Abstract

A number of alternative cleaning solvents to CFC 113 which was identified as a ozone-depleting meterial were collected to measure their experimental physecal properties of density, surface tension, Refractive Index, boiling point, pH, viscosity, flash point, and soltbility. They might be classified as aqueous, simi-aqeous, alcohol ketone, and halogen cleaning solvents. The solubilities of abietic acid, a major component of flux used in PCB (Printed Circuit Board) of the electronic indystry, into the cleaning solvents including CFC 113 were determined for comparison. The assorted cleaning solvents have their own advantages and disadvantages. Therefore a end-user carefully needs to choose the best-fit cleaning solvent after the safety, stability, and economics as well as the effectiveness by physical properties of the alternative cleaning solvents are integratedly considered.
