�������������������������� ���� � � � � � � � � � � � � � � � �������������������������������������������������������������� INTRODUCTION ASSEMBLY Fast and easy breadboarding of circuits using the PA241DF IS possible with the EK13 evaluation kit. The ampliﬁer may be surface mounted directly to the PC board. The PA241DF is soldered to a 2-square inch area of foil on the PC board for heat sinking. This foil heat sink is connected to–Vs. Connections are provided for required power supply bypassing, phase compensation components, and a current limit resistor. A large area for component mounting provides ﬂexibility and makes a multitude of circuit conﬁgurations possible. The PA241DF is a surface mount device and should be assembled to the EVAL15 PC board using surface mount processes. Solder paste may be dispensed or screen-printed on the DUT pads. The heat tab on the back of the PA241DF provides maximum heat dissipation capabilities when soldered to the PCB metalization that runs under the DUT on the DUT side of the board. Solder should be applied here also. For prototype purposes, the tab can be thermally connected to the PCB metalization using thermal grease. The PA241DF and HS24 should be reﬂowed to the PCB using a solder reﬂow furnace. If this is not available, a heat plate capable of solder reﬂow temperatures may be used. or, though time consuming, the leads may be soldered individually to the PCB with a soldering iron. In this case the use of thermal grease under the heat tab is recommended instead of solder for the thermal connection.
