Soldering Considerations SCD558XA hand soldered with SN63 solder using grounded iron 260°C. Wave soldering also possible following these conditions: Preheat that does exceed 93°C solder side board package surface temperature 85°C. Water soluble organic acid flux (except carboxylic acid) rosin-based flux without alcohol used. Wave temperature 245°C ±5°C with dwell between sec. sec.

Optical Considerations 0.145" high character SCD558XA gives readability eight feet. Proper filter selection enhances readability over this distance. Using filters emphasizes contrast ratio between character background. This will increase discrimination different characters. only limitation cost. Take into consideration ambient lighting environment best cost/benefit ratio filters. Incandescent (with almost green) fluorescent (with almost red) lights have flat spectral response sunlight. Plastic band-pass filters inexpensive effective strengthen contrast ratios. SCD5580/2A red/high efficiency displays should matched with long wavelength pass filter range. SCD5583/4A should matched with yellow-green bandpass filter that peaks displays multiple colors, neutral density grey filters offer best compromise.
Additional contrast enhancement gained shading displays. Plastic band-pass filters with built-in louvers offer next step contrast improvement. Plastic filters improved further with anti-reflective coatings reduce glare. trade-off fuzzy characters. Mounting filters close display reduces this effect. Take care overheat plastic filter allowing proper flow. Optimal filter enhancements gained using circular polarized, anti-reflective, band-pass filters. circular polarizing further enhances contrast reducing light that travels through filter reflects back display less than Several filter manufacturers supply quality filter materials.
