If neighboring PBGA components are heated above 365 degrees F. (185 degrees C.), they will suffer die-bond delamination and possible “popcorn” failure. To prevent this delamination problem, circuit boards to be repaired must be baked in an oven for eight hours at 260 degrees F. (125 degrees C.) prior to solder repairs.

All pad-array carriers in these radios, except for

!the IF IC (U3), are PBGA components. Prior to use, all PBGA components must be kept in the sealed

bag (with moisture-indicator card) as supplied by the Motorola Parts Department. Once the sealed bag is opened and/or the PBGA component subjected to ambient humidity (for an unknown amount of time or for more than 96 hours) then that PBGA component must be baked in an oven for at least eight hours at 260 degrees F. (125 degrees C.)

During all repair procedures, heating neighboring components can be minimized by:

•using upper heat only.

•using the correct size heat-focus head, approximately the same size as the carrier being replaced.

•keeping the heat focus head approximately 1/8”-1/4” (0.3cm- 0.6cm) above the printed circuit board when removing or replacing the device.

To Remove a PBGA Component, select the R-1319 Rework Station and the appropriate heat- focus head (approximately the same size as the PBGA. Attach the heat-focus head to the chimney heater. Adjust the temperature control to approximately 415 degrees F (215 degrees C); 445 degrees F (230 degrees C) maximum. Apply the solder paste flux around the edge of the PBGA. Place the circuit board in the circuit board holder, and position the PBGA component under the heat-focus head. Lower the vacuum tip and attach it to the PBGA component by turning on the vacuum pump. Lower the heat-focus head until it is approximately 1/ 8”-1/4” (0.3cm-0.6cm) above the carrier. Turn on the heater and wait until the PBGA component lifts off the circuit board. Once the part is off, grab it with a pair of tweezers and turn off the vacuum pump. Remove the circuit board from the R-1319’s circuit board holder.
