A clever way of testing solder joints

[drezdn]

I haven't tried this yet, but it looks like it might be worth trying. How to test solder joints.

Not to brag... but I'm *very* careful and particular when it comes to making solder joints.

I go slow and careful.
Cannot think of a single instance when I had a bad solder joint of my own doing.
(maybe when I was much younger and first starting this thing called electronics)
If I make one and it doesn't look or feel right, I re-do it right away.

Been repairing/modifying/fixing/building electronics stuff for many years now.

This, definitely. Not sure the tin foil thing will test anything but a joint with too much solder. A good one has a nice, slightly concave fillet and the lead is clipped slightly above. Which makes this test a little misguided imho.
