3. Package Contents
Your AR60 Skeleton Mechanical Keyboard Shell package should include:
- AR60 Skeleton Aluminum Alloy Keyboard Case
- (Additional small parts like screws, rubber feet, etc., may be included but are not explicitly listed by the manufacturer.)
4. Setup and Assembly
The AR60 shell is designed for custom keyboard enthusiasts. Assembly typically involves installing a compatible 60% PCB and switches (not included) into the aluminum case.
4.1 PCB Compatibility
This shell is compatible with most 60% PCBs, including popular models such as DZ60, GH60, Wooting60 HE, Rakka H60, HM66, Night 61, Night 64, mp6+, American Lion mad60, Tarantula win60, Jiadalong gt60, and Wolf Pies 61. Refer to the dimension diagram in Section 2.2 to ensure your PCB's mounting points align with the shell's "123456-hole bitmap".
4.2 Removable USB Block
The AR60 shell features a removable USB block, allowing for flexibility in PCB installation and cable management. This block can be adjusted or removed as needed for your specific PCB and USB port alignment.
4.3 General Assembly Steps (Conceptual)
The following steps outline a typical assembly process. Specific details may vary based on your chosen PCB and switches.
- Carefully unpack all components.
- Ensure your chosen 60% PCB is compatible with the AR60 shell's mounting points.
- Install your switches onto the PCB (if not pre-assembled).
- Position the PCB assembly within the AR60 shell, aligning the screw holes.
- Secure the PCB to the shell using appropriate screws (typically provided with the PCB or plate, not the shell).
- Install keycaps (not included).
- Connect your keyboard to your computer via a USB cable (not included).
5. Operating Instructions
As the AR60 is a keyboard shell, its operation is dependent on the PCB and switches installed within it. Once assembled, connect your custom keyboard to your computer via a USB cable. The functionality (e.g., key mapping, RGB lighting, magnetic switch features) will be controlled by the software and firmware associated with your specific PCB.
6. Care and Maintenance
To ensure the longevity and appearance of your AR60 Skeleton Mechanical Keyboard Shell, follow these care guidelines:
- Cleaning: Use a soft, dry cloth to wipe down the aluminum alloy surface. For stubborn smudges, a slightly damp cloth with mild soap can be used, followed by immediate drying. Avoid abrasive cleaners or solvents.
- Handling: Handle the shell with care to prevent scratches or dents.
- Environmental Conditions: Store the keyboard in a dry environment, away from extreme temperatures and direct sunlight.
6.1 Quality Standards and Expectations
The AR60 shell is manufactured to specific quality control standards. Please note the following regarding cosmetic imperfections:
- Front (Top View) Surface: Minor defects such as pits, trachoma, air holes, or bumps less than 1mm in diameter are permissible, provided they do not exceed 3 locations on the same plane.
- Side and Bottom Surfaces: These surfaces may have 4-6 defects with a diameter less than 0.9mm, spaced less than 5cm apart.
- Finish: From a distance of 30cm, there should be no obvious processing knife lines, scratches, or significant bumps on the appearance surface. Minor chamfering and tiny joint knife lines at workpiece joints are considered normal.
- Internal Surfaces: Due to the nature of mass production and the focus on external aesthetics, internal surfaces are not subject to the same strict QC standards as external surfaces. Normal knife lines, chamfering hanging point corners, or minor bumps on internal surfaces are considered normal phenomena and are not covered under cosmetic defect claims.
7. Troubleshooting
This section addresses common concerns related to the keyboard shell. For issues related to keyboard functionality (e.g., keys not registering, software problems), please refer to the manual for your specific PCB and switches.
7.1 PCB Does Not Fit
- Check Compatibility: Ensure your PCB is listed as compatible (e.g., DZ60, Wooting60 HE).
- Verify Dimensions: Compare your PCB's dimensions and mounting hole layout with the AR60 shell's dimension diagram (Figure 2.2.1).
- Adjust USB Block: The removable USB block (Video 4.2.1) can be adjusted or removed to accommodate different PCB USB port placements.
7.2 Cosmetic Imperfections
Refer to the "Quality Standards and Expectations" in Section 6.1. Minor cosmetic variations are normal for aluminum alloy manufacturing processes. If you believe an imperfection exceeds these standards, please contact customer support with clear photographs.
8. User Tips
- Confirm PCB Model: Always double-check the exact model of your 60% PCB against the list of compatible boards (e.g., Wooting60 HE, DZ60) to ensure a perfect fit.
- Pre-Assembly Check: Before final assembly, dry-fit your PCB into the shell to identify any potential alignment issues, especially with the USB port and mounting holes.
9. Warranty and Support
For any product-related inquiries, technical assistance, or warranty claims, please contact the seller or manufacturer directly. Keep your purchase records handy for faster service.
