Properties of Sn0.7Cu Solder Alloys Bearing Fe and Bion behavior of Sn–0.7Cu (SC07) lead-free solder alloy are presented. The addition of Fe and Bi to the SC07 alloy leads to significant changes in the microstructure and chemical state of tin. The minor addition of Fe to binary SC07 alloys leads to the formation of an intermetallic FeSn. compound with

The Effect of Isothermal Ageing Treatment on Different PCB Surface Finishes: Simulation and Experime. The surface finishes selected in this study are electroless nickel immersion gold (ENIG) and hot air solder levelling (HASL). The Pb-free solder ball used is SAC-x Ni (x = 0.5 wt.% and x = 1.0 wt.%) with a diameter of 500 µm. All the samples were subjected to the isothermal ageing process. The int

Advancement of Printed Circuit Board (PCB) Surface Finishes in Controlling the Intermetallic Compounnnections for the circuit’s functionality. Various types of surface finishes are often applied onto the Cu pad of the PCB to protect the Cu pad prior to the soldering process. Furthermore, the application of surface finishes is to ensure good solderability. An intermetallic compound (IMC) layer form

Significance of Intermetallic Compound (IMC) Layer to the Reliability of a Solder Joint, Methods of nducted whereby the excessive growth of IMC could lead to solder joint failure. Thus, many attempts have been made to determine the actual IMC thickness. Average values of IMC thickness are always used to represent the IMC layer. However, precise, and true representation of the IMC layer growth in t
