Despite what you might imagine, people are still very much a necessary part of manufacturing
motherboards, and not just for testing and Quality Assurance either. The
next step in bringing these bare PCB motherboards to life involves a manual assembly line where
all the components that need to be plugged into the pre-drilled holes in
the board are added.
Every plug and I/O interface is added
at this point, from the PCI slots to the CPU socket to the back panel connectors.
As well as slots and sockets, capacitors also require anchoring at
the bottom of the board, so they are added during this step too. These parts
are not soldered to the board during this step, but are simply plugged
in, in assembly line fashion.
