The secondary (primary to some) concerns are what you put into the waste stream and how you treat it, and what the chemistry of your residues does to the seals on your machine.

Look for the following machines: Aqueous Technologies ECD EMC Austin American The above mfrs. make "industrial" grade dishwashers for assembled PCB de-fluxing. Search any of those names followed by "..... batch cleaner", and your search engine will

Best to use Tin treated with TinP Additive. This ensures the Tin is fluid enough to Dissolve any Leaded residues. Run the machine for one hour at 275C then take out wave former and as much of the workings of the pot as possible. Then start bailing ou

Brian, We've see foaming issues with our wave flux occasionally when running large slugs of product through the wash. We love the wave flux and changing it was not an option. Our process parameters for the wash machine we're derived via a validati

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

Is this happening in the mornings? Are the operators allowing the machine to come up to set temperature before they run it?

Approaches to getting started are: * Most batch cleaning equipment suppliers provide both open and closed loop options on their machines. Talk to them about upgrading your machine. * There are companies that specialize in supplying closed loop system

It has been happening in the mornings, and we do have a weak middle element, but our temp is always above 60C. we have it set at 65C. the service manager for the machine assured us that temperature wasn't the issue. Also, our flux application for ERS

Surely somewhere the cleaning or rinsing liquid gets to the other chamber. It is possible that the chemical migrates to the flush or flushes the chemical into the chamber. I have had a similar situation, high foam, injection vertical spray offline st

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
