| Beware of old AntiStatic foam |

Another way of reducing power level in an ultrasonic cleaner is by using beakers suspended inside the tank. There are custom lids to hold them suspended like this. You then hang your delicate parts in the beaker, and the beaker attenuates the vibrations by absorbing some of the energy. |

Good Morning Intabits, I too have ICs stored in antistatic foam that is crumbling, but no corrosion. How about putting your ICs into some high quality ZIF sockets instead of soldering them? :-// |

It's not just anti-static foam that deteriorates, but all foam. I recently dug several of my old HP calculators out of the closet (HP-25, HP-41) and the foam lining in both of the cases had deteriorated and left a black mess on the keyboards of both calculators. |

Back in 2004 I bought a sheet of conductive foam from Jameco. The sheet was about 2'x3' and it wasn't cheap. About $30 I think. The plasticky part is shiny and the sheet was very stiff. It didn't bend when held horizontally by one edge. Now, 17 years later it's still fine. I suspect it's made from polyethylene or polypropylene - not some kind of urethane. |
