• Next, rub the soldering iron tip along the edge of the shield to smooth out any excess sol-
der. Use solder wick and a soldering iron to remove excess solder from the solder pads on
the circuit board.
• Place the circuit board back in the R1070’s circuit board holder.
• Place the shield on the circuit board using a pair of tweezers.
• Position the heat-focus head over the shield and lower it to approximately 1/8” (0.3 cm)
above the shield.
• Turn on the heater and wait for the solder to reflow.
• Once complete, turn off the heat, raise the heat-focus head and wait approximately one
minute for the part to cool.
• Remove the circuit board and inspect the repair. No cleaning should be necessary.
