Hi, That's a really interesting article, however one thing I am a little confused on. They seem to say a Pb-Pb solder joint is almost as bad as a Pb-lead free joint in their results. Are they saying the testing which looks like it cycles up to 125 D

We all know those academic 'reliability studies' are very focused and only give a snapshot of real life. The real reliability studies of leadfree are starting as we scramble to meet our numbers. We have no idea about your customers' expectations ab

Hi, That was another very interesting article posted. This article seems to point to the same conclusion, which is that lead free soldering is more reliable than Pb components with Pb paste, and Lead Free components with Pb paste? From what I see,

It's hand solder, the wires are free issued, what i'm finding is that if we keep the heat and push enough solder into the joint that the component side wets there is that much solder moved up the wire that it goes solid. this is no good as the custo

Hi Dallen, I do not know BTU VIP70 oven, any way make sure if it is not yet wired for 480 V 3Ph (wiring diagram), may be it needs just to reset wiring on terminal block in order to run at 480V. Best if you ask BTU. If not, you have to buy a Transfo
