Opening the Drone With Flat Flex PCB

 

Remove Propellers and Battery

Start by removing all propellers from your DJI Mavic Pro. Hold each motor firmly and unscrew the propellers one at a time. Place them in a safe container to avoid losing any parts. Next, slide the battery release buttons and lift the battery out of the drone. Set the battery aside in a secure spot.

Tip: Removing the propellers and battery prevents accidental power-up and protects you from injury during the repair.

 

Unscrew Upper Shell

You will need your precision screwdriver set for this step. Locate all screws on the upper shell of your drone. Most screws sit near the arms and under the stickers. Use a plastic pry tool to gently lift any stickers that cover screws. Place each screw in a small container or on a magnetic mat as you remove them.

Check the following areas for screws:

• Near each motor arm
• Under the rear arms
• Around the battery compartment

Take your time and make sure you do not strip any screws. If a screw feels stuck, apply gentle pressure and try a different screwdriver size.

 

Detach Shell Carefully

Once you remove all screws, use a plastic pry tool to separate the upper shell from the lower body. Start at one corner and work your way around the drone. Move slowly to avoid cracking the plastic. You may hear small clicks as the shell releases from the clips inside.

Lift the upper shell gently. Watch for any cables or connectors attached to the shell. If you see a cable, disconnect it carefully using tweezers. This step gives you clear access to the gimbal and the flat flex pcb inside your drone.

Note: Take a photo of the inside before you continue. This will help you remember where each cable and connector belongs during reassembly.

By following these steps, you prepare your drone for the next stage of the flat flex pcb replacement. Stay organized and patient to avoid damaging any components.

 

Accessing the Gimbal By Flat Flex PCB

Clean Gimbal Area

You need to keep the gimbal area clean before you handle any internal parts. Dust and debris can cause problems during the repair. Use a can of compressed air to blow away loose particles from the gimbal and surrounding components. Hold the can upright and spray short bursts to avoid moisture buildup.

Take a soft, lint-free cloth and gently wipe the gimbal arms and camera housing. Avoid using excessive force. If you see stubborn dirt, use a small amount of isopropyl alcohol on the cloth. Make sure the area dries completely before you continue.

Tip: Cleaning the gimbal area reduces the risk of static discharge and accidental damage to sensitive electronics.

 

Locate Flat Flex PCB

After cleaning, you need to find the flat flex pcb inside your DJI Mavic Pro. The flat flex pcb connects the gimbal to the main board. Look for a thin, flexible ribbon cable that runs from the gimbal assembly toward the main circuit board.

Follow these steps to locate it:

1. Examine the area around the gimbal mount.
2. Identify the ribbon cable with multiple gold contacts at each end.
3. Trace the cable to its connectors on both the gimbal and the main board.

You may see the cable secured with small clips or adhesive. Take note of how the cable routes through the drone. You will need to install the new cable in the same way.

Note: Take a clear photo of the cable’s path and connectors. This reference will help you during reassembly.

Once you locate the flat flex pcb, you are ready to move on to the removal process. Careful observation and documentation at this stage will make the rest of the repair much easier.

 

Removing the Flat Flex PCB

Disconnect Ribbon Cable

You must approach this step with patience and a steady hand. The ribbon cable connects the gimbal to the main board and uses delicate connectors that can break if handled roughly. Follow these steps to disconnect the ribbon cable safely:

1. Expose the two small ZIF (Zero Insertion Force) connectors near the front of the board. Remove any plastic coverings that protect these connectors.
2. Use a nylon spudger to gently lift the locking tabs on each ZIF connector. Avoid using metal tools, as they can damage the contacts.
3. Carefully slide the ribbon cable out of each connector. Hold the cable by its reinforced ends, not by the thin flexible part.

Tip: Take your time with the connectors. If you feel resistance, double-check that the locking tab is fully open before pulling the cable.

If a cable feels stuck, do not force it. Inspect the connector for any remaining adhesive or debris. Sometimes, a small amount of dust or glue can make removal difficult. Use a soft brush or compressed air to clear the area. If the cable still does not move, gently wiggle it side to side while applying minimal pressure.

