Are there incoming rinse water quality standards - specifically maximum concentrations of magnesium and chloride - for an aqueous or semi-aqueous cleaning process? If there aren't standards, does anyone have experience with what the max can be befor

This has been a problem from the start. I used a digital flowmeter to check exhaust and both sides are pretty even, however, I do not know if its exhausting too much or not enough, just going on the PE specs...but then again...do they really know. I

Setting up Water Wash Plant

Electronics Forum | Thu Dec 11 12:17:16 EST 2008 | bmaheu

Setting up a PCB washing "system" and the facilities required for a cost effective and repeatable cleaning process depend heavily on the application (water soluble versus chemistry cleaning), (batch cleaner versus ln-line) and local factors (quality

Contamination of components

Dave, We use water soluble flux. We currently do not do a solderability test on incoming components, I'm thinking that this is going to be a "must do" with these components. Larry

We use a dish washer system with good success. The only issue is foaming, sometimes this can be a problem. We have be experimenting with antifoaming chemicals. Some success. I would suggest a dish washer system that has ionic system in the wash pump

It would help to run a carbon, anion, cation, mixed-bed configuration with pure DI as the final rinse. IF your incomming water is really bad you can run a RO unit to "prepare" the water for ion exchange. Do you run omega meter or ionograph testing
