Retention Force
The length of the pins on the expansion header has a direct relationship to the amount of
force that is used to remove a cape from the BeagleBone Black. The longer the pins
extend into the connector the harder it is to remove. There is no rule that says that if
longer pins are used, that the connector pins have to extend all the way into the mating
connector on the BeagleBone Black, but this is controlled by the user and therefore is
hard to control.
This section will attempt to describe the tradeoffs and things to consider when selecting a
connector and its pin length.

Figure 62
shows the key measurements used in calculating how much the pin extends
past the contact point on the connector, what we call overhang.
