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
