: Displays ground values for pins directly on the PCB drawing, helping technicians quickly identify short circuits.
Recent updates to the XinZhiZao software have introduced several advanced features that streamline the troubleshooting process: xin zhi zhao schematic updated
We cleaned up the layout and fixed a few gremlins in the previous version. If you’re working with this board, you’ll want to grab the new files. Let me know if you spot any issues! : Displays ground values for pins directly on

: Schematic and boardviews for motherboards and graphics cards.
: Users can add annotations and "maintenance marks" to PCB drawings, which are stored securely in the cloud and can be shared with other technicians. Advanced Diagnostics : Recent versions include integration with infrared thermal imagers to highlight leakage points on mainboards. Activation & Access
