Stencil Cleaning [AIM LeadFree] * Stencils should be cleaned frequently enough to ensure total removal of any bottom side residues, but not so infrequently as to allow the same residues to dry or cake on, making their removal much more difficult. * S

I don't have an opinion on nano coatings since I haven't tried them. Our suppliers keep pushing it so I'll eventually check it out. The reason I zeroed in on the FG foil is because I almost fell into that trap. Several years ago I wasn't aware the

there are many reasons why FG and Nano are used and many papers written on them. Nano ssems to be the topic of interest right now. I agree it is mostly for printing fine and untra fine pitch. With that comes under stencil wiping to keep the stencil o

You may also look into a product called Nano Protek. This is an application that helps reduce your cycles and increase productivity. In some cases beter paste deposition has been recorded. Contact your stencil vendor or I can give you information.

I'm not sure why anyone would pay extra for FG (fine grain) stencils. I've run studies comparing traditional YAG laser, fiber laser, and E-form stencils with regular stainless, FG, and nickel foils. YAG is the worse and should only be used for pret

I am not aware of the Nano protek flaking off. However I do believe it can wear off through abrasion. Unforunately there is no red light goes off when it has worn unless you have good paste inspection. Even when it wears it will not take you to a neg

Use nano-coating and your stencil will last a-hunnit-fiddy-million cycles. Yessur.... In reality I cant say that I have ever seen a worn out stencil. Damaged and dinged, but never worn out.

On understencil cleaning: * It's a good idea to do this to reduce printing defects, as you say. * We clean dry. * Our cleaning frequency varies acording to product, maybe ranging from 10 to 20 prints, averaging around 12 to 15. * As long as cleaning

Hi Dale, I have copies of the articles of which Mike references. If you need copies for support, contact me at: bill@smartsonic.com. Rinsing should be done by ultrasonics also. Spray in atmosphere systems will not penetrate into the same tight ar
