@jitvietnam: Why is Removing Grease from PCBAs SO HARD? 😱 1️⃣"Baked" and Aged Grease: Under continuous high operating temperatures, the grease loses its solvents, oxidizes, and undergoes a "baking effect". It becomes heavily solidified, transforming into a rock-hard or stubborn glue-like residue that bonds aggressively to the board. 2️⃣ High Component Density and Micro-gaps: PCBAs have complex architectures with hundreds of tiny, closely-packed components (SMD, ICs). Grease easily penetrates into micro-gaps and capillary spaces beneath component pins, making it completely inaccessible to manual wiping. 3️⃣ High Risk of Damage: * Scrubbing/Scraping: Easily tears microscopic copper traces, breaks fragile pins, or causes Electrostatic Discharge (ESD) that destroys chips. 👉 Therefore, choose JIT's safe and effective grease removal solutions #pcba #smt #dryiceblasting #technology #satisfying
