XinZhiZao Update — X300 PCB Layer Files Added

XinZhiZao Update for July 4, 2026 adds new X300 PCB layer files for repair technicians who work with board-level diagnostics, connector tracing, PCB layer inspection and motherboard repair references.

This update is focused on X300-related PCB data, including shim boards, connector shim layers, SUB PCB data and MB+SUB references.

The following X300 files were added in this update:

• X300-shim PCB layer.pcb
• X300-ET3212AMA SUB PCB layer.pcb
• X300-ET3212AM MB+SUB YiDianTong.pcb
• X300-Connector shim C PCB layer.pcb
• X300-Connector shim B PCB layer.pcb
• X300-Connector shim A PCB layer.pcb

This update is useful for technicians who need more detailed X300 board references during repair work. PCB layer files can help with connector analysis, sub-board inspection, signal path checking and board structure understanding.

The addition of Connector shim A, B and C references can be especially useful when diagnosing connector-related faults or comparing different board sections during hardware repair.

Technicians using XinZhiZao for board-level repair should update their database and check the new X300 files when working with related repair cases.

As always, exact file usefulness depends on the device, board version and repair situation.

XinZhiZao activation and renewal products are available on S7OFF for professional repair technicians and service shops.
