Greeting-
I work for a company that makes ids that are printed on plastic cards the size of credit cards/ drivers licenses. The card stock is coated with silica and some are not. I was tasked recently to resolve the jamming issues we have been experiencing with non-silica card. I've come to the conclusion non-silica cards have a higher level of stiction when compared to silica cards. My question is, what are some of the methods to remove stiction? So far from what I've read:
* use canned air and blow it in between the cards
* increase the surface roughness spec
* store cards in a mylar bag sealed with nitrogen
One interesting thing is non silica cards with magnetic strip do not jam, I contribute this to the mag strip am I correct on this?
regards
frank
