A.2 Conformal Coating
The areas around the crystal oscillator and the battery backup circuit on the PowerCore module have had
the Dow Corning silicone-based 1-2620 conformal coating applied. The conformal coating protects these
high-impedance circuits from the effects of moisture and contaminants over time.
The conformally coated area on the PowerCore module is on its bottom side. This area is inaccessible
when the module is attached to the RabbitFLEX base board. Under normal circumstances, there is no need
to access it. Any components in the conformally coated area may be replaced using standard soldering pro-
cedures for surface-mounted components. A new conformal coating should then be applied to offer con-
tinuing protection against the effects of moisture and contaminants.
The PowerCore FLEX User’s Manual contains further information and an illustration of the conformally
coated area.
NOTE: For more information on conformal coatings, refer to Rabbit Technical Note 303,
“Conformal Coatings.”
