  • Cleaner for electronic parts and method for using the same
    Patent number: 6770614
    Abstract: Precision cleaning compositions for electronic and electrical components comprise at least one halogenated, saturated or unsaturated hydrocarbon other than cis-1,2-dichloroethylene; at least one fluorinated saturated or unsaturated hydrocarbon having the formula CnHmFp, wherein 3≦n≦6, 0≦m≦9 and p≧5; at least one fluorinated saturated or unsaturated ether having the formula CaHbOcFd, wherein 3≦a≦6, 0≦b≦9, c≧1, and d≧5; methylal; at least one simple alcohol; and optionally at least one propellant. In a preferred embodiment, the composition comprises trans-1,2-dichloroethylene, methylal, methyl nonafluorobutyl ether, ethyl nonafluoroisobutyl ether and carbon dioxide. The cleaning compositions are environmentally friendly (non-ozone depleting), are strong enough to tackle tough soils yet mild enough for use on plastic components, are non-flammable, have no flash point, and leave no residue on the substrate.
