The process of removing contaminants from a printed circuit board (PCB) is essential for maintaining its functionality and longevity. Residues from manufacturing, handling, and environmental exposure can negatively impact a circuit board’s performance, potentially leading to malfunctions or premature failure. For example, flux left after soldering can be corrosive, while dust and debris can create short circuits or impede heat dissipation.
Maintaining a pristine circuit board offers numerous advantages, including enhanced reliability, increased lifespan, and improved signal integrity. Historically, cleaning methods have evolved from rudimentary manual techniques to sophisticated automated processes, reflecting advancements in PCB manufacturing and the growing demands for high-performance electronics. Proper cleaning also mitigates the risk of electrochemical migration, which can cause conductive filaments to form and create shorts.
