Not intending to undercut Mike's offer, but to compliment it. Consider asking Heraeus for guidance about cleaning the residues from reflowing your paste. Some NC flux res: * Cannot be cleaned. * Can be cleaned after a relatively short period of tim

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

Hi 'K', We manufacture both batch and inline defluxing equipment so we have no axe to grind with either technology. There are pros and cons associated with both technologies under specific conditions. Batch machines are typically good cleaners but

Dave, First of all, distilled water is not DI water. It is not the same thing. If you require DI water, you should know what quality is expected for your application. For example, for defluxing applications, generally DI water quality exceeding

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
