Hi Bill, I agree with not cleaning the no-clean. If you're looking for a cleaner because one of your customers is requiring no residue be left on the PCB's, I'd investigate switching to a Water Soluable Process for those specific assemblies. (You'll

Larry, the best paste thinner is the one that your paste supplier recommends. You should check with him. We have no problems removing the no-clean paste with alcohol. If you want to give it a try, make sure you use IP alcohol, not alcohol based flux

We have an assembly that requires a number of high density connectors to be placed after SMD. The process will not allow a normal wave solder setup due to the population of SMD comps. We cannot use a selective solder pallet due to profiles. We are

Hi Steve, I work for an analytical laboratory that specializes in ionic cleanliness, and we have found through the variety of cleanliness issues we encounter that the Envirosense cleaning chemistries are very effective also, so you might want to add

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

Hi Rick, Cleaning No Cleans is becoming more of a norm. It is true that changing to a OA flux/paste would be a easier process to control from a cleaning standpoint. A water soluble process will cost a great deal less as well. However, if your pro

We are purchasing an ultrasonic cleaner to clean pcb asseblies that have been produced with water soluble flux based solder. After cleaning a batch of assemblies, the water in the cleaner will need to be disposed of. My question is: Do we need to

Hi Dave, To close-loop or not to close-loop, that is the question� I can not speak for all machines, but in our case, close-loop systems are actually less costly to operate than open-loop systems (we make both). First, determine the volume of wate
