Disable the output of the PPG 1. Disable the output of the PPG 2. Set VD = 0V, VCTRL = 0V & VG = 0V 2. Set VCTRL = 0V 3. Set VG = -1.5V 3. Set VD = 0V 4. Increase VD to 8V observing Id - Assure ID = 0mA 4. Set VG = 0V 5. Set VCTRL = +1V - ID should still be 0mA 6. Make VG more positive until ID = 310mA. VG will be approximately -0.3V. 7. Enable the output of the PPG. 8. Output Swing Adjust: Adjust VCTRL slightly positive to increase output swing or adjust VCTRL slightly negative to decrease the output swing. 9. Crossover Adjust: Adjust VG slightly positive to push the crossover down or adjust VG slightly negative to push the crossover up.

Clean the motherboard with Acetone and rinse with alcohol and DI water. Allow the motherboard to fully dry. 2. Using a standard SN63 or lead-free solder paste, dispense solder paste dots of 5 to 15 mil in diameter to the motherboard. Assure that there is a minimum of 5 mils and a maximum of 10 mils between the edge of each solder paste area and the closest edge of the ground pad. 3. Manually place a TGA4819-SL on the motherboard with correct orientation and good alignment. The alignment can be determined manually by centering the package on the motherboard. The RF traces (pin 1 and pin 10) are located along the center horizontal axis of the package. 4. Reflow the assembly on a hot plate with the surface temperature of the plate near 230 oC for 5 to 6 seconds (for SnPb). 5. Let the assembly completely cool down. This package has little or no tendency to self- align during the reflow. 6. Clean the assembly with acetone and rinse with alcohol and DI water.
