The automatic stencil wiper - first line of defense * The Printing process and why we need to focus on the wiping function * Frequency of wiping * Wiping options ...
Solder paste screen printing is known to be one of the most difficult processes to quality assure in Printed Board Assembly (PBA) manufacturing. An important process step in solder paste screen printing is the under stencil cleaning process and one of the key materials ...
The stencil cleaner can be one of the most versatile tools on the manufacturing floor. It can be used to clean electronic modules in various stages of the manufacturing process. In fact, an automated stencil cleaner can clean just about anything you come up against in your PCB assembly process.
The effectiveness of cleaning stencils and misprinted/dirty printed circuit boards can be effectively monitored. This can be done by washing known clean circuit boards and then checking to see if they have stayed clean as a result of the washing process.

Soldermask Screen Printing -- a few decades ago when I was a kid, I printed soldermask and legend inks on circuit boards. Printing solder mask, (PC-401, SR1000, LPI) I would use SM-1000 stencil material on 86 or 110 mesh. I've been trying to find sm-1000 but with no luck. does anybody know what the current stencil or is this old technology that is no longer used? Thanks
