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.
