Printed circuit board with right-angled trace and method for making the same

摘要

A printed circuit board having right-angled trace and a method for making the right-angled trace is to apply semi-conductor material and form an interface with a P-type semi-conductive layer and a N-type semi-conductive layer. The semi-conductive right-angled interface does not reflect signals transmitting from the first line portion to the second line portion and via the right-angled portion so as to reduce signal reflection interference. The right-angled line arrangement also shortens the connection distance and reduces the circuit board dimensions.
