I would like to know if there is any information regarding how often to clean the stencil by the printer cleaning system. I am running a board with an ultra fine pithc QFP. Is there any guide available? Regards, Mario A. Berrocal

Thanks to all for clarification - I now appreciate the different methodology between "in-line" & "end of run" but am still unclear as to advantages / disadvantages of paper versus non-woven material ie stencil rolls for in-line cleaning. Any info wo

Ahne [?] You say, "There are almost as many ways to be successful with this as there are ways to do it wrong." What do you believe are the successful and wrong was to go about cleaning stencils after the run is finished (or temporarily interrupted)

How are your experiences with stencilling 0201 components on large circuit boards, i.e. 400 * 250 mm ? Will there not be too much mismatch between between stencil and (FR4) boards? If so, would dispensing be a solution? Any other solutions?

Here is an excellent technical explanation of stencil cleaners and their differences (spray, ultrasonic, chemistry type) that I found in the archives: http://www.smtnet.com//forums/index.cfm?fuseaction=view_thread&CFApp=1&Thread_ID=3026Message1232

I enjoyed that little exchange between the presidents! It sounds like the guy from the ultrasonic company is more interested in selling his chemistry versus selling a stencil cleaner. The other guy had a little of the sneaky salesman talk but seeme

Acually, Dr. Shocker, DaveF is correct. The high power spray can bend the metal between the aperatures on fine pitch parts. I'm sure it's not common, but I have seen this happen. I have not, however, stood on any stencils. Sounds like fun.
