Soldering

Diodes

Orientation: Black bar facing downwards or towards the footprint indicator.

1. Solder one pad.
2. While holding diode with tweezers, reflow solder and place diode down on pad.
3. Solder other pad.

• Note, when working with MELF package diodes, you may need to reflow and add more solder a couple times before an adequate connection is made.

LEDs

Orientation: Notched corner/pin facing the pad marked with rectangle. This applies for both SK6812 Mini-E & WS2812B LEDs.

• Notes: \ - This component is heat sensitive. Be cautious and work at a safe temp (~300c). \ - It is wise to test the LEDs as you solder then. Consider soldering your controllers beforehand. \ - The LED order is somewhat outlined and should be followed in order when building.

1. Solder one pad. (it may be easier to solder all 4 pads before placing LED down when installing WS2812B LEDs)
2. While holding LED with tweezers, reflow solder and place LED down on pad.
3. Solder remaining pads.

Hotswap sockets

1. Solder one pad.
2. While holding hotswap socket (fingers are fine), reflow solder and place socket down on pad.
3. Solder other pad.

• Note, don't hesitate to use a little extra solder, as that will help secure the socket and prevent it from being ripped off.

Microcontrollers

Orientation: Both microcontrollers CONTROLLERPLACEMENT.

• Note, it is recommended to flash each microcontroller prior to soldering. See firmware section for more.

1. Insert headers from front, solder in from the back.
2. Place microcontroller CONTROLLERPLACEMENT.
3. Apply solder to all pins.
4. Use flush cutters or similar to trim excess from pins on each side.

Misc.

Reset switches

1. Solder one pad.
2. While holding switch with tweezers, reflow solder and place switch down on pad.
3. Solder remaining pads.
