FLUX COMPOSITION, METHOD FOR FORMING ELECTRIC CONNECTION STRUCTURE, THE ELECTRIC CONNECTION STRUCTURE, AND SEMICONDUCTOR DEVICE

摘要

PURPOSE: a kind of flux composition, electric structure and forming method thereof and semiconductor devices are provided, and to obtain good electric connection structure, pass through reflux from flux and circuit board electrical connection without exposing convex block. ;CONSTITUTION: a kind of solder flux composition includes the equation that aldehyde alcohol (one) and polymer B have opposed configuration unit. In the formula, R1 indicates that hydrogen atom or methyl, Z represent polar hydroxyl groups, and iodine group, carboxyl, formoxyl, amino, nitro, sulfydryl, sulfo group , oxazolinyls, diimide group, amide structure or group have those groups. ;The 2013 of copyright KIPO submissions;[Reference numerals] (AA) reflow temperature (& deg; C ); (BB) time (minute)
