1 ABOUT LEAD FREE
SOLDER (PbF)
Distinction of PbF PCB:
· PCBs (manufactured) using lead free solder will have a
PbF stamp on the PCB.
Caution :
· Pb free solder has a higher melting point than standard
solder; Typically the melting point is 50 - 70°F (30 40°C) higher. Please use a soldering iron with
temperature control and adjust it to 700 ± 20°F (370 ±
10°C). In case of using high temperature soldering iron,
please be careful not to heat too long.
· Pb free solder will tend to splash when heated too high
(about 1100°F/600°C).
2 FEATURES
· PLL (Phase Locked Loop) synthesized tuning
· MP3/WMA playback from CD-R/RW
· ALPS Tuner Pack (Digital Tuner)
· Illumination Color-Amber
