Testing out a batch of 555 timers I just received. They came in a plain plastic bag so I was a bit dubious about that. So far they all seem OK to me though. The merchant even threw in an extra 4 for good luck I guess? Either that or they just couldn't be bothered counting.
Their little legs are delicate though. So the foam protects them from damage. All microelectronics are static sensitive to a degree too. Although 555 ICs are pretty rugged. Still, it'll never hurt any IC to store it in conductive foam. So it is worth it to me from an organizational point of view to just store my ICs in foam often. When I was done testing this batch I cut a piece to fit into a drawer, and put all of the chips on it, and into the drawer too.
