[Blindtlk] Soldering revisited

Thu Aug 11 23:27:11 UTC 2011

That’s what I was called growing up, but I can tell you that I’m 
certain it doesn’t much matter in this case.  I can’t see how I could 
possibly do it under a CCTV, and anything short of that isn’t going 
to give me enough magnification to do it visually.

If this is going to work for me at all, I’d be able to do it under 
sleepshade with a continuity tester to test connections.  It’d be 
slow work to test that way, but I’m probably going to have to do that 
kind of testing anyway.  Testing needs one mini-grabber clip on the 
component lead and a needle probe to make sure you’ve got a solid 
connection at the other end of the trace you’re soldering it to.
