standard solder or solder that contains lead.
We will use PbF when discussing the lead free solder used in our manufacturing process which 
is made from Tin, (Sn), Silver, (Ag), and Copper, (Cu).
This model, and others like it, manufactured using lead free solder will have PbF stamped on 
the PCB. For service and repair work we suggest using the same type of solder although, with 
some precautions, standard Pb solder can also be used.

Caution

- PbF solder has a melting point that is 50° ~ 70° F, (30° ~ 40°C) 

higher than Pb solder. 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.

- PbF solder will tend to splash if it is heated much higher than its 

melting point, approximately 1100°F, (600°C).

- If you must use Pb solder on a PCB manufactured using PbF 

solder, remove as much of the original PbF solder as possible and 
be sure that any remaining is melted prior to applying the Pb 
solder.

- When applying PbF solder to double layered boards, please check 

the component side for excess which may flow onto the opposite 
side (See figure, below).

1.1. SUGGESTED PbF SOLDER

There are several types of PbF solder available commercially. While this product is 
manufactured using Tin, Silver, and Copper,
(Sn+Ag+Cu), you can also use Tin and Copper, (Sn+Cu), or Tin, Zinc, and Bismuth, (Sn+Zn+Bi). 
Please check the manufac
turer’s specific instructions for the melting points of their products and any precautions for 
using their product with other 
materials. 
The following lead free (PbF) solder wire sizes are recommended for service of this product: 
0.3mm, 0.6mm and 1.0mm.
