Electrical and Mechanical Considerations
Voltage Transient Suppression
We recommend that the same power supply be used for the dis-
play and the components that interface with the display to avoid
logic inputs higher than V
transients in the power supply line while they change display
states. The common practice is to place .01 mF capacitors close to
the displays across V
10 mF capacitor for every second display.
ESD Protection
The silicon gate CMOS IC of the DLX3416 is quite resistant to
ESD damage and capable of withstanding discharges greater than
2.0 kV. However, take all the standard precautions, normal for
CMOS components. These include properly grounding personnel,
tools, tables, and transport carriers that come in contact with
unshielded parts. If these conditions are not, or cannot be met,
keep the leads of the device shorted together or the parts in
anti-static packaging.
Soldering Considerations
The DLX3416 can be hand soldered with SN63 solder using a
grounded iron set to 260°C.
Wave soldering is also possible following these conditions: Pre-
heat that does not exceed 93°C on the solder side of the PC board
or a package surface temperature of 85°C. Water soluble organic
acid flux (except carboxylic acid) or rosin-based RMA flux without
alcohol can be used.
Wave temperature of 245°C ±5°C with a dwell between 1.5 sec. to
3.0 sec. Exposure to the wave should not exceed temperatures
above 260°C for five seconds at 0.063" below the seating plane.
The packages should not be immersed in the wave.
Post Solder Cleaning Procedures
The least offensive cleaning solution is hot D.I. water (60 °C) for
less than 15 minutes. Addition of mild saponifiers is acceptable.
Do not use commercial dishwasher detergents.
For faster cleaning, solvents may be used. Carefully select any sol-
vent as some may chemically attack the nylon package. Maximum
exposure should not exceed two minutes at elevated tempera-
tures. Acceptable solvents are TF (trichorotribluorethane), TA, 111
Trichloroethane, and unheated acetone.
Note:
Unacceptable solvents contain alcohol, methanol, methylene chlo-
ride, ethanol, TP35, TCM, TMC, TMS+, TE, or TES. Since many com-
mercial mixtures exist, contact a solvent vendor for chemical
composition information. Some major solvent manufacturers are:
Allied Chemical Corporation, Specialty Chemical Division, Morris-
town, NJ; Baron-Blakeslee, Chicago, IL; Dow Chemical, Midland, MI;
E.I. DuPont de Nemours & Co., Wilmington, DE.
For further information refer to Appnotes 18 and 19 at

An alternative to soldering and cleaning the display modules is to use
sockets. Standard pin DIP sockets .600" wide with 0.100" centers
work well for single displays. Multiple display assemblies are best
handled by longer SIP sockets or DIP sockets when available for uni-
form package alignment. Socket manufacturers are Aries Electronics,
Inc., Frenchtown, NJ; Garry Manufacturing, New Brunswich, NJ; Rob-
inson-Nugent, New Albany, IN; and Samtec Electronic Hardware,
New Albany, IN.

Optical Considerations
The 0.270" high characters of the DLX3416 gives readability up to
eight feet. Proper filter selection enhances readability over this dis-
tance.
Filters enhance the contrast ratio between a lit LED and the char-
acter background intensifying the discrimination of different char-
acters. The only limitation is cost. Take into consideration the
ambient lighting environment for the best cost/benefit ratio for fil-
ters.
Incandescent (with almost no green) or fluorescent (with almost no
red) lights do not have the flat spectral response of sunlight. Plas-
tic band-pass filters are an inexpensive and effective way to
strengthen contrast ratios.
The DLR3416 is a standard red display and should be matched
with long wavelength pass filter in the 600 nm to 620 nm range.
The DLO3416 is a high efficiency red display and should be
matched with a long wavelength pass filter in the 470 nm to
590 nm range. The DLG3416 should be matched with a yel-
low-green band-pass filter that peaks at 565 nm. For displays of
multiple colors, neutral density gray filters offer the best compro-
mise.
Additional contrast enhancement is gained by shading the dis-
plays. Plastic band-pass filters with built-in louvers offer the next
step up in contrast improvement. Plastic filters can be improved
further with anti-reflective coatings to reduce glare. The trade-off is
fuzzy characters. Mounting the filters close to the display reduces
this effect. Take care not to overheat the plastic filter by allowing for
proper air flow.
Optimal filter enhancements are gained by using circular polar-
ized, anti-reflective, band-pass filters. Circular polarizing further
enhances contrast by reducing the light that travels through the fil-
ter and reflects back off the display to less than 1%.
Several filter manufacturers supply quality filter materials. Some of
them are: Panelgraphic Corporation, W. Caldwell, NJ; SGL Homa-
lite, Wilmington, DE; 3M Company, Visual Products Division, St.
Paul, MN; Polaroid Corporation, Polarizer Division, Cambridge,
MA; Marks Polarized Corporation, Deer Park, NY, Hoya Optics,
Inc., Fremont, CA.
One last note on mounting filters: recessing displays and bezel
assemblies is an inexpensive way to provide a shading effect in
overhead lighting situations. Several Bezel manufacturers are:
R.M.F. Products, Batavia, IL; Nobex Components, Griffith Plastic
Corp., Burlingame, CA; Photo Chemical Products of California,
Santa Monica, CA; .E.E.-Atlas, Van Nuys, CA.
