Soldering/Cleaning
Cleaning agents from the ketone family (acetone, methyl
ethyl ketone, etc.) and from the chlorinated hydrocarbon
family (methylene chloride, trichloro-ethylene, 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 Applica-
tion Note 1027.
