For now, on this first board, we will be reworking components such as 0805 and 1210 size caps and resistors, along with SOT-23 and SC-70 size packages. We might eventually get into BGAs. This board will most likely be a double-sided board, probably

Steven, Try http://www.document-center.com/home. You will find various standards for BGAs freely-available but not for free. BTW, I have never seen a BGA underfilled. Only FC and CSPs. The standards available will explain when to.....High CTE delta

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

Well put, Evtimov! :) I've made my argument against it. I'm not comfortable taking a job placing parts outside the capabilities of the machine in general, much less parts that I can't actually see! The machine is good down to .5mm pitch parts, and

Heat guns used improperly will definitely damage components. You must have a controlled heat gun that can be set to the max temp you want pb =215C max, Pbfree maybe 240C max. This heat gun must not be able to be adjusted or you must have total trus
