Is there any harm in washing SMT soldered with NoClean paste? The PCA has some large thru-hole connectors that we would prefer to do as water soluble on out selective solder but the SMT consists of LGA's and other low parts that we would not be able

We will be hand soldering a small number of PCBs per week (both through hole and SMT) using a water soluble flux. We will be using both standard leaded and lead free solder. The completed assemblies be hand washed in a sink using hot water. Do we

In addition to your local water departmet I would suggest that you also contact the EPA.

Davef is right on as usual. We are doing exactly what you do. Some smt with no clean paste then the plate through connectors on our selective solder machine using water soluble flux. We then clean with a ultrasonic water process. We do see the re

Hi Bill, You should contact your local water work dept. and work with them. Every county is different. Sometimes it not what you put in the drain, but how much. They may want to monitor your drain, which is standard stuff. Be prepared to show th

I realize I am jumping in late but here is some REAL information. Waste water is controlled by EACH POTW (waste facility). It is NOT centralized as in EPA. The POTW's are primarily concerned with what might damage their pipes. First among their conce
