Impact of Thermal Stress on Glass Substrates

• Thermal Stress Challenges:
  Glass FCBGA substrates are subject to thermal stress due to temperature changes during the soldering process and normal device operation. Thermal stress can lead to several issues such as cracking, delamination, or warping, which are particularly problematic for glass due to its lower thermal conductivity compared to other materials.
  • Mismatch in CTE: The coefficient of thermal expansion (CTE) of glass is different from that of silicon and metals used in the chip assembly, leading to differential expansion and contraction during temperature fluctuations. This mismatch can induce stress at the interface, potentially causing cracks in the substrate or failures at the solder joints.
