Does anyone know of a less expensive technique to monitor board cleanliness (chlorides in micrograms/in2) other than omega mater - ion chromatography is costing us an arm and a leg.

We are a high-mix/low-volume operation and end up cleaning 40 - 50 stencils per day. Does anybody know of an automated inspection system or "scanner" that can check a stencil for cleanliness?

Kerryn, It's the first time I hear someone who needs an automated inspection machine to check the cleanliness of stencils. Why not improve on the cleaning method itself. I use ultrasonic batch cleaner. It takes 3 minutes to clean a stencil, 2 minutes

Consider running two sets of stencils and washing every four hours.

sure sounds like a lot of busy work just to make solder joints for a vacuum cleaner.

Dave, We have very short runs (less than one hour). We have stencils all over the place waiting to be cleaned. It is too time consuming to scope each stencil to inspect for cleanliness. Do you know of any automated or scanning devices that can ra

Thanks Phil. However, my objective is to identify stencils that are not 100% clean prior to sending to inventory. I want to catch it before the solder paste has a chance to dry and harden in the apertures. Kerry

NASA requirements may be a good starting point http://www.hq.nasa.gov/office/codeq/solder.htm
