Guo: You want to know: 1 Can I use water as the solvent in an ultrasonic machine to remove solder paste from PCB? Continuing from Jason�s comments: Sure you can use water as the solvent to remove solder paste from PCB, but recognize that some flu

The use of IPA in automated defluxing systems is nearly extinct for the following reasons: 1. IPA is flammable. In a spray-in-air environment, the already low flashpoint is even lower. 2. IPA is not a great solvent. There are specific containme

Ryan, Another option to look at would be ultrasonic cleaning if your boards/process would allow it. Automated multi-tank models with wash, rinse and dry capability are available for larger throughput. Typically both wash and rinse tanks have ultra

RK, what are you trying to remove? What are you trying to remove it from? And, what type of equipment do you have? Generically, I suggest a saponifier, related to other aqueous chemistries, is associated with: -- higher PH -- need for effective che

What low profile components are you dealing with? We have had problems with cleaning under leadless chip carriers using an aquastorm 200 with Kyzen Aquanox 4520T and the general concensus is that you will not clean under this type of device with an

I'm using urethane conformal coat and have fisheyes and dewetting after coating even though the PWAs have been through the wash cycle twice. I'm looking at using Ionox 13302 in an ultrasonic cleaner as a short term solution until root cause can be id
