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 of these various solvents attack or dissolve
the encapsulating epoxies used to form the package of
plastic LED parts.
For information on soldering LEDs, please refer to Appli-
cation Note 1027.
