A.5 Conformal Coating
The areas around the 32 kHz real-time clock crystal oscillator have had the Dow Corning
silicone-based 1-2620 conformal coating applied. The conformally coated area is shown
in Figure A-6. The conformal coating protects these high-impedance circuits from the
effects of moisture and contaminants over time.
Figure A-6. RCM4400W 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.
