An alternative to soldering and cleaning the display modules is to use sockets. Naturally, 28 pin DIP sockets 7.62 mm (0.300") wide with
2.54 mm (0.100") centers work well for single displays. Multiple display assemblies are best handled by longer SIP sockets or DIP sockets
when available for uniform package alignment. Socket manufacturers are Aries Electronics, Inc., Frenchtown, NJ; Garry Manufacturing,
New Brunswick, NJ; Robinson-Nugent, New Albany, IN; and Samtec Electronic Hardward, New Albany, IN.

Optical Considerations
The 3.683 mm (0.145") high character of the SCD5510XA gives readability up to eight feet. Proper filter selection enhances readability
over this distance.
Using filters emphasizes the contrast ratio between a lit LED and the character background. This will increase the discrimination of differ-
ent characters. The only limitation is cost. Take into consideration the ambient lighting environment for the best cost/benefit ratio for filters.
Incandescent (with almost no green) or fluorescent (with almost no red) lights do not have the flat spectral response of sunlight. Plastic
band-pass filters are an inexpensive and effective way to strengthen contrast ratios. The SCD5510A/2A are red/high efficiency red dis-
plays and should be matched with long wavelength pass filter in the 570 nm to 590 nm range. The SCD55103A/4A should be matched
with a yellow-green band-pass filter that peaks at 565 nm. For displays of multiple colors, neutral density grey filters offer the best compro-
mise.
