5, Fuji XP series, Juki KE2060, and Siemens Siplace. There is nothing wrong

Howdy aj, wow! Be prepared for serious problems with corrosion of your stainless steel workings of your pump. Last I looked changing a wave solder pot over to nitrated coating for electrovert was in the neighborhood of 18-20K. I'm not a betting man

Hi, Can anyone recommend a leadfree recipe for a BTU VIP98 i.e. which temperatures for which zones & belt speed? I appreciate that there will be a difference from one oven to another, along with different board sizes, but would like a good starting

I agree with "Two Cents" that the initial cost is very high, however, we may be able to justify with savings associated with improved layouts (high volume mfg)... so I am also looking into laser depaneling at this time. I have stumbled upon three co
