[PVRCNC] Desoldering printed circuit boards

[Jim K4QPL]

I have liberated as office surplus a bunch of telephone system pc boards 
that along with a lot of useless components have about a half dozen DPDT 12V 
mini relays and diodes on each that would be valuable additions to the junk 
box for band decoders, isolation and miscellaneous switching of stuff around 
the shack.

Trying to use a conventional iron, desoldering braid, etc. to desolder and 
heat six pins simultaneously to remove the relays is not fun and the time 
required is not cost effective. Any ideas?

Thanks es 73,

Jim, K4QPL
