Since no one has brought this up yet, I guess I will. I have seen some
boards which were too *wide*, as opposed to being too thick. Imagine
putting a square stick into a square hole. There are 4 dimensions
of interest.  Consider the 4 edges of the section of the card which
is inserted into the connector. Two of those edges have the gold fingers.
The other two edges most people don't think about. Take a good look at them.
Do they show signs of rubbing or damage? If so, then the board is too wide.
It may help to take a file to those edges. This isn't always the problem
but is worth considering.

Also many manufacturers use short ejectors. I used to use longer ones
which made a big difference in getting cards out.
