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

They may tell you it will solder lead free,(and it may) but trust me...you are going to have nothing but headaches. If you start flooring the heaters you are going to put it into a "melt down" after a while. I know you don't want to hear it, but tak

One more thing I want to add. Don't turn this into some big deal. Its not atom splitting, or black majic.Bottom line is that you are going to be doing some experiments to prove it to yourself and whomever else requires the data. Profiling is time con

Thanks for the info Dave. Yes it is too bad on the solder connection appearance discussion. I figured that posting would spark a flurry of responses. Don't take me the wrong way I am aware of your credentials, I just wanted to point out what my expe

Hello Danial, Leave it up to most to blame the relow oven for their tombstoning problems when in fact it is usually the last to cause it. The biggest culprit of tombstoning is the pad design followed by the print quality. Usually, we find that the p

Robert, what you have provided is not a "profile". It is a "recipe" or "job". I have 4 BTU VIP98's. I have hundreds of recipes...Your temps look similar to mine....but what does that have to do with the "thermal profile" as experienced by the asse
