8.1 Building the STEM Payload Board

These are the instructions for building the STEM Payload board.

Pico PCB

You will need these tools:

  • Safety glasses (to protect eyes while soldering or trimming leads)
  • Soldering iron with fine tip and very thin solder (I use lead-free solder, but leaded solder is easier to work with)
  • Flux pen
  • Tweezers
  • Needle nose pliers (to bend leads and hold parts)
  • Side cutters (to trim leads)

Other tools that are helpful:

  • Blue mounting putty (to hold components in place while soldering)

Checklist

The BOM has a sheet "By Steps" which lists the parts needed for each step in order. http://cubesatsim.org/bom If you have a Google account, you can make a copy of this spreadsheet ("File" then "Make a Copy") and check off each part as you install it.

For example, here is the checklist for this step:

Assembly

Video

Here is a video of the assembly part of this step:

Here is the Pico v0.2 PCB:

First solder the surface mount parts which includes the SAW Filter and the SR_FRS board.
