We have four pick and place machines all exibiting a residue that seems to build up over time on wiring and electrical components. This residue appears as a white haze on wiring, caps and fuses (these are the components where it is most obvious). You can easily wipe the haze off with your finger almost like when you breathe on your glasses and clean them. It is very strange because it is isolated to these machines only. Additionally, it seems to be isolated to certain power circuits - example, a row of clear glass fuses, one for a 48VDC circuit, the other for a 24VDC circuit and the 48VDC circuit fuse will develope haze as the other will not. Has anyone seen this before and now what might cause it?

I do not have a answer for you, but it sounds like electro-static charge is making air-borne particles stick to the machine. What are the air handling conditions? Could be you need a better filtration system. I use a HEPA filter system. I've always wondered if it is necessary, but then again I've never had problems either. Which reminds me, I just noticed the "change me" light today.
