How Do I solder mPCIe connectors?

Implementing the Mini PCE Express (mPCIe) based mounting system used in BrainBoardz does require access to some tools and supplies that are commonly available to electronics hobbyists:

  • A hot air station
  • A reusable mPCIe stencil (available from JLCPCB and the BrainBoardz store etc. )
  • Lead free SMD solder paste
  • A soldering iron with a fine chisel tip. Hakko T12-D08 tips or similar tips work well for this task.
  • Thin solder wire for the mPCIe re-work on pins and pads. Thicker solder wire can be used for the two larger pads
  • Resin and a solder wick for fixing any soldering issues
  • An analog or digital microscope or a magnifier for verification/rework is strongly recommended

Alternatively, it is also (very!) possible to hand solder mPCIe connectors. For this we recommend:

  • A soldering iron with a fine chisel tip. Hakko T12-D08 tips or similar tips work well for this task.
  • Resin and a solder wick (for fixing any soldering issues)
  • Thin solder wire for the mPCIe pins and pads. Thicker solder wire can be used for the two larger ground pads
  • An analog or digital microscope or a magnifier for verification/rework is strongly recommended

We recommend that you apply liquid resin copiously and use the minimal amount of solder on the pins/pads to limit solder bridging.
