Not using microcontroller sockets?
Go to the Microcontroller (headers) page instead!
Test your controller. Before soldering your controller, you’ll want to flash firmware to it to ensure it works. Desoldering a controller is a lot of work, so test its functionality before soldering it!
You can find the instructions on how to flash your controller on Flashing Firmware.
Orienting your controller. Your controller has a top side and a bottom side. The top will have its chip and most other components on it, while the bottom is usually bare (and will often have a logo or other graphic on it). On Aurora kits, the controller will always face with it its chip facing toward the keyboard PCB, so the controller’s back side is facing toward you.
Add tape to hold the sockets in place during soldering.
Solder each corner first.
Then do the rest.
Add tape to prevent solder from seeping in during the pin soldering.
This is important! If you don't tape them at this point, you risk permanently soldering your controller to the socket!
Using Mill-Max pins
Easiest to insert pins using pliers, or alternatively use tweezers. don’t use your fingers, you’ll pierce your skin if you push down on a pin.
It can be a little tricky to determine how deep you need to push them, look at the images below to see if you have inserted them completely.
Make sure you are using tape to prevent the solder from seeping down into the socket.
Using diode legs
Make sure you are using tape to prevent the solder from seeping down into the socket.
