Preparing the die: The first step in the flip chip assembly process is preparing the die. This involves testing the die for any defects or flaws before assembly begins. It also involves cleaning the die, and removing any impurities that could interfere with the assembly process.
Websubstrate, we used a flip-chip bonding process. The process was similar to that of Singh, et al., which used flip-chip compression bonding to transfer released MEMS devices to a secondary substrate [1]. The process described in this paper, however, transferred unreleased MEMS to a secondary substrate using flip-chip thermosonic bonding. Webbeing designed using the HR QFN package technology, which eliminates bond-wires and minimizes the parasitic resistance and inductance. This is done by flipping the die and …
