Installing the plate in your Sonnet keyboard is a straightforward process that can significantly affect the feel and sound of your typing. Whether you're building a new Sonnet or upgrading an existing one, getting the plate installation right ensures a stable and satisfying experience.

This guide walks you through each step, from gathering your tools to testing the final build. We'll also highlight common mistakes and how to avoid them, so you can complete the installation with confidence.

Understanding the Sonnet Plate and Mounting System

The Sonnet plate is a key component that sits between the PCB and the case, providing a stable surface for the switches. It also influences the typing feel and acoustics. The Sonnet uses a gasket or mounting block system to isolate the plate from the case, allowing for a softer or firmer typing experience depending on your preference.

Before you begin, ensure you have the correct plate for your Sonnet model. The plate should match the layout of your PCB (e.g., ANSI, ISO) and the case's mounting points. If you're unsure, check the product specifications or consult the manufacturer's documentation.

  • Always handle the plate by its edges to avoid bending or scratching it.
  • Work on a clean, flat surface to prevent damage to the plate or PCB.

Tools and Materials You'll Need

To install the Sonnet plate, you'll need the following: a screwdriver (usually Phillips or hex, depending on your case's fasteners), your Sonnet plate, the PCB, the case, and any mounting blocks or gaskets that came with your kit. If you're using aftermarket mounting blocks, ensure they are compatible with the Sonnet.

Having a soft mat or cloth to place your components on can prevent scratches. A switch puller and keycap puller may also be useful if you need to disassemble an existing build.

  • Double-check that you have all fasteners and mounting blocks before starting.

Preparing the Case and PCB

Start by removing any existing components from the case, such as the PCB, plate, or foam. Clean the case interior to remove dust or debris. If your case has a gasket or mounting block system, inspect it for any damage or wear, and replace if necessary.

Place the PCB on a flat surface and ensure the USB port and any other components are aligned with the case's openings. This step is crucial to avoid misalignment later.

  • Check that the PCB's mounting holes align with the case's standoffs or mounting points.

Aligning the Plate with the PCB

Position the plate over the PCB, ensuring that the switch holes align with the PCB's switch pads. The plate should sit flush against the PCB. If you're using stabilizers, install them on the PCB before placing the plate, as they may need to be inserted through the plate's holes.

Once aligned, gently press the plate down to seat it onto the PCB. Avoid forcing it, as this could bend the plate or damage the PCB.

  • Use a switch or a small tool to check that the holes align perfectly before pressing.

Securing the Plate with Mounting Blocks

The Sonnet uses mounting blocks to secure the plate to the case and to customize the typing feel. For a softer, more flexible typing experience, you can use lattice mounting blocks, which are designed with a porous structure to absorb impact. For a firmer feel, solid blocks are a better choice.

Place the mounting blocks in the designated slots on the case, then position the plate assembly on top. Ensure that the blocks are evenly distributed and that the plate sits level. Secure the plate by screwing it into the case, but avoid over-tightening, as this can strip threads or compress the blocks too much.

  • If you're using the Sonnet Mounting Blocks, note that they come in five types, allowing you to mix and match for a customized feel.

Testing the Build

Before fully assembling the keyboard, test the plate and PCB connection by plugging in the PCB and checking for any shorts or misalignments. If you're using a hotswap PCB, insert a few switches to ensure they fit properly through the plate and into the sockets.

Once you've confirmed everything is aligned, continue with the rest of your build, such as adding switches, keycaps, and the case's top frame.

  • Test each switch to ensure it registers correctly before final assembly.

Step-by-Step Installation Process

  1. Prepare Your Workspace: Gather all tools and components, and lay them out on a clean, flat surface. Ensure you have the correct plate and mounting blocks for your Sonnet model. Checkpoint: Verify you have all screws and blocks before starting to avoid interruptions.
  2. Disassemble the Case: If your keyboard is already assembled, remove the keycaps, switches, and any screws holding the case together. Carefully lift off the top frame to expose the plate and PCB. Common mistake: Forgetting to unplug the USB cable before disassembly can cause strain on the port.
  3. Remove the Old Plate (if applicable): Unscrew the mounting blocks or screws that secure the plate to the case. Lift the plate and PCB assembly out as a unit, then separate the plate from the PCB. Checkpoint: Inspect the PCB for any damage or debris before reinstalling.
  4. Install Mounting Blocks: Decide on the desired typing feel and install the appropriate mounting blocks into the case's slots. For a softer feel, use lattice blocks; for firmer, use solid blocks. Common mistake: Using too many or too few blocks can cause uneven plate support.
  5. Align Plate with PCB: Place the plate over the PCB, ensuring all switch holes align with the PCB's switch pads. If using stabilizers, install them before this step. Checkpoint: Gently press the plate down; it should sit flush without force.
  6. Secure the Plate Assembly: Position the plate and PCB assembly into the case, aligning the mounting holes with the blocks. Screw in the fasteners, but do not overtighten. Common mistake: Over-tightening can strip threads or compress the blocks, affecting the feel.
  7. Test and Finalize: Plug in the PCB and test a few switches to ensure proper registration. Then, install the remaining switches, keycaps, and reassemble the case. Checkpoint: If any switch doesn't fit, recheck alignment before continuing.
