Web30 de jun. de 2024 · DBI Ultra offers bonding throughput comparable to mass reflow flip chip assembly. The bonding takes place at room temperature in an ambient environment in a class 1000 cleanroom. A low temperature batch anneal after bonding results in solid Cu-Cu connection with no solder and no underfill. Webpromising solutions is laser assisted bonding (LAB) technology. The keyadvantage of LAB is its extremely short bonding time (less than 1 sec) with a localized heating area which provides low thermal and mechanical stresses. In this study, two bonding profiles of “time fixed”and “power fixed”are tested using 15.2 x 15-mm2 FCBGA test vehicles
