Effect of the Er on resistivity and spreading properties of Bi5Sb8Sn solder alloy Shuai Li 1,a, YanFu Yan 1, b, LiFang Feng 1,c, HongNa Wang 1,d 1College of Material Science and Engineering, He Nan University of Science and Technology, Luoyang,China 471003 aemail: lyctlishuai@163.com ,bemail: yanyanfu@mail.haust.edu.cn, cemail: fenglifang198306@126.com, demail: xiaona1986107@126.com Keywords: quaternary alloy;rare earth Er; resistivity;spreading area Abstract: In this paper a novel quaternary alloy is formed by adding a small amount of rare earth Er(RE) into Bi5Sb8Sn solder alloy to improve its technological properties.
In this paper, a new Bi5Sb8SnRE quaternary alloy was formed by adding different contents of Er which could alternate high-lead solders and the high-cost Au-based solders to speed up China’s lead-free process. 2 Experiment procedure 2.1 Solder preparation The pure Bi, Sb, Sn and Er with purity of 99.95% were used as raw materials.

Up to now, many materials have been reported to have the resistive switching (RS) properties, such as transition metal oxides, chalcogenide materials, polymer and organic materials, amorphous Si, and graphene derivates [3].
Therein, BiFeO3 (BFO) become one of the most important materials for RS effect due to its tunability of leakage current, which broaden its potential use in novel, multifunctional device applications [5].
