When it comes
to routing a circuit board a PCB designer has a difficult task. When high speed
PCB routing and signals are involved things get more complicated. In an effort
to help different PCB designers, a list of best high speed PCB routing
practices has been made that will assist them in achieving that perfect
high-speed design.
It was not that
long when the word “high speed” didn’t exist in the vocabulary of PCB designers. However these days, it seems to be just opposite. At that time, the
only concern was all about putting the puzzle pieces together and strategist
your way through a physical board layout. But what with high speed design? Now
here there is a bunch of invisible forces to worry about, things like
electromagnetic interference which is also known as EMI, cross-talk, signal
reflection and etc.
To handle
the extra advanced computing needs of these devices high speed circuitry is
required in dense PCB designs. Other than that is the RF portion of these
devices which increases the complexity of their small yet powerful circuit
boards. However to successfully design these boards, PCB designers need to
balance the requirements of a board that has both high speed and RF PCB routing
on it.
