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 Application
Note 1027.
