In this study, the novel ACA’s performance under highly accelerated stress testing (HAST), temperature humidity, and thermal aging will be discussed in detail. The test data will show that by modifying the ACA filler particle size and filler particle coating, the reliability performance under temperature-humidity aging can be positively impacted. In addition, the data will also show that thermal aging actually improves the contact resistance performance. Furthermore, the contact resistance performance of the different adhesive formulations will also be corroborated with shear testing.
