Learn the best methods and industry standards for cleaning circuit boards, removing contaminants like dust, flux residues, and corrosion to ensure optimal performance and longevity! Introduction Cleaning circuit boards is an essential maintenance task in electronics engineering! Even the best-designed printed circuit boards (PCBs) can suffer performance issues or failures if contaminants build up on their surfaces. Dust, flux residue from soldering, and corrosion deposits can all disrupt the delicate electrical pathways on a PCB.  For example, a layer of dust can block airflow and insulate heat, causing components to overheat. Dirt combined with humidity can accelerate corrosion on component leads and PCB traces. Flux residues left after soldering are hygroscopic – they absorb moisture – and can […]
