Hi Carl / Bill, I seem to miss your point regarding disclosure. As I CLEARLY stated, it is the perception of damage more than the possibility of damage. As a twenty year veteran of de-fluxing systems, I can assure you that there remains enough con

There are several manufacturers of batch-format de-fluxing systems. Here is a list of them: Aqueous Technologies http://www.aqueoustech.com (909) 944-7771 Batch and Inline UnitDesign http://www.unitdesign.com (714) 672-9944 Batch Austin American T

Although water soluble (OA) flux is technically the easiest flux to remove, it is also the most damaging type of flux if not removed. A dishwasher lacks the pressure and nozzle design to produce the very small water particle size required for thorou

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

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

Hi Jeff, Sean is correct. Although ultrasonic technology will work in post-reflow de-fluxing applications, you will receive concerns regarding ultrasonic �damage� to wire bonded components. Much has been written to combat this belief but the conce

First, you must determine a few things: 1. What specific de-fluxing chemical are you going to use? Basic required determinations include the chemical�s pH, is it a VOC (if so, what is its VOC content), what concentration is the chemical used in (1
