the board in question is from Foba Laser Engraver, it's a surface contamination coming from.. everywhere, a lot of moving parts that are lubricated. I'm now studding chemicals that we may use for our kind of rework & cleaning. We may think of modifyi

We've configured SMT and Wave lines such that each line can run either No-Clean and Water soluble process. As we are doing cleanliness study, an observation is there may be cross contamination when we share the Rework benches or PCB trays between No-

HI guys, I am new to this forum, Earlier author is asking regarding of Lead free rework. 63-37 is non lead free and this will contaminate the product itself. I do not know what are the components that you are facing to rework with. But try to set th

The is a serious concern of lead contamination of leadfree solder connections. For background, search the fine SMTnet Archives. For instance: http://www.smtnet.com/forums/Index.cfm?CFApp=1&Message_ID=30307

Siaomuay, What is your flux and peak reflow/rework temperature? Do you use chemistry in your cleaner? Regards, Shean Dalton

I would recommend not to mix leaded irons to do non-leaded rework. Especially, if you are working on ROHS compliance project that will create contamination. Weller and Hakko still have tips for leaded soldering tips, you can chechk on their web sites

do you see signs of contamination or oxidation? if not why not just send them to the board house and have another OSP coating layer applied?

The latent contamination in sponges seems to be a minimal concern to me. Sponges will harbor more bacteria than a wet rag that is washable, but that is of greater concern in the kitchen than the rework line. Keeping a properly tinned solder tip is m

Also, have you considered the possibility that if you solder on an existing joint on a board that was built with SnPb solder, even though you are using leadfree solder wire, you would now contaminate the tip of your soldering iron. If you then start

Do not believe every thing your suppliers tell you, even a written cert does not guaranty compliance. We recently purchased a Niton XRF analyzer. The first day in use we found component�s that were made for us "RoHS" that were far from compliant. Peo
