Below is the comprehensive technical breakdown and specification guide for the original AMAOE MI4 Stencil. AMAOE MI4 Stencil Original XIAOMI
🛠 Product Overview: AMAOE MI4
The MI4 stencil is a “planting tin” net used by technicians to reapplying solder balls (reballing) to Integrated Circuits (ICs) such as the CPU, RAM, and Power Management ICs (PMICs). Amaoe stencils are widely regarded in the industry for their high-temperature resistance and square-hole design, which prevents the solder paste from getting stuck. AMAOE MI4 Stencil Original XIAOMI

📱 Supported Device & Chipset Architecture
The MI4 is not a “universal” Android stencil; it is tailored to the component layout of specific Xiaomi motherboards. Using the correct model-specific stencil ensures that the pitch (distance between solder balls) matches the IC perfectly.
1. Primary Chipset Compatibility
-
Qualcomm MSM8956: Also known as the Snapdragon 650. This is found in the early high-performance mid-range Xiaomi units.
-
MediaTek MT6795: Known as the Helio X10. A flagship processor for its era, common in the Redmi Note series. AMAOE MI4 Stencil Original XIAOMI
2. Verified Device Models
-
Xiaomi Mi Max (1st Gen): Specifically the variants using the Snapdragon 650/652.
-
Xiaomi Redmi Note 2: (Helio X10 version).
-
Xiaomi Redmi Note 3: (Both MediaTek and Snapdragon variants depending on regional IC layout).
3. On-Board ICs Supported
The stencil features dedicated sections for:
-
CPU/RAM Tiered Reballing: Supports the “sandwich” PoP (Package on Package) structure.
-
EMMC/UFS Storage: Flash memory chip reballing.
-
Power Management (PMIC): Small pitch power control chips.
-
WIFI/Audio/RF: Peripheral communication chips.
✨ Key Technical Features
1. Square Hole Technology
Unlike cheaper stencils that use circular etched holes, Amaoe uses laser-cut square apertures.
Why it matters: Square holes allow the solder paste to release more cleanly when the stencil is lifted. This prevents “bridging” (solder balls merging) and ensures a 100% success rate on the first attempt.
2. 0.12mm Precision Thickness
The thickness is mathematically optimized at $0.12\text{mm}$.
-
If the stencil were thinner ($0.10\text{mm}$), the solder balls would be too small to make a secure contact.
-
If thicker ($0.15\text{mm}$), the balls might be too large, causing shorts under the CPU.
3. Anti-Warping Material
The high-grade stainless steel is treated to withstand direct heating. This means you can keep the stencil on the chip while applying heat with a hot air station without the metal “buckling” or warping away from the chip.
💡 Maintenance and Usage Tips
To maintain the “Original” performance of your AMAOE MI4:
-
Cleaning: Use 99% Isopropyl Alcohol (IPA) and a soft-bristled ESD brush after every use. Solder paste residue in the holes will harden and ruin future reballs.
-
Solder Paste: It is recommended to use $183\text{°C}$ leaded solder paste for the best balance between flow and structural integrity.
-
Heat Control: Set your hot air station to approximately $330\text{°C} – 350\text{°C}$ with low airflow to prevent the stencil from moving.
