Does the machine act slow when cold? Might need to be cleaned out. One year old? No warrenty?

If you are running 1 shift 8 hours a day, I would PM the valve at least twice a week depending on dispense medium. With the opoxy I used, I cleaned the valve and needle every day.

We manufacture both bulk and localized ionic contamination testers. My answer is from the perspective of the cleanliness testing method. The issue with all bulk ionic contamination testers (Ionagraph, Omegameter, Zero-Ion), is that they test the en

Thanks for the reply. Just one more question. If there is less solvent but the residues are harder to clean. would there be more contaminant left on the boards? Has anyone did a cleanliness test?

ZOINKS!! Yet another thread on PCB support. These discussions get *almost* as heated as - dare I even mention - stencil cleaning. Let the fireworks begin!

Contaniminates are always a issue. What chemicals do you use? Do you plasma clean? Are the production personnel wereing finger cots to reduce added contaminates?

Pb(N03)2 + H20. In any case I can understand that $38billion spent has done nothing to clean up the Pb legacy. Although the world chose Pb-free as an approach for now, it may change in time. Regards, Gary

It's possible that the flux residues from the solder paste used in your SMT process is not compatible with your water wash process. For instance, some no-clean fluxes leave resudues that are not water washable. When these residues are washed, they de
