Excuse me: What is the difference between acetone and isopropanol as cleaning agents?
Our company uses these three products to clean bare dies. Their activities are acetone, isopropanol and alcohol, but generally speaking, when cleaning, you'd better take a spot and try not to react first! Then wash a lot! However, these solvents have little effect on people's health ... so it is not good to use alcohol directly. Ha ha ha ha activity is acetone and isopropanol. In alcohol learning, it seems that isopropanol cleaning of acetone-induced liver injury is very important in semiconductors. Acetone volatilizes too quickly. We seem to have learned more with IPA! ! ! ! ! ! ! ! ! ! ! ! ! ! 1 1IPA is isopropanol. Isopropyl alcohol, I don't think we need it here. I don't need it here either. I use acetone. Isopropanol is used for dehydration, which is cheaper than alcohol, so it is used more, but attention should be paid to purity and it should be recycled frequently. Acetone has better deoiling effect and less toxicity than benzene. It is only used for scrubbing equipment. IPA is used for drying after cleaning. Acetone is usually used to scrub machines or parts, not to clean them. The volatility of IPA, that is, isopropanol, makes acetone suitable for cleaning. Acetone is now a precursor chemical controlled by the Public Security Bureau. We use isopropanol to dehydrate and clean, and acetone is the best solvent to clean the oil stain, and the effect of cleaning the watermark is very good.
