If the solder joint meeting 8.2.5.4, minimum side joint length(D) and also meeting 8.2.5.6, minimum heel fillet height (F) but the heel fillet NOT extend to the mid point of outside bend. It is acceptable?

We'd say yes, if it meets both 8.2.5.4 and 8.2.5.6

Hi aram, Hot air is best. IR takes longer and is affected by the color of the part. Best post solder process that affects solder the most is handling.

the footprint is IPC standard which I have found to be less forgiving than the Jedec one for tombstoning. Enig finish - 5 thou stencil. We have historically used homeplate design but I am leaning towards 1:1. Leadfree application. aj...
