XinZhiZao — Professional Schematic & Board View Software

6 min read

What is XinZhiZao?

XinZhiZao is a professional schematic, board view, and repair resource software platform originating from China. It provides detailed electronic circuit diagrams, PCB board views, component databases, and repair guides for mobile phones, tablets, laptops, drones, gaming consoles, and other electronic devices. XinZhiZao is widely used by hardware repair technicians in Asia and increasingly worldwide.

Core Features — Technical Detail

Feature	How It Works
Schematic Diagrams	Full electronic circuit schematics organized by functional block: Power Management (PMIC/regulators/DC-DC converters), Application Processor, Baseband/Modem, Display & Touch, Audio, Camera, WiFi/BT/GPS, NFC, Charging (USB-C PD, wireless Qi), SIM interface, memory (RAM/storage). Multi-page format with cross-references between pages
Board View (PCB)	Interactive top-side and bottom-side PCB layouts. Click any component to see: part number, pin connections, connected nets, component value (resistance/capacitance/inductance). Support for BGA pad-level view (essential for reballing and micro-soldering). Toggle individual PCB layers (copper, solder mask, silkscreen)
Signal Tracing	Click any net or pin to highlight the entire signal path from source to destination across both PCB and schematic views simultaneously. Example: click VBAT on battery connector, see the entire power distribution from battery through PMIC outputs to every IC power pin
Component Database	Cross-reference database for ICs and components: lookup a part number to find compatible replacements, pin assignments, recommended operating conditions, and which device models use that component
Bitmap/Photo View	High-resolution photographs of actual PCBs — useful for visual inspection, component marking identification, and comparing physical board against schematic diagram
Repair Case Library	Real repair case reports from other technicians: symptom description, diagnosis process, identified fault, and solution. Searchable by device model and symptom (no power, no charge, no network, etc.)

Device Categories — Beyond Phones

Unlike phone-only schematic tools, XinZhiZao covers multiple device categories:

Mobile Phones

Apple iPhone: iPhone 15 Pro Max through iPhone 6 — full schematics + board view + bitmap for every model
Samsung: Galaxy S/A/M/Note/Z series — Exynos and Qualcomm variants
Xiaomi/Redmi/POCO, Huawei/Honor, Oppo/Realme/OnePlus, Vivo
Chinese brands: Extensive coverage of Chinese market devices (Transsion brands, Meizu, etc.)

Tablets

Apple iPad: iPad Pro, iPad Air, iPad Mini, standard iPad — all generations
Samsung Galaxy Tab, Xiaomi Pad, Huawei MatePad

Laptops

Apple MacBook: MacBook Pro, MacBook Air — Intel and Apple Silicon (M1/M2/M3) boards
Competitors: Some coverage for HP, Dell, Lenovo, ASUS motherboard schematics

Drones

DJI: Mavic, Mini, Air, Phantom series — flight controller boards, gimbal boards, ESC boards
Board-level repair for drone motor drivers, GPS modules, camera stabilization circuits

Gaming Consoles

PlayStation: PS5, PS4, PS4 Pro/Slim — power supply, APU/GPU area, HDMI, BD drive
Xbox: Xbox Series X/S, Xbox One — similar board-level coverage
Nintendo Switch: Main board, charge IC, USB-C port area

Subscription Model

XinZhiZao uses a time-based subscription with unlimited access to all schematics and board views in the database during the subscription period. No per-device or per-schematic charges.

How to Use XinZhiZao: Step-by-Step

Purchase a subscription from Code-GSM
Download and install XinZhiZao software
Log in
Search for your device model
Open Board View: Physical PCB layout showing component locations
Open Schematic: Full circuit diagram with labelled nets and component values
Click any component to see its specifications, part number, and connected signals
Use signal tracing to follow connections across the board

Tips

XinZhiZao has excellent coverage of Chinese-market phones (Xiaomi, OPPO, Vivo, Huawei) in addition to Apple and Samsung
Board View is essential for locating components physically when repairing — cross-reference with the schematic
Use the component search to quickly find ICs by name (e.g., "PM8350" for the power management IC)

Common Repair Workflows with XinZhiZao

Repair Type	XinZhiZao Workflow
Find a failed capacitor	1. Open Board View for device → zoom to the area of suspected fault. 2. Click the capacitor pad → see cap value (e.g. 100nF, 1µF) and the net it sits on. 3. Open Schematic and search the net name → trace the power rail to the source PMIC. 4. Identify if the cap is a decoupling cap (filter) or part of a charge pump. 5. Order exact replacement by BOM part number shown in XinZhiZao
Diagnose a Chinese phone (no service)	Search by the Chinese model name or use global alias (e.g. Redmi Note 12 / Xiaomi 22111317I). Open RF section schematic. Check antenna switch paths, PA module pinout, and LNA connections. Many Chinese phones use shared TAS/QM parts — schematic shows exact connections
Laptop motherboard water damage	Open laptop model in Schematic view → look at power delivery section. Trace VCC rails from DC-IN through power sequencing ICs. CPC pinout, MOSFET gate drives, and voltage rail names help identify which rail was shorted
Drone repair (DJI):	Open DJI Mavic/Mini model. Board View shows flight controller, ESC, gimbal driver placement. Schematic shows motor driver IC pins, PWM signals, battery connector rails for quick voltage testing

Troubleshooting XinZhiZao

Problem	Solution
Device model not found in the database	Try different spelling or the regional name. XinZhiZao uses Chinese model designations — try the device's full model number (e.g. "CPH2269" for OPPO A96). Check for recent software update that may have added new models
Schematic shows in Chinese only	XinZhiZao originated in China but most component designators (R, C, U, L) and net names are universal. Component values (resistance, capacitance) are standardized. The functional block descriptions may be in Chinese — use a browser translation extension for reference
Board View and Schematic components don't match	Ensure you are on the same hardware revision. Some phones have PCB revisions (Rev 1.0, Rev 2.0) with different layouts. Check if XinZhiZao has multiple board versions for your model
Software won't start / license error	Ensure you are logged in with valid credentials. Check internet connectivity — subscription validation requires server contact. Try reinstalling the software

Frequently Asked Questions

Q: Does XinZhiZao include Samsung Galaxy schematics?
A: Yes — Samsung Galaxy S and A series are well covered. XinZhiZao is particularly strong for Chinese Android brands (Xiaomi, OPPO, Vivo, Huawei) and has growing Apple and Samsung coverage.

Q: Can I use XinZhiZao for laptop repair only?
A: Yes — XinZhiZao covers a wide range of laptops (Apple MacBook, selected HP/Dell/Lenovo), PC motherboards, and even gaming consoles and drones. It's a full electronics repair reference platform.

Q: Is the XinZhiZao database constantly updated?
A: Yes — new device schematics are added regularly. Subscribe to the XinZhiZao update notifications or check the software for the latest additions.
