Believe it or not, we use kid's markers like Crayola. Some colors come off more readily than others so you may have to experiment. We use it on aluminum so it may not be just right for you but it's an inexpensive test. Kind of made us happy when m

Around here that opens you up to some financial liability if ANY lead is found in the sewage, if they can't pinpoint the source. Every user over X lbs./month (dunno the specifics, just got this from our hazmat guy) is on the bubble for anyone else's

Dave, I'd be skeptical too, with that response! I've got a Culligan DI system installed here, and it's got it's own resistivity test meter. When the light goes red, it's time to call and get my resin changed. It's worked out pretty well here. Ba

I have requested info on the disposable cartridge. I was told it was made for lab use and has an indicator to show depleated use. I will try to determine how the indicator works, ie. measures quality at the outlet (hopefully) or some other scheme?

OK, I've found out more on the disposable cartridge. It is made by Siemens. There are four in the series. One of the part numbers is 3C0600002. It has colored resin and changes color to indicate depletion. Has hose connects each end. I will try

I am looking for IPC or other published standards that specify cleanliness levels for: 1) solder paste stencils 2) selective solder pallets When we cleaned PCB's we used a limit of 4 M-ohms. Now that we have transitioned to No-Clean, I am wonderi

There is no standard, nor should there be. You need to establish a standard that meets your customer requirements. The problem with those old-timey standard is that there's just so many choices. What works for you just might be too strict [or loose]

In the following thread, http://www.smtnet.com/electronicsforum/view_message.cfm?message=9584& John Thorup touched on some applications where no-clean fluxes could be a bad idea. I'm looking for some more detailed info. (papers, references, texts

Your lack of obvious solder balls indicates you have a decent process. However, there are still small solder balls that are free and floating on the surface of the boards prior to wash. That same solder ball is washed off and ends up in the wash solu
