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, trichloroeth-
ylene, 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.
