Characteristics of SI10U
SI10U is characterized by its low coefficient of thermal expansion (CTE) and high modulus, which can effectively reduce the warpage of packaging substrates. It also boasts excellent heat and humidity resistance, good PCB processability, and is made from halogen-free materials.
Application Areas for SI10U
The application areas for SI10U include eMMC, DRAM, AP, PA, Dual CM, Fingerprint, and RF Module.
