Materials
Procedure
A. Disassembly
- Remove the keycaps
- Remove the shell
- Unscrew the PCB
- Wearing safety glasses, remove the stems from the housings. You can use an unsharpened pencil for this.
-
Remove the stem housings. Use a jimmy and insert it between the tab on top and the metal plate. Repeat on the other tab.
- Remove the stabilizers, including the spacebar stabilizer.
- Disassemble the slider and stabilizer bar.
B. Preparations
-
Prepare the stabilizers:
- DO NOT USE DIELECTRIC GREASE. This will deform stock topre domes.
- Apply TriboSys 3203 to the surface of the stabilizer slider, including the spacebar stabilizer plunger. Apply the absolute thinnest layer that you can.
- Do the same to the surface of the stabilizer housing where the slider comes into contact.
- Install topre silencing rings slipped around the slider with the shiny side up, if available.
- Install the sliders in the housing.
- Install the stabilizer bars.
- Apply liberal amounts of Krytox 206g2 to where the bar acts on the slider.
-
Prepare the slider housings:
- Apply Krytox 205g0 to the housing rails. Use the smallest amount to cover the length of the rail.
- Install topre silencing rings, either to the underside of the housing or slipped around the slider, if available.
- Install the slider into the housing.
C. Assembly
- Align the Unreal Plate Gasket with the underside of the metal base plate, or install the HHKB spacebar gasket to the spacebar stabilizer housing.


- Install the prepared housings and stabilizers housings, ensuring both sides snap into place.
- Using 2 books, elevate the plate and housings off the table enough that the sliders are able to be in the “up” position upside down with the underside of the housings showing.
- Place the domes on the housings. If using BKE domes, ensure the alignment carefully. An easy check is to align the crisscross pattern that the domes have for ventilation.
- Place the capacitive springs on the housings. If using BKE domes, ensure the spring is not “snapped” into the dome but rather resting on top.
- Place DES Landing Pads on the stabilizer housings and spacebar stabilizer housings. FC660C users should not install the spacebar landing pads.


- Lube PCB with a “toothpaste” amount of TriboSys 3203 or other TriboSys or Krytox grease. Using your finger, apply a thin layer to cover the entire board.
- Reassemble the PCB
-
Prepare the shell:
Fill the case with adhesive weights.
Fill the remaining areas with adhesive 1/8” sponge neoprene or sorbothane.

- Replace the shell.
- Test the keyboard.
- Apply MX or Topre O-rings to the keycaps to prevent bottoming out of the keycaps on the plate.
- Replace the keycaps.
