If something is missing from here, it's not really important.
At some point, you'll have to upload design files to the production company. Send them the zip files in [the source](https://github.com/ploopyco/mouse/tree/master/hardware/Electronics/Gerbers) **TODO fix this link**. That should contain everything you need to get the boards made. If the production company rejects this package, however, you'll need to address the issue yourself.
At some point, you'll have to upload design files to the production company. Use the [electronics source files](https://github.com/ploopyco/nano-trackball/tree/master/hardware/electronics) to generate manufacturing files (you'll have to convert them from their native Altium format if you're using some other platform). That should contain everything you need to get the boards made. If the production company rejects this package, however, you'll need to address the issue yourself.
## Step 2: Order the electronics components
All of the components are described in [the schematics of the PCBs](https://github.com/ploopyco/trackball/tree/master/hardware/Electronics/Schematics) **TODO fix this link**. Ordering the components is left as an exercise for the reader. Here are a few tips:
All of the components are described in the schematics of the PCBs. Ordering the components is left as an exercise for the reader. Here are a few tips:
- We used Alibaba to order ADNS-5050 sensors
- Digikey and Mouser carry all of the other electrical components

Schematics can be found in [the source](https://github.com/ploopyco/mouse/tree/master/hardware/Electronics/Schematics) **TODO fix this**.
## Step 4: Solder the components to the boards
Once you've got the PCBs and all of the components, print out [the schematics](https://github.com/ploopyco/mouse/tree/master/hardware/Electronics/Schematics) **TODO fix this**. Use the schematics to match the reference designators on the PCBs to the reference designators on the schematics, and then get to soldering.

If you've never soldered surface mount components before, or want a refresher on how to solder, we recommend [this video on using an iron to solder surface mount components](https://www.youtube.com/watch?v=3NN7UGWYmBY), and [this video on using a hot-air soldering station](https://www.youtube.com/watch?v=c_Qt5CtUlqY).
