Quality problem handling in lead-free reflow soldering

Definition and classification of welding quality issues: In SMT applications, the quality of the weld of the product can be described by the following definitions. “A certain degree of mechanical and electrical performance can be maintained during the intended use environment, method and lifetime.”

Lead-free wave soldering and rework alloy

Sn96.5Ag3Cu0.5 and Sn95.5Ag4Cu0.5 lead-free alloys are suitable for the replacement of Sn63 alloy. This Sn97Ag3 and Sn96Ag4 variant is used to stabilize/reduce the copper content, which requires the wavesolder bath to depend on the lead-free wave soldering process conditions. With all the alpha metal rod solder, Alpha's proprietary Vaculy? alloying process is used to remove impurities, especially certain oxides.
