The components on the Snapdragon 665 platform are tightly packed. Use a high-quality microscope and fine-tipped soldering iron hooks ( ) when running jumpers.
SMB1351 or similar Qualcomm charging IC Network/RF IC: Qualcomm SDR660 Transceiver Key Sections of the Vivo U10 Schematic Diagram
If the phone boots (vibrates or plays sound) but the screen remains black, you face a display or backlight circuit failure:
Unlike flagship phones, the Vivo U10 lacks official service manual leaks from Vivo. Most free PDFs are:
The Vivo U10 (model 1907) is a popular budget smartphone powered by the Snapdragon 665 chipset. Despite its affordability, its PCB (Printed Circuit Board) is densely packed with tiny components. Without a schematic, tracing a dead charging port, a missing audio IC, or a cracked display backlight fuse becomes a nightmare.
For technicians and DIY enthusiasts, obtaining a reliable Go to product viewer dialog for this item.
Always verify voltages with a multimeter first.
To effectively read a Vivo U10 schematic, you must first understand the core hardware architecture of the device. The Vivo U10 is built on a mid-range Qualcomm platform, meaning its power sequences and logic paths follow standard Qualcomm design philosophies. Qualcomm SDM665 Snapdragon 665 (11 nm)
This document uses standard electronic symbols to show how components connect. It details the voltage lines, data lines, and ground connections. For example, it will map out how the battery connector ( JBAT ) connects to the PMIC through various protection resistors and capacitors. 3. The Interactive Bitmap (Recommended)
Provides highly detailed multi-layer motherboard tracing options that make tracking down broken lines inside the Vivo U10 PCB remarkably straightforward.
