Contrast Enhancement
For information on contrast
enhancement, please see
Application Note 1015.
For information on soldering
LEDs, please refer to Application
Note 1027 and Application Note 1060.
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.
