Stephen, In addition to your comments The bothersome part is that NO environmental impact assessment report commissioned by the EU on the environmental impact of lead in solders and its alternatives exist. The two environmental impact reports that

Howdy, I have an Electrovert econopak smt II. I'm set to change over in June to SN100C. I won't be changing out anything. I'll just be purging the lead out of the solder pot with a tin bath. I don't expect there to be any problems with our change

Its it possible to post a picture from right after reflow? To see what we start with and compare the difference after 5 years. The grainy structure is not as much a concern as the growth-like appearance on the boundary of the solder. What paste al

That is the problem I am having! Except with 3 separate manufacturers. To answer some of the other questions... Baking - diligence Stencil - as far as we can tell it is good Placement is good We are using Pb-free parts and solder, but I have see

If the only difference is the layer count, check the profile as stated above. If you dont have a profiler you can probably get the local Kic or Mole rep to do a demo on that board. I believe I was the one who stated in an old post that prying the lea

Yes, leadfree paste is dispensable, but there is a completely diffrent paste than one will use at the stencil printer in the line. This is a very tricky one to deal with. We use xxx lf-free paste in the line, but that paste will Not at all work at th

Thank you all for your input. The MF300S Multicore flux is rated for lead free. There is not much dross or contamination. We are using nitrogen. I've tested the boards with the curing test of IPC-TM-650. I think you're all right about the preheat.
