If you are really nervous about sending that chip you can get U or square profile steel slightly larger than the chip width and height and cut a piece 1 1/2" long of it. Wrap the chip in aluminium foil and insert in hollow then mail in a small padded envelope. I suppose this is truckprof. Hehe. It has never occured to me that there may be delivery services that run a truck over a package and then refuse to acknowledge this (except in this country of course, where they drop the packages in the box behind a scooter's saddle and drive onto/off the curb(s) 10-20 times with it inside at the very least). Sometimes our packages contain shock sensitive electro-optics and cameras. Aargh. Peter -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
