[Elecraft] OT Slightly: PC Board Recovery -Plated Through Holes

[Dale Putnam]

Hi Lee,
  Man I hate when that happens... solder wick works well, but can you find that when you need it?
A drill might, but that has so really poor happenings, and opens the door real wide for our good friend(?) Murphy, with the least problem to be a loosened hole through, the worst being a messed up board. How about air? heated the hole, blowing a can of compressed air through? Another thought would be, stripping the braid out of the smallest coax you have handy, two or three inches to start with, wiping flux on the stripped out shield, and use that for solder wick...? Or.. simply heating the hole, then sliding in a stranded wire, through the hole... a "fur piece" then either cutting the wire off, and pulling it out... or continue to heat the hole and draw the wire through until it is clean. Obviously this requires a proper sized wire.. but then you have a few other holes to size the wire with.
Good Luck, and remember... it isn't the speed that accomplishes the task.... it is the lack of returning to fix it again that makes it a good repair. --... ...-- Dale - WC7S in Wy

I was putting together a kit this evening (non Elecraft) and discovered I was using the wrong instruction sheet version to the parts and board I was using.  (Always check your parts before beginning - which I did not)  I had to putt about 10 resistors of the board.  They are plated through holes.  I did not have a vacuum desoldering station...so I have to think of somethingto get the solder out of the holes.  A small drill?  Anyone has some comments?Lee Buller - K0WA"Embarrased to say the least"In our day and age it seems that Common Sense is in short supply.
