Today's experiment: cleaning boards with a grinder.

I use an air chisel. Things go flying... no dust. I was thinking about using an oscillating tool, but I don't have one yet. Someone mentioned a scraper blade on a sawzall. probably the same concept as an air chisel.

I don't like the idea of the fumes from heat gun / torch / burning and I don't like the idea of lead dust from grinding. I'm beginning to wonder if this is even worth the trouble to take these components off. But, I say that now when I have a couple hundred machines to process and around 20 servers... that thought may change if I run out.

Hoss, I get low grade boards out of microwaves and refrigerators.

I thought acid was used to dissolve the metals.

I used a small metal chisel tonite on some bigger IC chips, started on one end and lightly tapped until the chisel started under the IC pulling the legs out of the board. Keep tapping on the chisel and you'll "walk" the IC right up off the board with the legs intact. This chisel is only 3/8" wide and sharp so it'll slide right under the chip. Gonna start pulling the bigger chips off of the TV boards only. Sorry for the HIJACK.
