Best practice for stencil cleanning | 14 May, 2010

Hi

Since we are a small company with a small smt line, we did not have problems with our stencils because they are small and could clean them with Alcohol and wipes, but now we are growing, and now I am having a 20X20 stencils frames to deal with, so I have to use something more advance than just wipes and alcohol, any ideas or practice I need to know? thanks

We used to use spray machines. We now have a PMR ultrasonic cleaner. Ultrasonic is the best in my opinion.

We used to clean our stencils by hand as well but 2005 we steped up to a ppc-n29tp stencil ultrasonic cleaner has worked great for us I would suggest a machine cleaning system it gets the stencils more clean then doing it by hand

I've worked at several companies that have used Smart Sonic ultrasonic cleaners. About a year ago, we purchased the Smart Sonic 1550 and Enviroguard. The Enviroguard produces DI water for rinsing and also handles the solder waste. Also, Smart Sonic has a non-alcohol based wash detergent that works great and doesn't smell bad. I've done microscopic analysis of stencils and PCB's washed and dried by hand and compared it to ultrasonic wash. There is really no comparison; Ultrasonics clean it far better than doing it by hand.
