(新智造) is a premier digital schematic and bitmap platform used globally by hardware repair technicians, micro-soldiers, and electronics engineers [1]. Primarily targeting smartphones (iPhone, Samsung, Xiaomi), MacBooks, and iPads, this software serves as an interactive blueprint database necessary for modern board-level diagnostics.
Visual 2D representations of physical logic boards. Clicking any pin, trace, or component pad instantly highlights all interconnected nodes across the board. xin zhi zhao schematic

The free account provides only limited functionality. To access full schematics, boardviews, and repair resources, you must purchase a paid activation plan. This is a professional tool with professional pricing.
XinZhiZao—often abbreviated as —is a comprehensive, cloud-based maintenance inquiry database application. It houses a massive, constantly updated library of schematic diagrams, high-resolution bitmaps, board views (Boardview), multi-layer PCB traces, and community-sourced repair cases. : Includes advanced features like infrared thermal imaging
Let’s break down the core features that make XinZhiZao such a powerful tool for repair professionals.

This is where the schematic diverges from common designs. Zhao implements a (based on an SG3525 or TL494 controller) that steps down the rectified 35VDC to a voltage 3V above the desired output. This tracking pre-regulator keeps the linear pass transistor’s dropout low, shifting heat dissipation away from the series pass element.
