Many suppliers offer a circuit board removal tool which is usually a small
plastic tube with a hole in the middle. This tube fits over the nylon board
fasteners and allows you to easily remove the board.
I have found that when my girl friend buys a pair of new shoes there is a
similar tube in each shoe that helps keep them in shape. These are great
for removing boards because they are longer than the tool and fit perfectly
over the board fastener. Even better, they are free!
