MIL-C-38999 covers the round connectors that stick out
of the front of our boxes and let them communicate with
the airplane. The outer metal shells are olive drab iridite
over cad plate, and they mate together with a twist/lock
collar.
When the suspect solder joint was touched with an iron and some
Soder Wick, the whole thing disappeared. There appeared to
be good wetting to the lead and the pad, but very little
flow up into the barrel. Sorry, I don't have a picture.

I am not familiar with the P/N 38999 connector yet you speak of a spacer
which stirs the mind. Can you share a photo of the animal you are
talking about and the spacer application with vertical fill anomaly.

One of our boards has a number of 38999 connectors, with connections on
the top side hidden by a spacer. We've had one SJ failure because
of inadequate solder fill up through the PTH. We'd like to determine
whether this is an isolated problem, or whether the spacer might be
impeding solder flow. Of course, we don't have any boards to sacrifice,
and we can't see anything with direct transmission x-ray because the
connector is in the way.
Anyone know of a lab somewhere nearby that offers scan beam
laminography service?
