EMC Issue in Cloning Printed Wiring Board

When Cloning Printed wiring board, engineer should be aware of the electronic magnetic compatibility issue. Electronic magnetic compatibility means the electronic device can work properly, efficiently and coordinately in the environment of various electronic and magnetic.

The purpose of design electronic magnetic compatibility when cloning Printed wiring board is to make the electronic device can not only resist the interference from outside world, but also can decrease the electronic magnetic inference from itself to other electronic device.

Use the correct strategy of Printed wiring board cloning process, use parallel track layout can decrease the conductance of wire, but the conductance value among wires and distributed capacitors, if the Printed wiring board layout is allowable, it is better use pump shape net to construct the structure when cloning Printed wiring board, and the instruction method is make it vertical layout from one side, and the other side layout by integral orientation, and use metallic hole on the crossing point. In order to depress the cross talk among wires on the Printed wiring board after cloning, parallel layout with long length on the Printed wiring board when layout should be avoided as much as possible.
