We currently half cut our fiducials with our Laser's and gain a black enough
contrast that there is no need for these to be filled with black adhesive
after cutting. They stay black through all cleaning process's.

Is there any other methods of putting fiducials on the stencil? Our vender
Laser cuts the fiducials half the thickness of the stencil then fills it
with black adhesive. After a while the black adhesive starts to deteriorate
and my phone rings of the hook. I usually get good results filling the
fiducials on the thicker stencils with Loctite 410 black adhesive. But not
much luck when dealing with 5 or 6 mils thick stencils. Any comments
appreciated.
