Step-by-Step Guide to Soldering the AOS 3.5 GEP-F722
1. Mounting the Flight Controller
Secure the AOS 3.5 GEP-F722 to your drone frame using soft mounts to decrease vibrations.
2. Pre-Tinning Pads and Wires
Apply a tiny quantity of solder to the pads and wire ends to guarantee a firm connection.
3. Connecting Power Wires
Solder the main power leads to the “+” and “-” pads on the flight controller.
4. Soldering Motor Wires
Connect the motor wires to the relevant pads on the ESC and double-check polarity.
5. Adding Peripheral Components
Attach the receiver, VTX, and other peripherals to the UART ports.
Advanced Soldering Techniques
Dealing with Micro Pads
Use a magnifying glass or microscope for accurate soldering on small pads.
Troubleshooting Cold Solder Joints
Reheat and add a little quantity of flux to mend weak connections.
Testing Your Connections
Checking Continuity
Use a multimeter to confirm all connections are solid and there are no short circuits.
Using a Multimeter for Accuracy
Test the resistance and check the power output for each connection.
Troubleshooting Common Issues
Identifying Poor Connections
A dull or broken solder junction is generally an indication of a faulty connection.
Fixing Solder Bridges
Remove excess solder using desoldering braid or a solder sucker.
Safety Tips for Soldering
Avoiding Burns and Fumes
Always operate in a well-ventilated location and use protection gear.
Proper Ventilation and Handling
A fume extractor is vital to protect oneself from dangerous vapors.
Maintenance of Soldering Tools
Cleaning the Soldering Iron Tip
Wipe the tip with a moist sponge to remove residue after each usage.
Storing Tools Properly
Store your instruments in a dry and secure area to extend their longevity.
