Soldering/Cleaning
Cleaning agents from the ketone
family (acetone, methyl ethyl
ketone, etc.) and from the
chlorinated hydrocarbon family
(methylene chloride,
trichloroethylene, carbon
tetrachloride, etc.) are not
recommended for cleaning LED
parts. All these various solvents
attack or dissolve the
encapsulating epoxies used to
form the package of plastic LED
parts.
