Contrast Enhancement
For information on contrast
enhancement, please see
Application Note 1015.
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.
