A.2 Conformal Coating

The area around the crystal oscillator and the battery backup circuit on the RabbitLink has had the 

Dow Corning silicone-based 1-2620 conformal coating applied. The conformally coated area is 

shown in Figure A.2-1. The conformal coating protects these high-impedance circuits from the 

effects of moisture and contaminants over time.

Figure A.2-1  RabbitLink Areas Receiving Conformal Coating

Any component in the conformally coated area may be replaced using standard soldering proce-

dures for surface-mount components. Apply a new conformal coating afterwards for continued 

protection against the effects of moisture and contaminants.

NOTE: For more information on conformal coatings, refer to Rabbit Semiconductor 

Technical Note 303, “Conformal Coatings.”
