Printed circuit boards and breadboard devices have contact pads and
magnetic component connectors where connection between the contact pads
and the magnetic component connectors are made by magnetic force. Either
the contact pad or the magnetic component connector will be magnetic and
the other will be made of a material to which a magnet will be attracted.
For example, printed circuit boards, which usually have copper traces,
include contact pads made of a material to which a magnet will be
attracted. Circuit components are connected to magnetic component
connectors having magnetic legs which then connect the components to the
contact pads of the circuit board or breadboard device. This makes the
connection of components to a printed circuit board or breadboard device
fast and easy and provides for easy removal and replacement of
components. Magnetic component connectors can also be configured to
connect magnetically to one another.
