If a copper trace inside the multilayer PCB breaks due to a drop, a patched schematic provides a workaround solution. For example, if the power button track is broken, the patched diagram highlights an alternative test point (TP) or component pin where a fine copper enamel wire can be soldered directly to restore the signal path to the PMIC. 4.
