We've got 2 lead free lines running at present and one leaded. Our lead free pallets and stencils were both leaded before changing over. Just take care to remove any built up flux from the pallets as well as hidden leaded solder deposits prior to r

Hi Lloyd (did I just stutter?), While I do love Steve's response, I must add that solder is not a very strong metal. And technically, it's sole purpose is to provide an electrical connection. It's a bad choice for mechanical connections, yet every

LOL! Well I do make the BIG bucks - 8.5 by 11 in size, but our Hi-Scope is the same one Abe Lincoln used in the Civil War. It's old, but does the job. I've had my share of Q.E.s using every thing imaginable to mechanically test the solder. Althou

We just got new boards in that have ENIG pads. In the past we had a problem with too much gold getting into the wave solder pot from large connectors getting tinned at the wave. Do we have to worry about too much gold getting into the pot with this

Folks, we've recently upgraded to Heller MKIII reflow ovens with Gen 9 cooling units. We're running N2 atmosphere at 1000ppm O2 and Kester256 solder paste. We're seeing a big problem with flux residues building up in the cooling section of the

Good afternoon, Oops. Quite huge difference I must say. But you should try to tweak your profile anyway. First of all try to enlarge soak time as Mr. RDR has said. What process type do you use? Lead or lead-free? By the way, there are lead-free proc
