Interesting discussion on using rubber erasers to "polish" fiducials.....

I presently have a customer who has to polish his fiducials in a similar manner before his vision system  can locate our boards.  I want to try and help this customer get out of this practice.  The board has a HASL finish.

Can anyone shed any light as to the root cause of this issue and reccomend solutions (preferrably board related fixes - if there are any).

 I have also read in the forum that gray scale vision systems can remedy this.
