8-4 Maintenance: Recommended Test Tools
To replace the shield:
1. Add solder to the shield if necessary, using a micro-tipped soldering iron.
2. Next, rub the soldering iron tip along the edge of the shield to smooth out any excess solder.
Use solder wick and a soldering iron to remove excess solder from the solder pads on the
circuit board.
3. Place the circuit board back in the R1070’s circuit board holder.
4. Place the shield on the circuit board using a pair of tweezers.
5. Position the heat-focus head over the shield and lower it to approximately 1/8” (0.3 cm) above
the shield.
6. Turn on the heater and wait for the solder to reflow.
7. Once complete, turn off the heat, raise the heat-focus head and wait approximately one
minute for the part to cool.
8. Remove the circuit board and inspect the repair. No cleaning should be necessary.
