Advanced Probing Materials for Semiconductor Testing

ISES Docs:

Testing of high-performance computer chips demands specialized probe needle material solutions, capable of handling high current densities, thermal management challenges as well as mechanical property requirements. To tackle these challenges Heraeus Precious Metals developed a new alloy class – Palysium C+ – utilizing optimized order disorder transitions in Pd-Cu based alloys to form so called superlattice structures. Palysium C+ features exceptional conductivity, while maintaining very good mechanical properties which, in turn, results in a significant increase in the CCC-value compared to state-of-the-art Pd-Cu based solutions, making Palysium C+ the ideal material solution for advanced testing applications.
