The time average luminous
intensity may be adjusted for
operating ambient temperature by
the following exponential
equation:
immersion time in the vapors of
less than two (2) minutes
Mechanical
These light bar devices may be
operated in ambient temperatures
above + 60°C without derating
when installed in a PC board
configuration that provides a
thermal resistance pin to ambient
value less than 280°C/W/LED. See
Figure 2 or 7 to determine the
maximum allowed thermal
resistance for the PC board,
RθPC-A, which will permit
maximum. Some suggested vapor
cleaning solvents are Freon TE,
Genesolv DES, Arklone A or K. A
60°C (140°F) water cleaning
process may also be used, which
includes a neutralizer rinse (3%
ammonia solution or equivalent),
a surfactant rinse (1% detergent
solution or equivalent), a hot
water rinse and a thorough air
dry. Room temperature cleaning
may be accomplished with Freon

To optimize device optical
performance, specially developed
plastics are used which restrict
the solvents that may be used for
cleaning. It is recommended that
only mixtures of Freon (F113)
and alcohol be used for vapor
cleaning processes, with an
Example:
