The best suggestion one can offer is to view the archive section of this site. It is full of discussions, suggestions, advertising, claims, counter-claims, etc. Just search under the words �stencil cleaning�.

This forum is becoming a salesmans dream! I agree with the first guy, check the archives as there is alot of information about cleaning and media. Our company uses a Kerry SC1000 machine very good process but mechanically we have had problems with the unit, 10 out of 10 for cleaning misprints, adhesive and stencils.

The cleaning media is Dr O. K Whack's Vigon SC200, distributed by Hereaus.

Is there a cheap and effective method for stencil cleaning? Getting a equipment is out of the question.

�Cheap� is relevant. Is $ 3,500 for equipment cheap or expensive? If $ 3,500 is cheap, than we have a solution for you. If $ 3,500 is expensive, then purchase pre-saturated chemical wipes, latex gloves and a hazardous waste bin. As for �effective�, equipment is generally effective. Manually cleaning stencils, although cheap, may not be as effective. Ineffectively cleaning stencils is certainly not �cheap�.

Stop!!! Whoa!!! Time-aut

You have equipment like "Siemens 80S & 80F, Sanyo TCM 3000 and GSM" and you're not going to convince people to clean the ever lovin' bejuice out of your stencils? You're thinking handy-wipes are going to get it done? What am I missing?

Hi Dave,

God no! I am not suggesting that anyone should clean stencils by hand. My answer was facetious. The questioner asked is there was a �cheap and effective� way of cleaning stencils without purchasing equipment. Cleaning stencils by hand may seem cheap but it is ineffective. Ineffective cleaning of stencils in the long run is not cheap. In fact, it is very costly! Add to this the fact that there will be people wiping off lead onto a rag and you now have safety and disposal issues, futher also adding to the cost. The point is, being cheap is very expensive!

Mike, I know that. I wanted to be talking to Bayanbaru.

Plus, I know you have no placement machines. You use ultrasonic plastic welders and screwdrivers.

Sorry fellas -disagree. We only clean our stencils in the ultrasonic machine at the end of the run. If the same pcb is up the next day we clean them by hand. We use Electrolube SSS and the used rolls from the in line under stencil cleaner. Wipe the top thoroughly, discard paper, wipe the underside thouroughly, discard paper, Hold the paper under the apertures while you blow through compressed air from the top - BE CAREFUL - no damage now! You may have to use several bits of paper for this part if the stencil has mucho holes. Wipe over top side again. Of course you apply a bit of your cleaning fluid to the paper/rag whatever, before each step. Wear eye and clothing protection and perhaps the rubber gloves if you like. Don't use paper/rags (Irish Linen is nice), that leave bits behind.... Check it out with the little measuring microscope when you're finished - CLEAN AS! SSS works well on both paste and adhesive - it's expensive stuff but like Peck's Paste - "a little bit goes a lo....ng way".
