Abstract:
A printed circuit board for attaching electronic components, the printed circuit board comprising:a power plane that is subdivided into a plurality of power islands;a ground plane;a plurality of bypass capacitors, each bypass capacitor being connected between the ground plane and an associated one of the power islands;a connector mounted on the printed circuit board for receiving electrical components, wherein the connector is connected to at least two selected power islands and the ground plane, wherein the selected power islands are arranged such that when a first electrical component is inserted into the connector, a first one of the selected power islands is automatically connected to a power supply pin of the first electrical component to facilitate attenuation of electromagnetic interference generated by the first electrical component in a first frequency band, and when a second electrical component is inserted into the connector, a second one of the selected power islands is automatically connected to a power supply pin of the second electrical component to facilitate attenuation of electromagnetic interference generated by the second electrical component in a second frequency band that is different then the first frequency band.
