It'll be a DI system. As it turns out, we contacted another EMS company down here, and asked them what they did. They pointed us to their supplier. Conveniently, the same company will set up the DI system for us, and the post wash filtering/plum

We've just acquired a batch washer at an auction, and want to install it as a closed loop system. The only problem is I have no idea where to turn or what to look for for a drain filtering system that will allow us to make it a closed loop system.

We seem to have an overwhelming amount of foam produced in the initial rinse portion of our wash (enough to cause it to overflow). We are using an Austin American Hydrojet Mach III Inline Cleaner. To my understanding the first rinse of the boards is

Brian, We had similar problem in our inline wash machine time ago. We checked everythin on equipment (filters, DI water purity, sprayers angle, etc). To make the long story short, we found out that the problem was caused by a new solder paste. This s

Filter & match a PH level their happy with & release? I would push them to put something in email or letter for what they require though, otherwise it could come back & cost you

I've been looking for information on how, if at all, any of you treat water after a pcb batch wash. In particular, we have a Trident LD machine, using Zestron cleaning chemical. We have a carbon tank and two mixed bed media tanks as well as two 5 mic

You have a lot to think about! What does the flux manufacturer recommend as far as specifics like water temp or pressure? Do they recommend high temp di-water a detergent or saponifier? Do you currently have a cleaning machine, batch cleaner or inl

I have nothing to add technically but we have been washing no-clean for years. Use very clean filtered DI water to avoid the white residue issue and some good detergent or sopanifier and you will get great results.

Our facility helps customers clean no-clean soldered boards on a regular basis, and it definitely can be done but is a little more challenging than boards built with water soluble flux - one piece of advice I would give is to use low water pressure (

WA Engineer, If you are able to change over to OA instead of RMA, you can clean effectively with DI water. (I know that some Military contracts specify RMA) Most systems are designed to filter the waste water of ionized contaminants before dumping t
