Unauthorized copying and distribution is a violation of law. 1. ABOUT LEAD FREE SOLDER (PbF: Pb free) Note: In the information below, Pb, the symbol for lead in the periodic table of elements, will refer to standard solder or solder that contains lead. We will use PbF solder when discussing the lead free solder used in our manufacturing process which is made from Tin (Sn), Silver (Ag), and Copper (Cu).
Page 3
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.
Page 4
(Component View) (Flow Solder Side View) Note: The location of the “PbF“ mark is subject to change without notice. 2. FOR SERVICE TECHNICIANS ICs and LSIs are vulnerable to static electricity. When repairing, the following precautions will help prevent recurring malfunctions. 1.
