Soldering/Cleaning

Cleaning agents from the ketone

family (acetone, methyl ethyl ketone,

etc.) and from the chlorinated hydro-

carbon family (methylene chloride,

trichloroethylene, carbon tetrachlo-

ride, etc.) are not recommended for

cleaning LED parts. All these various

solvents attack or dissolve the en-

capsulating epoxies used to form the

package of plastic LED parts.
