Acetone (Electronic Grade)
(CH₃)₂CO · CAS 67-64-1
Electronic grade acetone for semiconductor organic pre-clean, photoresist solubility testing, and backend OSAT substrate cleaning. Fast evaporation, broad organic solvency, and ultra-low residue make it the first-choice solvent for front-end organic degreasing and OSAT flux removal.
