> ### A.2 Conformal Coating

> The areas around the crystal oscillator and the battery backup circuit on the BL2000 have had the Dow Corning silicone-based 1-2620 conformal coating applied. The conformally coated areas are shown in Figure A-2. The conformal coating protects these high-impedance circuits from the effects of moisture and contaiminants over time.

> Figure A-2. BL2000 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 Rabbit Semiconductor Technical Note 303, Conformal Coatings.
