Chemicals, specially solvents, are used for cleaning and degreasing of electronic components and printed circuit boards (PCBs) to remove contaminants like oils, fluxes, and residues from soldering processes. This ensures proper functioning and longevity of the components. Moreover they are also used in the formulation of coatings and adhesives that protect electronic components from moisture, dust, and other environmental factors. They help in applying these materials evenly and then evaporate, leaving a protective layer. Some chemicals are used as coolants in electronic systems, helping to manage heat generated by electronic components. Solvents are also used in various testing and inspection processes to ensure the quality and reliability of electronic components.