 

Remove Old PCB

Once you disconnect the ribbon cable, you can remove the old flat flex pcb from the drone. The board may be secured with small screws or clips. Use your precision screwdriver to remove any screws, placing them in your parts container for safekeeping. If you encounter clips, release them gently with a plastic pry tool.

Lift the old pcb out of its slot. Avoid bending or twisting the board, as this can damage nearby components. If adhesive holds the pcb in place, apply gentle, even pressure to loosen it. Never use excessive force.

Note: If the pcb does not come out easily, double-check for hidden screws or clips. Take another look at your reference photos to ensure you have not missed anything.

Handle the removed pcb carefully. Place it on an anti-static mat or in a safe container. Inspect the area for any leftover debris or damage before proceeding to install the new part.

By following these steps, you protect the sensitive connectors and ensure a smooth transition to the next phase of your repair. Careful handling at this stage prevents costly mistakes and keeps your DJI Mavic Pro in top condition.

 

Installing the New Flat Flex PCB

 

Align and Connect PCB

You have removed the old board and prepared the area. Now, you need to install the new flat flex pcb. Start by comparing the new board with the old one. Check the connectors, shape, and contact points. This step helps you avoid mistakes during installation.

Hold the new board by its reinforced edges. Avoid touching the gold contacts. Align the board with the mounting points inside your drone. The connectors should face the same direction as before. Use your reference photos to guide you.

Gently slide the ribbon cable ends into the ZIF connectors. Make sure the cable sits straight and flat. If you feel resistance, stop and check the alignment. Forcing the cable can damage the contacts.

Tip: Use tweezers for better control when positioning the cable. This tool helps you avoid bending or creasing the ribbon.

Once the cable is in place, press down the locking tabs on the ZIF connectors. You should hear or feel a soft click. This sound means the connection is secure.

 

Secure Connections

After connecting the ribbon cable, you need to secure the new board. If your drone uses screws, insert them by hand first. Tighten them with a precision screwdriver. Do not overtighten, as this can crack the board or strip the threads.

If your model uses clips, press the board gently until you hear a snap. Double-check that the board sits flat and does not move. A loose board can cause connection problems later.

Inspect all connections. Make sure the ribbon cable follows the same path as before. The cable should not twist or stretch. Use a small piece of tape if needed to hold the cable in place, but avoid covering any contacts.

Note: Before closing the shell, check that no tools or loose screws remain inside the drone. A clean workspace prevents accidental damage during reassembly.

Take a final look at your work. Confirm that every connector is locked and every screw is tight. This careful inspection ensures your drone will function correctly when you power it on.

If you follow these steps, you will have a properly installed flat flex pcb. You are now ready to reassemble your DJI Mavic Pro and move on to testing.

 

Reassembly

Reattach Shell

Begin by aligning the upper shell with the lower body of your DJI Mavic Pro. Check that all internal cables sit properly and do not get pinched between the shells. Lower the shell gently, starting from the rear and moving forward. Press along the edges until you hear the clips snap into place. If you feel resistance, lift the shell slightly and check for misaligned parts or trapped wires.

Tip: Refer to your earlier photos to confirm cable positions before closing the shell.

 

Replace Screws and Propellers

Once the shell sits securely, locate the screws you removed earlier. Use your magnetic mat or container to find the correct screws for each location. Insert the screws by hand to avoid cross-threading, then tighten them with your precision screwdriver. Do not overtighten, as this can strip the plastic.

Follow this checklist for reassembly:

• Secure all screws around the arms and battery compartment.
• Reattach any stickers that cover screw holes.
• Install the propellers by matching each one to its correct motor. Push down and twist to lock them in place.

 

Final Safety Check

Before you power on your drone, perform a thorough safety check. Inspect the shell for gaps or loose edges. Confirm that all screws are tight and all propellers spin freely. Check that no tools or foreign objects remain inside the drone.

⚠️ Note: Never skip the safety check. A missed step can cause damage during your first test flight.
