After a whole night's self review, I think we can term the slant/tilt as "floating 0805, yet end-terminals have acceptable solder joint formation". the width portion of the 0805 RES/CAP is (floating)elevated from the PCB pad, yet both (width) termin

There is two major BGA coating camps. * Camp #1: "We require the coating to be under low stand-off devices but with no filleting. So we apply a thinned dip coat first, and then top-off with a proper spray coat" * Camp #2: "We want no coating under th

That is the rub here, isn�t it? For those posting, it�s easier [but much slower] to start a new thread than to search the archives. [And posters could view their issue so unique and novel that it could never have been discussed several years earlie

A bit of gray area for you. consider the application over the specmanship. Why are the stiffeners there in the first place? Is the rigidity requirement a high function i.e. very necessary due to potential shock and vibration , etc.? The soldering is
