Part 3 - Assembling the board
Let's begin with the case.
- Remove the components from the box if not already done.
- Use the supplied hex key to remove the plate screws.
- Remove the plate from the case.
-
If no screw was inserted into the PCB-conducting screw position out of the box, install this screw.
- Flip the case over.
Install the provided rubber feet into the insets.
- If installing the solenoid:
- Install the stabilizers and spacebar pipe onto the plate.
Make sure the spacebar pipe matches the spacebar orientation you are using.
Make sure the stabilizer inserts are oriented the correct way; the wire clip side should be facing away from the switch cutout.
Note: The stabilizers and spacebar pipe will not be rendered in the images below due to not having a 3D model on hand. - Tune and test the switches if not already done.
Snap the switches into the plate.
- Insert the PCB against the switches.
- Solder the switches into place, making sure that the PCB is seated firmly against the switches.
Excessive gaps between the plate and PCB may negatively affect acoustics. - At this stage, it is highly recommended to connect the PCB to a computer to test the functionality of all keys.
Repair any faulty joints and replace any dysfunctional switches. - If installing the solenoid:
- Cut the provided 3M VHB adhesive sheet to cover this side of the solenoid.
Note that the wire exits on the side facing the viewer, and the plunger extends to the left upon powering. - Peel off one side of the VHB and secure it to the solenoid. Peel off the other side but do not adhere to anything.
- Insert the solenoid into the cutout on the inside of the case, so the plunger extends to the left when powered and the wire exits on top. Insert carefully so the side with VHB does not come into contact with the case.
- Align the
frontsolenoidofwithin the cutout. Push the solenoid beam out tothe cutout provided, andverify thatthe solenoidit does indeed strike thetargetsurfaceuponwhenfullfullyextension.extended. - Push the
solenoid's side with VHBsolenoid against thecase,uppersecurelysurfaceadheringto fully adhere ittointo place.
The solenoid should look like this once fully installed at idle, with thecase.beam extending in the direction of the arrow when pushed out.
- Cut the provided 3M VHB adhesive sheet to cover this side of the solenoid.
- Place the provided O-rings atop the four plate mount points.
- If installing the solenoid:
Connect the solenoid to the PCB. - Insert the switch-plate-PCB-stabilizer assembly into the case, taking care so that the O-rings do not move from their positions.
- Install the four plate screws, compressing the O-rings equally.
- Install the keycaps.
Test some keystrokes and verify that they are sent.
Congratulations! You have fully assembled the Lunar II.
Now you are ready for the keymap editing and final remarks.
