[Elecraft] KSB2 Module - board pad

Fri Aug 9 10:19:03 2002

Tom,

One thing to verify.  Many times when doing rework, I have thought I did 
the same thing, only to find out that the solder around the component lead 
came off, and the pad was intact but covered in flux to make it look like I 
ripped the pad off. Hopefully this is the case for you.  You can check by 
gently scraping with a dental tool, and looking under a magnifying glass at 
the area.  If the pads did come off, the board underneath will be green 
fiberglass.

If the pads did come off, Tom Hammond's instructions are the way to go, 
unless some of our fellow listees come up with something better.

The only thing I would add to Tom's instructions is that you need to be 
cautious of the small sleve that is formed when the hole is plated 
through.  This may still be in the hole, or may have come loose with the 
pad.  You will want to be cautious and watch that it does not work loose 
while you are reworking the connections, and short out across stuff.

Good luck!
