The Amaoe Stencil-Original HW 1 is a high-precision BGA (Ball Grid Array) reballing stencil specifically engineered for Huawei-brand smartphones. Amaoe is widely regarded in the microsoldering community for its “Square Hole” technology, which prevents solder balls from getting stuck—a common headache for repair technicians.

Key Features & Design Philosophy
1. The “Square Hole” Advantage
Most generic stencils use circular holes. While these match the shape of a solder ball, they often create a vacuum effect or surface tension that causes the solder paste to stick to the stencil rather than the chip. The HW 1 utilizes square holes with chamfered edges. This design reduces the contact area between the paste and the stencil walls, allowing for a “clean release” once the heat is applied.
2. Material Integrity
The HW 1 is manufactured from high-toughness stainless steel. In the world of microsoldering, heat management is everything. Low-quality stencils often “pot” or bulge when hit with a heat gun at $350°C$. Amaoe stencils are designed to remain flat under high temperatures, ensuring that the solder balls don’t bridge (merge) underneath the plate.
3. Precision Alignment
The stencil is etched with high-contrast markings that correspond to the IC (Integrated Circuit) orientation. This is crucial for the Kirin processors found in the Mate and P-series devices, which have dense pinouts. The 0.12 mm thickness is the “Goldilocks” zone for reballing; it’s thick enough to provide structural integrity but thin enough to ensure the solder balls are the exact height required for the motherboard’s pads.
Chipset Compatibility Deep Dive
The HW 1 is an “Essential” stencil because it covers the foundational Kirin architecture that powered Huawei’s rise in the mid-2010s.
-
Kirin 950/955: Found in the flagship Mate 8 and P9. These chips were some of the first to use FinFET technology, requiring extremely precise reballing during CPU swaps or RAM sandwiches.
-
Kirin 620: The workhorse for Huawei’s mid-range “Lite” and “Honor” models.
-
Power Management & RF: While primarily known for CPUs, the HW 1 often includes layouts for accompanying Power Management ICs (PMICs) and WiFi modules used in that specific hardware generation.
Best Practices for Using the HW 1
To get the most out of this specific stencil, technicians should follow a standardized workflow:
-
Cleaning: Ensure the IC is completely free of old solder and flux. Use a copper wick and isopropyl alcohol.
-
Alignment: Place the HW 1 over the chip. The square holes should perfectly frame the silver pads on the IC.
-
Paste Application: Use a high-quality solder paste (usually $Sn63/Pb37$ or a lead-free equivalent). Apply with a spatula, ensuring even distribution across the square holes.
-
Heat Profile: Use a nozzle that covers the entire chip area. Set your rework station to approximately $330°C – 350°C$ with low airflow to prevent the stencil from moving or the paste from blowing away.
Why “Original” Matters
There are many “A-moe” or “Am-oe” clones on the market. The Original HW 1 is distinguished by its laser-etched logo and the specific “hand-feel” of the steel. Clones often use 0.10 mm steel which is prone to warping, or the holes are not perfectly centered, leading to misaligned solder balls and potential short circuits.
The HW 1 remains a staple for data recovery specialists. Even as newer Kirin chips (like the 9000 series) emerge, the HW 1 is the primary tool for reviving older devices to extract encrypted user data.
