Dear Technetter

To gain best bonding of dry film to the base material some of the 
parameters must be controlled strictly such as temperature of rollers of 
laminator or sodium carbonate and may be the most critical parameter is 
surface roughness. Our dry film supplier suggest  roughness value for Rz 
1,5 - 3 microns for Ra 0,15 -0 ,3 microns. I want to have your comments 
if  Rz is normal I mean between 1,5 and  3 microns let us say Rz is 2.10 
and Ra is 0.41 microns, how can we interprete or comment on these value; 
does it bring good bonding with it or it is an obstacke for dry film to 
bond to surface
Thanks in advance for your interpretations and knowledge  share
Best Regards
