A method and apparatus for establishing a connection, wherein a response to a call setup request of a first type of connection is checked by a signaling control unit and a signaling of a second type of connection received from the other party of the connection is monitored. An impedance matching control module generates a control signal, based on the one or more secondary signals, which is indicative of an impedance mismatch between a load and a communications device. A copper heat spreader is formed in the redistribution layer over the die in a same layer as a plurality of electrical traces configured to couple circuit pads of the semiconductor die to respective contact lands of the land grid array. A crop location can then be selected based upon the candidate cropped image having the largest output.
