In the production of electronic products, PCBA is a crucial link. It is like the "heart" of electronic equipment, carrying various electronic components and circuits. However, after the completion of processes such as welding and patching, contaminants such as flux, tin slag, and dust often remain on the PCBA board. These seemingly tiny impurities, if not cleaned in time, may cause product short circuits, corrosion, and malfunctions, seriously affecting service life and reliability. Therefore, water-based PCBA cleaning agents have become the "standard" process products in the cleaning process of electronic manufacturing.
Application of water-based PCBA cleaning agents
Water-based PCBA cleaning agents, as the name suggests, are water-based cleaning liquids with appropriate amounts of surfactants, corrosion inhibitors, and other auxiliary ingredients. The biggest difference between it and traditional solvent-based cleaning agents is that water-based is environmentally friendly, safe, and non-flammable.
Water-based cleaning agents are more friendly to the human body and the environment. Many traditional solvent-based cleaning agents contain volatile organic compounds (VOCs), which not only have a pungent smell, but also easily affect the health of operators. Water-based PCBA cleaning agents have a slight odor and meet environmental protection requirements. Workers can use them with more peace of mind, and the air quality in the workshop is easier to meet standards.
Secondly, the cleaning ability of water-based PCBA cleaning agents is not inferior. Modern water-based formulas can effectively remove pollutants such as solder paste residues, flux residues, and tiny particles. Especially when used with ultrasonic cleaning equipment, the cleaning effect is better, and it can penetrate into the bottom of complex packages such as BGA and QFN to ensure that the circuit board is clean and residue-free.
In addition, from a cost perspective, although water-based cleaning agents may need to be paired with special cleaning equipment in the early stage, in the long run, their operating costs are low, maintenance is simple, and there is no need to frequently change the cleaning fluid, so the cost performance is very high.
At present, as electronic products develop towards high density, miniaturization, and high performance, the requirements for cleanliness are getting higher and higher. Mobile phones, automotive electronics, medical devices, military equipment and other fields have particularly strict requirements for PCBA cleaning. At this time, water-based PCBA cleaning agents have become the ideal choice for more and more electronic manufacturing companies with their high efficiency, environmental protection, and safety.
