Just wondering if there is anyone out there using a national (US) company to provide ESD smocks, cleaning and repair. Spending a ton of money handing them out to people just to have to replace them in a short period of time. Any recommendations??

Something else I forgot to bring up....can we get by using our normal water soluble process or are we going to be able to clean under these things? The BGAs have .18mm and .30mm ball heights.

What is commonly done in the industry regarding when to clean the stencil, squeegees and replenish the solder paste? Is it every 4 hours, 8 hours or something else?

As a minimum, we clean the printer setup every shift change. Probably the best advice on this is from your paste supplier.

Its most likely flux residue from your paste. This is normal in my experience. Just clean it out. Some paste fluxes are waaaay worse than others.

Bi monthly?!!? What are your exhausts getting clogged with? You have that much dust in the air that cleaning every two weeks is necessary?

If the hand soldering is done right and you use little to no extra flux (other than whats in the solder wire) you should be ok. You should still verify with some testing however... You need to make sure any flux used is activated, thus rendered benig

I should have mentioned... the only flux we use for the hand soldering is wire-core, no bottle flux. I think it should be a non-issue to leave the activated wire core flux residue. I'm just looking for some way to prove it to the designer.

With such a low standoff [eg, 1-2 thou of solder], we doubt that you can clean under QFN, either. For more, search the fine SMTnet Archives to find threads like http://www.smtnet.com/forums/Index.cfm?CFApp=1&Message_ID=19247
