I had a solder paste SAC305 T4, with flux loading of 11.5%. After retrieivng out from fridge(5deg) after 48hrs, the paste turn dry (like dry mud? and after double checking the flux loading it becomes 12.5%. Has anyone ever experience this or any opi

8.4 * SAC305 => 7.36 * Sn-3.5Ag => 7.5 * '....in' [96.2Sn-2.5Ag-0.8Cu-0.5Sb] => 7.39 * Sn-4Ag-0.5Cu => 7.39, 7.44 * Sn-3.8Ag-0.7Cu (Multicore solder) => 7.5

We evaluated the OM338 from Alpha and it worked great! Looked like crap, though, compared to the other products out there. When I set the boards out in front of the Alpha sales guy to show him the difference in appearance between his boards and the

Last week I had the opportunity to get a sample of AIM SN100C solder paste. The SN100C paste was very nice to work with. My initial observations was that the paste had a very light odor, much less than the Alpha UP78 paste that we are currently

Maybe this piece of information will help. In China (just returned from visit) there are many factories that are using a dual temperature process using SAC305 or Sn100C and 42/58. Apparently this allows them to run their through hole parts through re

Multiple process and rework thermal cycles are brutal on boards and components. Improving reliability of products through reducing thermal stress ends-up being a major driver to the interest in lower MP LF solders. Binary LF solders require the addit

Billy, I have to disagree with you. We inadvertently soldered a Pb BGA with SAC305 paste and then had it micro sectioned and spectrum analyzed. Imagine our surprise when we saw the spectrum analysis showed Pb. The micro sections showed none to ac

Hey all! As background, I recently purchased a full SMT line for my company. We have a DEK 265, an assembleon opal xii, and a Heller 1500. Currently our jobs are leaded, and the heller is working perfectly. An upcoming job that we are potentially g

Now I've checked the archives on this and found the starts of an answer but not much else, but then that posting was a while ago and I though there would be some more data now. So here's the question: who, if anyone is placeign Pb-free BGA's (ideally
