Abstract
Una bola de soldadura sin plomo que se instala para su uso como un electrodo en una superficie posterior de un sustrato de módulo para una BGA o un CSP a soldarse a una placa de circuito impresa usando una pasta de soldadura, teniendo la bola de soldadura una composición de soldadura que consiste en un 1,6 - 2,9 % en masa de Ag, un 0,7 - 0,8 % en masa de Cu y un 0,05 - 0,08 % en masa de Ni, opcionalmente al menos uno de los siguientes (i) y (ii) y un remanente de Sn: (i) al menos un elemento seleccionado de Fe, Co y Pt en una cantidad total de un 0,003 - 0,1 % en masa y (ii) al menos un elemento seleccionado de Bi, In, Sb, P y Ge en una cantidad total de un 0,003 - 0,1 % en masa.
Description
Se prepararon aleaciones de soldadura que tienen las composiciones mostradas en la Tabla 1 y es formaron en bolas de soldadura que tenían un diámetro de 0,3 mm mediante el procedimiento de atomización de gas. Las bolas de soldadura resultantes se usaron para evaluar con respecto a los defectos de fusión y mediante un ensayo de fatiga térmica y un ensayo de impacto por caída.
