I would be far more concerned about the flux residue intentionally left on the board than the �dust bunnies� sticking to the flux. In �perfect� no-clean applications, flux residue, although present, is nearly invisible and marginally conductive. In

The answer depends on the cleaning / defluxing method. There are many fine chemicals available. One must first consider the cleaning method, then safety (environment and operator), then cost. For automated board cleaners (defluxers), consider th

Dave, I would not recommend use of a multi-meter to determine high quality DI water resistivity readings. There are a number of reasons including a multi-meter�s lack of temperature compensation. We use a Myron-L resistivity meter to accurately de

The best method of cleaning misprinted boards is with a stencil cleaner. I would not recommend the use of a spray-in-air system for misprints. Spray systems can cause solder paste to become embedded into vias and under components (if double sided).

There are a number of �low cost� stencil cleaners available. I am a manufacturer of one but I'll list a variety and let the others provide editorial on which is best. Basically, there are three technologies, manual cleaning (solvents and wipes), ul

Most ionic contamination testers prompt the operator for the current concentration at the start of each cycle. The normal concentration is 25% DI Water and 75% IPA. Although most machines ask for the current concentration, concentration adjustments

As with so many things, some brands work very well on high density, low profile assemblies and some do not. Because my company manufactures these machines, I don't want to use this forum as an advertisement so I will recommend the following: 1. Sen

The ICOM 5000 was made by Trek Industries. The company was purchased by Stoelting. I don't think they make or support these machines anymore. By the way, the correct formula for area is Length X Width X 2 (X 1.3 or 1.5 based on component geography)
