Supported Chipset & IC Details

The QU5 is a multi-functional stencil, meaning it contains multiple patterns on a single sheet to cover a specific generation of Qualcomm processors.

1. High-Performance CPUs (Snapdragon 8 Series)

SDM845 (Snapdragon 845): Found in legendary flagships like the Samsung S9, Google Pixel 3, and OnePlus 6. The stencil provides layouts for both the CPU and the matching RAM.
SM8150 (Snapdragon 855): Used in the Samsung S10, OnePlus 7, and Xiaomi Mi 9. It handles the complex ball grid of the 855 architecture.

2. Mid-Range & Efficient CPUs

SDM710 / SM6150: Common in “premium mid-range” devices (e.g., Xiaomi Mi 8 SE, Redmi Note Pro series).
SDM670: Optimized for power efficiency, found in the Pixel 3a.
MSM8917 (Snapdragon 425): Support for entry-level older architectures often used in budget tablets and phones.

Key Features & Professional Benefits

Square Hole Technology

Unlike cheaper stencils that use round holes, Amaoe uses square apertures. This design prevents solder paste from “sticking” to the walls of the stencil. When you lift the stencil after applying paste, the square shape allows for a cleaner release, resulting in uniform, perfectly formed solder balls. Amaoe QU5 BGA Reballing Stencil-Original

Anti-Buckling Design

Micro-soldering requires intense heat from a hot air station. The Amaoe QU5 is crafted from “super-hard” steel that resists warping. This ensures that the stencil stays flat against the IC even at high temperatures, preventing “solder bridges” (where two balls fuse together). Amaoe QU5 BGA Reballing Stencil-Original

Precise Alignment

The laser-cut patterns are accurate to the micron level. This is critical for PoP (Package on Package) reballing, where the RAM chip sits directly on top of the CPU. If the alignment is off by even $0.01\text{ mm}$ , the device will fail to boot or experience “random restarts.” Amaoe QU5 BGA Reballing Stencil-Original

Usage Tips for Technicians

Cleaning: Always clean the stencil with PCB Cleaner or 99% Isopropyl Alcohol after every use to prevent dried solder paste from clogging the apertures.
Paste Selection: Use a high-quality solder paste (e.g., $183\text{°C}$ or $138\text{°C}$ depending on the component sensitivity).
Pressure: Apply even pressure with tweezers at the center of the IC to ensure no paste leaks under the stencil during the “swipe” phase.
