Hi ya'll!!

Got another picture for ya to look at for me. We've got some PCB's in
receiving inspection that has these little nodules in plating inside all of
the barrels. Go to:

and look at Barrelplate.jpg to see what I mean. These are microwave PCB's and
have almost all of the surface area on both sides covered with with solid
metal planes, and no solder mask.

Is this a normal appearance? The plating inside the barrels look to be a much
lighter color than the plating on the surface planes on the PCB...you can see
that in the picture as well. I don't know what I'm looking at, maybe someone
could help me. I'm being asked if this is okay...I don't know if it is or
not. I'll try and take a better picture if I can...

Thanks!!
