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 the 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.
