EK13 Evaluation Kit APPLICABLE PARTS (SOLD SEPARATELY) • • PA341DF PA441DF INTRODUCTION Fast and easy breadboarding of circuits using the PA341DF/PA441DF is possible with the EK13 evaluation kit. The amplifier may be surface mounted directly to the PC board. The PA341DF/PA441DF is soldered to a 2square 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.

Solder paste may be dispensed or screen-printed on the DUT pads. The heat tab on the back of the PA341DF/PA441DF 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 PA341DF/PA441DF 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. CAUTION High Voltages will be present. Use caution in handling and probing when power is applied. NEED TECHNICAL HELP? CONTACT APEX SUPPORT!
