Investigation Of Intermetallic Compounds In Sn-Cu-Ni Lead-Free Solders

open access: yesArchives of Metallurgy and Materials, 2015
Interfacial intermetallic compounds (IMC) play an important role in Sn-Cu lead-free soldering. The size and morphology of the intermetallic compounds formed between the lead-free solder and the Cu substrate have a significant effect on the mechanical ...

Wetting and the reaction of multiwalled carbon nanotube-reinforced composite solder with a copper substrate

open access: yesScience and Engineering of Composite Materials, 2013
In this work, contact angle, spreading area, and isothermal aging tests were conducted to study the difference between Sn-3Ag-0.5Cu lead-free solder and its composite solder at different multiwalled carbon nanotube reinforcement volume fractions.

Creep-fatigue life evaluation of Sn-3.5Ag lead-free solder at low temperatures

open access: yesMechanical Engineering Journal, 2016
This paper describes creep-fatigue lives of Sn-3.5Ag lead-free solder at low temperatures. Since solders have lower melting temperature and electronic devices are often used at low temperature environment, it is effective for improving the fatigue life ...

Segmentation of Images of Lead Free Solder [PDF]

open access: yes, 2010
We present two approaches to segment metallic phases in images of lead free solder joints. We compare the results of a method without user interaction with another one extrapolating information from a relatively small set of user labeled pixels. The segmented images provide statistical data of spatial characteristics of phases to serve as input in ...

Size-dependent thermodynamic description of the binary Pb-Sn system [PDF]

open access: yesJournal of Mining and Metallurgy. Section B: Metallurgy, 2017
Recently, a new thermodynamic description of the binary Pb - Sn system was proposed and it seems to be interesting to extend this description on the system, where size of particles plays a key-role.
