Excessive heat instantly delaminates the organic CPU substrate. Please note that this is not an exhaustive
The System-on-Chip (SoC) voltage rail powers the non-core components of the processor, collectively known as the "uncore."
Why does an exclusive breakdown matter?
If the pin snaps, the CPU can sometimes still function depending on the pin's purpose. If it’s a Ground ( VSScap V sub cap S cap S end-sub ): The CPU might work fine. If it’s Memory ( VDDIOcap V sub cap D cap D cap I cap O end-sub ): One or more RAM channels might fail.
