Eighty (2022) Build Guide

This guide will help you assemble your new Mode Eighty. The process should take about 1 hour for hotswap builds and 1.5 hours for soldered builds. Prior to assembly, be sure to gather all the necessary parts and tools in your workspace. If you have any questions during assembly, please send us a message using the help widget below or chat with community members in the #build-support channel of our Discord server.

Preparation

Check that you have the required parts and tools listed above and consider installing VIA (VIA is a free software that makes it easy to test your PCB and customize the keymap of your keyboard). We also recommend the following steps to get the most out of your Eighty.

Lubing Stabilizers: This reduces the rattling sounds that stock stabilizers produce. Taeha Types has a video tutorial available here.

Lubing Switches: This dampens the sound of your switches and increases their smoothness. Lubing switches is a time-consuming process, but the results are noticeable. Taeha Types has a video tutorial available for this as well here.

Mounting Styles

The Eighty supports two different internal mounting styles to fine-tune your typing experience.

Isolated Top Mount: Custom-molded silicone plate caps isolate the plate and screws from the top case.

Stack Mount: A custom-cut Poron base supports the plate/PCB assembly against the top case (requires Poron base).

Fasteners

...

There are up to four different types of fasteners used during this build depending on if you have a hotswap or solder PCB. This diagram can be referenced to confirm that you are using the correct ones.

Step 1 - Detach Bottom Case

...
...
  • Carefully place the Eighty facedown.
  • Use the provided 2.5mm hex tool to remove the screws and remove the bottom case from the assembly.

Step 2 - Install Feet

...
.........
  • Align one end of the foot in one corner of the recessed channel, then gently lower the strip into place. Take care not to stretch the foot.
  • Press on the feet to ensure they are properly adhered, smoothing out any raised areas.

Step 3 - Test PCB

...
.........
  • Open VIA, navigate to the Key Tester tab, and enable 'Test Matrix' mode
  • Place the PCB facedown, connect the daughterboard to the PCB, and plug it in.
  • Touch the ends of your tweezers to the metal contacts under each switch position, lighting up each key in VIA. Note that the function key will not light up.
  • In the rare event that keys do not light up, pause your build here and contact support@modedesigns.com.

Step 4 - Attach Daughterboard to Bottom Case

...
......
  • Disconnect the daughterboard cable from the PCB.
  • With the cable connected to the daughterboard, fasten it into the bottom case using the M2x3 screws (four total).
  • Take care to not overtighten the screws, or you may damage the daughterboard.

Step 5 - Install Stabilizers.

...
............
  • Insert the non-threaded end of the stabilizer into the larger cutout on the PCB, then pivot the threaded ends into place.
  • While bracing the front of each stabilizer, screw it into place from the underside of the PCB. Repeat for the remaining stabilizers.

Step 6 - Install Switches (Hotswap)

...
............
  • Before installing your switches, inspect them to ensure the two metal pins on the underside of each switch are straight. Straighten all pins with tweezers if any are bent.
  • If you plan to use the optional plate foam for a more dampened sound, lay it on top of the PCB now.
  • Align the plate with the front of the PCB, and fasten it into place via the standoffs with the black M2x5 flat head screws (eighty total).
  • Insert switches into the plate/PCB. Take care to brace the back of the hotswap socket with a finger while pushing the switches into place with your thumb. Do not apply downward pressure to the surface of the plate itself.
  • Install remaining switches.

Step 6 - Install Switches (Solder)

...
............
  • Before installing your switches, inspect them to ensure the two metal pins on the underside of each switch are straight. Straighten all pins with tweezers if any are bent.
  • Insert switches into the corner positions of the plate. This will help to align the plate with the PCB.
  • If you plan to use the optional plate foam for a more dampened sound, lay it on top of the PCB now. Align the plate with the front of the PCB, and push the corner switches into place
  • Install remaining switches.
  • Solder each of the switches to the PCB.

Step 7 - Confirm Switch Installation

...
.........
  • Check that the plate is not sagging below the tops of the switches.
  • Check that each switch pin is fully seated into the PCB.

Step 8 - Install Plate Caps

...
...
  • Slide the silicone plate caps onto the plate tabs (seven total).

Step 8 - Attach Plate/PCB to Top Case (Isolated Top Mount Only)

...
.........
  • Place the top case facedown.
  • Gently lower the plate/PCB assembly into the top case.
  • Secure the plate to the top case via the tabs along the top and bottom edges with the black M2x5 button head cap screws (seven total).
  • Take care to avoid over tightening screws such that they go past the silicone plate caps.

Step 8 - Insert Plate/PCB into Top Case (Stack Mount Only)

...
.........
  • Place the top case facedown.
  • Gently lower the plate/PCB assembly into the top case using the three alignment posts.
  • Lay the Poron base on the underside of the PCB. Align the cutouts with the hotswap sockets if using the hotswap PCB.

Step 9 - Attach Daughterboard Connector

...
............
  • Hold the bottom case firmly in one hand and align it with the notch on the bottom edge of the top case.
  • While still holding the bottom case, use your other hand to attach the daughterboard cable to the PCB.
  • Close the bottom case onto the top case, ensuring that the cable sits inside the recessed area of the bottom case.

Step 10 - Secure Bottom Case

...
......
  • Fasten the bottom case to the top case with the black M3x12 socket head cap screws (two total).

Step 11 - Install Keycaps

...
......
  • Install your choice of MX-compatible keycaps.

Step 12 - Set macOS layout

...
.........

Step 13 - Program Keymap in VIA/QMK

...
...
  • If using QMK, you may enter bootloader mode by pressing the physical reset button on the board or pressing Fn + Esc.
  • If any of the keys do not actuate properly, it may be due to a bent switch pin during installation. Remove that keycap and switch using a keycap/switch puller. If any metal pins are bent, straighten them with a pair of tweezers.
