A.5 Conformal Coating
The areas around the 32 kHz real-time clock crystal oscillator on RCM3700 RabbitCore
modules without mounting holes have had the Dow Corning silicone-based 1-2620 con-
formal coating applied. The conformally coated area is shown in Figure A-5. The confor-
mal coating protects these high-impedance circuits from the effects of moisture and
contaminants over time. The new design used on RCM3700 RabbitCore modules with
mounting holes do not need a conformal coating.
Figure A-5. RCM3700 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.
NOTE: For more information on conformal coatings, refer to Technical Note 303, Con-
formal Coatings.
