Hi everybody,
        We recently start to use an ultrasonic stencil cleaners for our stencils.
It' work well, but after some time, we saw a lot of fiducial that the black
epoxy have been partially or totaly remove.  I want to know if someone had a
similar problem with a stencil cleaner. Also, we looking for a material to
repair the black epoxy of the fiducial ( for now we use ink pen, but we need
to redo the job everytime we change of product). Our stencil are from UTZ
and our stencil cleaner is from SMART-SONIC.  Thank you.
