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 Web18 de nov. de 2024 · Laser-assisted bonding shines a laser beam to the chips, where the bump tips are Sn or SnAg. LAB is used to connect them to the substrate. This gives a higher UPH (units per hour) and more robust interconnection than thermocompression. It provides much less residual stress than MR (mass reflow).
