About Lead Free Solder (Pbf) - Panasonic CT-27SL15 Service Manual

Note: Lead is listed as (Pb) in the periodic table of elements.
In the information below, Pb will refer to Lead solder, and PbF will refer to Lead Free Solder.
The Lead Free Solder used in our manufacturing process and discussed below is Sn(Tin)+Ag(Silver)
+ Cu(Copper).
This model uses Pb Free solder in it's manufacture due to environmental conservation issues.
PCBs manufactured using lead free solder will have the PbF within a leaf Symbol
front of PCB.
Caution
• Pb free solder has a higher melting point than standard solder. Typically the melting
point is 30 ~ 40 °C higher. Please use a high temperature soldering iron
and set it to 350 ± 5°C.
• Pb free solder will tend to splash when heated too high (about 1100 °F or 600 °C).
If you must use Pb solder, please completely remove all of the Pb free solder on the
pins or solder area before applying Pb solder. If this is not practical, be sure to heat the
Pb free solder until it melts, before applying Pb solder.
• After applying PbF solder to double layered boards, please check the component side
for excess solder which may flow onto the opposite side. (see figure below)
Suggested Pb free solder
There are several kinds of Pb free solder available for purchase. Although, this product can be
used only Sn+Ag+Cu(tin, silver, copper) solder
