5. This Product Uses Lead (Pb) Free Solder Printed Circuit Boards (PCBs).
Information regarding Lead-Free (PbF) solder;
Information regarding Lead-Free (PbF) solder;
Distinction of PbF PCB:
PCBs (manufactured) using lead free solder will have a mark following
the PCB part numbers in a label on the PCB.
the PCB part numbers in a label 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). Exercise care while using higher
temperature soldering irons, do not heat the PCB for too long to prevent solder splash
or damage to the PCB.
control and adjust it to 700 20 F (370 10 C). Exercise care while using higher
temperature soldering irons, do not heat the PCB for too long to prevent solder splash
or damage to the PCB.
Pb free solder will tend to splash when heated too high (about 1100 F/600 C).

with the national laws transposed from the EU Directive on the restriction of the use of
certain hazardous substances (RoHS) in electrical and electronic equipment, effective
July 1, 2006 in the EU countries.
In order for the product to comply with the RoHS Directive, the six particular substances
(lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls, and
polybrominated diphenyl ethers) have been either totally eliminated or limited to the
concentration level below maximum allowed. Consequently spare parts have been
changed to RoHS-compliant parts where applicable.
