After the solder paste has been added, electronic components are placed on the board using surface mount technology machines.
These machines can mount close to 25,000 components every hour, placing individual components in a blur of motion.
Each Pi has 173 surface mounted components, and it typically takes 150 seconds to finish mounting the six boards in a panel.
The factory uses three such machines to produce the Pi, one for mounting the underside of boards and two for the top.
