WebSep 23, 2024 · PCB Tg Coefficient Of Thermal Expansion(CTE) The coefficient of thermal expansion depends on the composition of the components of the base material and their … WebPCB flatness is a critical requirement, especially for boards using surface mount devices. Ball grid arrays are particularly sensitive to PCB flatness as the pin-count rises. Once a board has turned itself into a “potato chip”, it can be flattened under heat and pressure, but the underlying reason why it was in the twisted state remains.
