A novel new cleaning fluid from MicroCare has extremely low surface tension which may enable it to out-perform other cleaning choices. One of the biggest barriers to cleaning a surface is a chemical phenomenon known as “surface tension.” In liquids, molecules cling to each other with an “intermolecular cohesive force.” This force is balanced because each molecule is surrounded to it’s neighboring molecules in every direction. But at the perimeter of the liquid some molecules are in contact with a dissimilar material (such as glass, plastic or air) to which they cannot bond. In response, they bind to each other even more strongly. This bonding is surface tension. But high surface tension makes it hard to clean small parts, PCBs with tight stand-offs or inside very small apertures. All things being equal, a cleaner with a lower surface tension will out-perform a cleaner with a higher surface tension. The lowest surface tension of all is the newest innovation from MicroCare, the new Universal Flux Remover.
