Hi experts, I asked our chinese board manufacturer about their recommended procedure to clean miss-printing. The answer was that they use Absolut Alcohol while use IPA currently and we are moving to a water based cleaning agent with ultrasound. Th

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

The most common rates of in-process cleaning (under wipe) I have encountered are once per 5 to 10 prints. But this depends a on a lot of variables. More often is typically better, but more costly in under-wipe materials. (For some more info see http:

Of course there are solvents which are less harmful to the environment than others. The operative phrase is �less harmful�. As a rule, water-based chemistries are �greener� than solvents. There are some solvent blends designed for aqueous-based eq

Flashback time� Vapor degreasers, although still used in limited applications, no longer represent the conventional wisdom (due to multiple environmental issues). Aqueous-based technologies are the most common method of defluxing. Unlike most va

Hello guys! I have a question for you guys, we have been working with a cleaning agent call Safewash (SWAS) from electrolube, we use this safewash to clean the flux residue from the boards after wave soldering, since or customer doesn't like to have

The latex should not influence your closed-loop filtration - unless of course it falls off during cleaning. The issue would be with water soluble materials. As Dave (hi Dave) said, the clay based version of these will clog/blind/knacker your carbon

Dave is correct. No-clean flux + water = white residue (unless the proper chemical is mixed with the water). Additionally, no-clean flux + IPA = white residue. Many saponifiers work well as do other cleaning agents. White residue may also be a re

Try Avantec Topklean EL-60, can clean off solder paste or uncured glue, is hydrocarbon based cleaner - but with high flash point. Will evapourate faster than water based solutions, not as fast as IPA , but does much better job.

Our latest designs are flip chip on flex based and we have issues with delamination/blistering. We know it is related to our vapor solvent (n-Propyl Bromide based) attacking an inner layer adhesive. Has anyone else ever heard of something like this?
