– Power trace width > 40 mils (if power trace route to the other side, it must use several via to connect each
– Power source use bulk capacitors (22~47 µf) to reduce noise.
– Provide sample power and ground planes
GND plane
– It is a good idea to fill in unused areas of the signal planes with solid copper.
– The signal ground region should be one continuous, unbroken plane extending from the transformer through
– On right angle is recommend when partition the
– For EMI consideration, please add 0.1 µF caps between system GND and chassis GND.
– Void the power and ground plane directly under the transformer.
– The isolation voltage of the transformer should be rated to be greater than 2 kV.
