[sdiy] Trays for through hole resistors?

[Altitude]

Just for everyone's reference, this is what the Plano 3500 trays look like.
9 bins the perfect width and depth that can hold a 200 pack comfortably
(there is one half depth tray in the center front position).  These also
come in a tackle box 4 drawer enclosure with an additional bin on top (very
handy).  I paid $14 for 4 of them on amazon.

Brian,

Perhaps oxidation was not the best word to use, though oxidation is part of
the problem. Also notice that I said *HELPS* prevent corrosion. I live in a
subtropical environment. I'll now describe the situation at my home
workshop, as it's not so bad where I work because it is air conditioned...

If I store parts in a non sealed container (eg: a parts cabinet with
drawers), after a few years the component leads lose their shine and even
become black. They are almost impossible to solder to. If I store parts in
snap lock bags this does not happen. I squeeze as much air out of the bag as
possible before sealing it. For any critical (expensive) parts I put a
silica gel satchel in with them.

Sometimes it's more important to observe what happens in the real world, and
react to that, rather than get hung up on semantics and science.

Regards,
Stewart.
