The whole process of copper wire ball bonding and gold wire ball bonding were compared and analyzed , and a central composite design of experiment ( doe ) approach was applied to optimize the parameters of free air ball formation process and bonding process , separately 本文首先對(duì)比分析了銅絲球鍵合和金絲球鍵合的全過(guò)程,采用實(shí)驗(yàn)設(shè)計(jì)分別對(duì)燒球工藝參數(shù)和鍵合工藝參數(shù)進(jìn)行了優(yōu)化。在此優(yōu)化參數(shù)下,獲得了連接良好的銅絲球鍵合點(diǎn)和金絲球鍵合點(diǎn)。
