Copper cooling plate, heat sink for Tibbo EM203A+RJ203A converters

Kurzbeschreibung

The EM203 module features a heat-conductive sticker. Protective paper of the sticker MUST BE REMOVED prior to installing the module onto the host PCB. More on this in the Thermal Considerations topic.
The DM9000B Ethernet controller of the EM203 can become very hot during normal module operation. To aid the module in dissipating excess heat, a special heat-conductive sticker is applied to the top of the DM9000B. Protective paper of the sticker MUST BE REMOVED prior to installing the module on the host PCB.

To further lower the operating temperature of the EM203 we advise you to arrange a copper area on the host PCB and in contact with the heat-conductive sticker. Best results are achieved when the copper area is larger, and also when two copper areas are provided on both sides of the host PCB and interconnected by a number of large vias.
