Corrosion X Treatment
For added protection, applying a treatment like Corrosion X can help. This treatment is typically sprayed onto the electronics, creating a thin film that repels water and prevents corrosion. It’s particularly useful for components that are exposed or cannot be enclosed.
Practical Steps to Waterproof Your RC Electronics
Preparing Your Workspace
Before starting the waterproofing process, organize a clean, well-lit workspace. Gather all necessary materials such as silicone conformal coating, a small brush, Corrosion X, and any enclosures you plan to use. Ensure the electronics are powered off and disconnected from any power source.
Application of Silicone Conformal Coating
1. Clean the Surface: Begin by cleaning the electronic components with isopropyl alcohol to remove any dirt or grease. This ensures the coating adheres properly.
2. Apply the Coating: Using a fine brush, apply the silicone conformal coating evenly over the circuit board. Be careful to avoid any connectors or moving parts.
3. Cure the Coating: Allow the coating to cure for the time specified by the manufacturer, typically 24 hours.
Installing in Waterproof Enclosures
1. Test Fit: Place the electronics inside the enclosure to ensure a good fit.
2. Seal the Enclosure: Secure all openings or seams with silicone sealant to prevent water ingress.
3. Regular Checks: Regularly inspect the enclosure for any signs of wear or damage which might compromise its waterproof integrity.
Applying Corrosion X Treatment
1. Spray the Electronics: Lightly spray the electronics with Corrosion X, ensuring even coverage.
2. Allow Drying: Let the treatment dry completely before reassembling or using the electronics.
Specific Considerations for Different Types of RC Electronics
Speed Controllers
Speed controllers, being crucial for the operation of RC cars, require careful waterproofing. Ensure all connections are sealed and consider using shrink wrap in addition to silicone conformal coating for extra protection.
Servos
For servos, focus on sealing the casing and any entry points for wires. Use gaskets or O-rings if available, and apply a thin layer of grease around shafts to prevent water entry while maintaining movement.
Receivers
Encase receivers in balloon-like covers or small waterproof boxes. Seal wire entries with silicone sealant and ensure any vents are covered with breathable waterproof membranes to prevent condensation inside.
Advanced Tips for Maintaining Waterproofing
- Regular Maintenance: Regularly check and maintain the waterproofing measures. Look for cracks, peeling, or any damage in the conformal coating and reapply as necessary.
- Avoid Direct Streams of Water: Even with waterproofing, it’s wise to avoid exposing your RC electronics to direct streams of water, such as from a hose or a faucet, as the pressure can force water through protective layers.
- Test Regularly: Conduct regular tests in controlled wet conditions to ensure the effectiveness of your waterproofing measures before going into more challenging environments.
By following these detailed steps and considerations, you can effectively waterproof RC electronics, ensuring they remain protected against water damage and function optimally in all your adventurous endeavors.
