(3) Reworking with Solder Iron
The following conditions must be strictly followed when
using a soldering iron.(Except BLM02 Series)
Pre-heating: 150°C 60s min.
Soldering iron power output / Tip diameter:
80W max. / ø3mm max.
Temperature of soldering iron tip / Soldering time / Times:
350°C max. / 3-4s / 2 times
Do not allow the tip of the soldering iron to directly
contact the chip.
For additional methods of reworking with a soldering iron,
please contact Murata engineering.
