When I look at the picture labeled chip-cap.gif, i see 2 horrible
looking solder joints. There is insufficient solder. The solder is
crystallized. There is insufficient solder in the meniscus.and it
shows evidence of insufficient heating I do not see any perceptible
bulging out of the cap at either end.


You obviously are unaware of the new solder joint acceptability spec
for RoHS assemblies.

Grainyness is the norm. Also, "modern" motherboard houses have been
using stencils that are too thin for years, so they have all been low on
solder for a long time.

There is no such thing as a clean, bright, shiny solder joint any more.
The days of 63 / 37 perfection are gone.
