Have you tried an ultrasonic water cleaning process? We use an ultrasonic cleaner with tap water and Omega Aqua Clean LPH cleaner (omegasonics.com) then rinse with DI water. However, our cleaning requirements are not as strict as yours are from the

Hello all, We have an old batch cleaning machine in our production and we use isopropanol alcohol during the rinsing process probably to lower the surface tension. Right now we are looking for a new machine who can do a better job compare to the ol

Thanks guys, But for the cleaning process we already have a chemical product to clean flux residues and other contaminant. But it seems that we can't rinse properly under low stand-off components and we find trace of our chemical under some ceramic c

My company currently uses water soluble paste for our SMT process. We were having trouble retaining hot water in our in line, closed loop DI cleaner. The cleaner kept shutting down when the water temp. dropped below 125C. As a result, the conveyor

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

This is one of the most common questions I get asked. Why clean no-clean flux. It was stated earlier that no-clean residues are benign. This may or may not be accurate. It depends on several factors including the reflow process. In a perfect world, t

Hello, I have a question on white residues formation at wave soldering. We have recently run experiments to test the performance of various halide-free water soluble fluxes (ORH0 under JSTD-004). The flux was applied through a spray fluxer and all P
