6.3 Conformal Coating
The areas around the crystal oscillator and the battery backup circuit on the CPU Card
have had the Dow Corning silicone-based 1-2620 conformal coating applied. The confor-
mally coated areas are shown in Figure 22. The conformal coating protects these high-
impedance circuits from the effects of moisture and contaminants over time.
Figure 22. CPU Card Areas Receiving Conformal Coating
Any components in the conformally coated area may be replaced using standard soldering
procedures for surface-mounted components. A new conformal coating should then be
applied to offer continuing protection against the effects of moisture and contaminants.
