1). It is a good idea to fill in unused areas of the signal planes with solid copper

2). The signal ground region should be one continuous, unbroken plane extending from the

transformer through the rest of the board.

3). On right angle is recommend when partition the Vcc and GND plane.

4). For EMI consideration, please add 0.1uF caps between system GND and chassis GND.

5). Void the power and ground plane directly under the transformer.

6). The isolation voltage of the transformer should be rated to be greater than 2kv.

7). The sample board Vcc and GND plane at below side.
