Effect of die shape on die tilt in die attach process

Abstract: Die attach process is widely used to realize the connection between die, device and the rest of the system in electronic packaging. During this process, the die moves under the capillary force induced by the liquidus solder. Such a die tilt phenomenon usually occurs and strongly worsens the reliability and performances of devices. In this paper, we built a numerical model based on fluid minimal free energy theory for analyzing the die arrangement in die attach process. By this model, die arrangements of three … Show more

“…Literature suggests eliminating scrubbing in favor of uniform force--also in the presence of inert or reducing atmospheres [7]. Die tilt has been evaluated for die attach with soft solders [8], and modeled for soldering various die shapes [9] which bears on the current work.…”
