[Elecraft] KSB2 Module - board pad

[Tom Buchanan]

Tim, Ed, and Tom

This was my first post to the list and I appreciate the quick response and
helpful information.  I have just returned from the workbench and I am happy
to say that it was flux on top of the pads.  Although the pads appeared to
be gone they were there under a very thin layer of flux.  All day I thought
about why did I mess up the pads?  It was a relief to see them still there.
