¶ Technical Manual – Carvera Air Mainboard Replacement & Breakdown
¶ 1. Tools & Safety Precautions
¶ Tools Required:
3mm Allen key
2mm Allen key
#2 Pozi screwdriver
¶ Safety Precautions:
✔ Ensure the machine is powered off before proceeding.
✔ Unplug all cables before beginning the disassembly.
¶ 2. Removing the Existing Mainboard
¶ 2.1 Removing the Rear Cover
Using a screwdriver, unscrew and remove the top rear cover (Figure 1).
¶ 2.2 Unscrewing the Socket Cluster (Optional, for better access)
Remove the four screws securing the socket cluster.
This step is not mandatory but provides better access to the mainboard (Figure 2).
¶ 2.3 Disconnecting Cables & Wi-Fi Antenna
Unplug the USB cables first.
Carefully remove the Wi-Fi antenna using bent tweezers (Figure 3).
Work around the mainboard, unplugging all connectors:
Each connector has security clips on the sides that must be pressed before unplugging (Figure 4).
¶ 2.4 Removing the Mainboard Screws
The mainboard is secured by four screws (one at each corner).
Use a 3mm Allen key to unscrew them carefully (Figure 5).
Avoid dropping screws, as they may cause damage.
"A dropped part will always land where it can do the most damage." – Sod/Murphy’s Law
¶ 2.5 Transferring Components to the New Mainboard
Remove the SD card and drivers from the old mainboard.
Install them onto the new mainboard (Figure 5).
¶ 3. Installing the New Mainboard
¶ 3.1 Mounting the Mainboard
Align the new mainboard in place.
Secure it with screws using a 3mm Allen key.
¶ 3.2 Reconnecting the Wi-Fi Antenna
Use tweezers to position the Wi-Fi antenna over its socket.
Keep it parallel to the mainboard, then press it firmly into place.
A flat-end Allen key works well for this task.
¶ 3.3 Reconnecting All Cables
Starting from the right side, reconnect each cable to its corresponding header.
Use the diagram in Figure 5 for reference.
