Why is everybody so hung up on not doing something in a slightly different way? If you'll look at who I work for, you may be able to figure out that I don't always do repairs in the shop, sometimes my shop is 2000 miles away, and trying to get a room for a humidifier can be a major hassle, so I fog up a dressing room. If you only stay in the room long enough to put in the chip, you don't get condensation enough to corrode contacts. When you step out of the room, the moisture evaporates quicly enough to not be a problem. BTW, conductive foam is not always available, and it eats the pins. Often, the cute ladies in the catering room are more than happy to give me a sheet of foil. Someone asked for an easy and cheap way to plug CMOS chips without the possibility of damage, and I responded. I didn't say it was the only way. Lighten up, eh? Galen Watts, KF0YJ
