Many small-component PCBs (printed circuit boards) are assembled today with no-clean solder pastes. No-clean solders speed up the manufacturing process by eliminating the need for cleaning circuit boards after reflow. The solder paste did not need removal and stayed in place without any detrimental effect to the function, performance and planned life expectancy of the…

Modern electronics are everywhere in our world, making life better for nearly every person on the planet. And today's electronic components are smaller and more complex than ever before. Manufacturers are squeezing micro components like CSP, flip chip, micro BGA and QFN packages into tighter spaces on the PCBAs. Low standoff components like MOSFETs and…

Modern PCBA cleaning is a challenge. The drive towards miniaturization has long been a goal within the electronics industry. As more advanced electronic applications are designed, which require increased functionality in a smaller package, manufacturers are looking for production methods which will result in a reliable device.The smaller, more densely populated circuit boards required for…

In the finishing industry today, the most common cleaning system is based on water technology. Since the move away from the two most common vapor degreasing solvents (CFC113 and 1-1-1-trichloroethane) over the past decade due to suspected ozone depletion, aqueous cleaning has become a tried-and-true process. But aqueous cleaning systems tend to have large footprints,…

In the finishing industry today, the most common precision cleaning system is based on water technology. This is understandable, because aqueous cleaning has become a tried-and-true process since the elimination of common vapor degreasing solvents due to suspected ozone depletion. But aqueous cleaning systems tend to have large footprints, require significant capital investment, guzzle electricity…

Nearly all of the recent advances in cleaning fluid technology center around developing safe chemistries that meet both cleanliness standards and environmental regulations – meaning they do not contribute to global warming and are not an ozone depleting substance. However, it was not always that way.Prior to 1990sPrior to the 1990s, the two most common…
