The Apple A15 and A16 Bionic chips utilize a highly complex, hardware-bound ecosystem where the CPU, NAND flash, Secure Enclave, and the specific wireless logic chip are cryptographically married. If an iPhone 13 or 14 experiences severe physical or water destruction, a standard component transplant is incredibly difficult because the wireless baseband and pairing keys are deeply integrated into the security handshake.
To extract court-admissible evidence from a dead A15 or A16 device, cleanroom engineers rely heavily on diagnostic thermal imaging cameras. Instead of guessing where a short circuit is located beneath the solid metal shielding cages, technicians power the board via a controlled DC power supply. The thermal camera instantly captures the exact micro-capacitor that is shorting out, allowing the engineer to perform a precision micro-abrasive excision of just that single component, reviving the native logic board without risking a catastrophic chip transplant.
