80Au/20Sn has a melting point of 280°C (556°F). lt has the characteristics of excellent thermalconductivity and conductivity, high tensile strength, high reliability, good wettability, corrosionresistance and compatibility with other precious metals. it has been widely used in aerospace.military industry, medical treatment, optical communication and other fields.
Au80Sn20 Golden tin ball, because ofits stableperformance, ultra-low air hole bubble rate, simpleprocess control, strong oxidation resistance, highshear and tensile strength, gold tin ball is widelyusedin modern microelectronic packaging fieldssuch as BGA (ball grid array packaging), CSP(chip size packaging). With the miniaturization ofintegration,it has gradually become the mainstreamauxiliary materials for advanced packaging such asFILP chip, WLCSP, MEMS and so on,
Chengdu Apex New Materials Co.,Ltd independently developed and produced gold tin balls with aminimum ball diameter of 50 um.At the same time, we can also provide professional andcustomized services according to customer needs.
