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.
