Patent ID: 7193244

Claim:
An electronic device comprising: a substrate having a primary surface; an array lying along the primary surface, wherein the array includes one or more radiation-emitting components, one or more radiation-responsive components, or any combination thereof; and a first edge connector, wherein, in a direction parallel to the primary surface, the first edge connector lies between the array and a perimeter of the substrate, wherein: the first edge connector is connected to the array and designed to transmit a power signal into the array; the electronic device is designed, such that during normal operation, the first edge connector has a temperature difference, due to current flow through the first edge connector, of no more than 10° C.; the temperature difference is a first temperature minus a second temperature; the first temperature is a temperature of the first edge connector when the first edge connector is at a substantially steady state temperature; and the second temperature is a substantially ambient temperature.
