I noticed this especially on your resistors and even some surface mount
transistors.  Surface mount pads in particular need to be kept clear.  It
wasn't the label text, but rather the symbol.  In the case of the
resistors, it was the wire symbol extending from the body to halfway into
the pad.  The transistors seemed to have a silkscreen picture of a pad on
top of part of the pad.
