Which bit do you use? A grinder or a saw bit



I've used a Dremel tool to remove relays, as well as other components, by
cutting them to pieces, carefully, of course. Then I unsolder one pin at a
time. Unless you need to do failure analysis on the bad part.

Cutting off the relay is the hard bit, as many have quite hefty bits
of steel in them. A cutting wheel in a die grinder (aka dremel) works,
but can be slow.


My own method would be a good hot iron, plenty of solder braid and a lot
of patience.

I've often found that in a pinch, you can wick the solder out, re-fill
the holes with new solder, re wick the holes. Sometimes the
re-filling process can reflow the whole joint instead of wicking out
the top half and the bottom never gets hot enough. Of course, not
perfect, and should be done on a scrap board.
