  • Page 2: About Lead Free Solder (Pbf: Pb Free)

    IMPORTANT INFORMATION ABOUT LEAD FREE, (PbF), SOLDERING If lead free solder was used in the manufacture of this product the printed circuit boards will be marked PbF. Standard leaded, (Pb), solder can be used as usual on boards without the PbF mark. When this mark does appear please read and follow the special instructions described in this manual on the use of PbF and how it might be permissible to use Pb solder during service and repair work.

  • Page 3: For Service Technicians

    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.
