METHOD OF CONNECTING A SEMICONDUCTOR PACKAGE TO A PRINTED WIRING BOARD

摘要

A method of electrically connecting a bump array package to a wiring board, comprising the steps of: arranging a thermofluidizing, thermosetting adhesive film on a surface of a bump array package having metal bumps; creating a bump array package having a flat surface comprising said metal bumps and said adhesive film, and connecting the bump array package to the wiring board by arranging the flat surface comprising said metal bumps and said adhesive film on the wiring board, and heating the adhesive film at a temperature high enough for finishing the setting of said adhesive film and higher than the melting temperature of said solder.
