Detailed Feature Breakdown
1. Precision 0.12mm Thickness
The 0.12mm thickness is the industry standard for smartphone CPU reballing. It provides a perfect balance between structural integrity and the correct volume of solder paste. This specific thickness ensures that the solder balls are neither too small (which causes weak connections) nor too large (which causes bridging/shorts). Amaoe HU2 Stencil-Original
2. Square Hole Technology
Unlike traditional round-hole stencils, the HU2 utilizes Square Hole apertures. This design minimizes the surface tension between the solder paste and the stencil walls. When you lift the stencil after applying the paste, the “bricks” of solder remain firmly on the chip pads without sticking to the edges of the stencil, significantly reducing rework.

3. Advanced Material Construction
The stencil is manufactured from Japanese imported steel. This material is chosen for its “memory” properties; it can withstand the thermal shock of a hot air gun (reflux) without permanently deforming or “bubbling.” The surface is typically finished with a matte or brushed coating to reduce glare under microscope lights.

4. Broad Compatibility (Hi Series)
The “HU” designation stands for Huawei. The HU2 specifically targets several generations of mid-to-high-end Kirin processors. It is commonly used for:
-
Hi6250: Found in many Honor and P-series Lite models.
-
Hi3660 (Kirin 960): Found in flagship devices like the Huawei P10 and Mate 9.
-
Hi6220: Integrated into various budget-friendly Huawei smartphones.
Application & Best Practices
To achieve the best results with the Amaoe HU2, technicians generally follow these steps:
-
Preparation: Clean the IC chip thoroughly using a soldering iron and desoldering wick to ensure the pads are flat.
-
Alignment: Place the HU2 stencil over the chip. The laser-cut holes should align perfectly with the BGA pads. Due to its magnetic properties, it works best when used with a magnetic reballing station.
-
Paste Application: Apply a high-quality solder paste (usually 183°C or 138°C depending on the sensitivity of the chip). Use a scraper to spread the paste evenly across the square holes.
-
Heating: Use a hot air rework station set to approximately 300°C–330°C with low airflow. The solder will melt and form uniform spheres.
-
Cooling & Cleaning: Allow the stencil to cool before removing the chip. Clean the stencil immediately with PCB cleaner to prevent dried flux from clogging the fine mesh.
Why Choose the Original Amaoe?
Counterfeit stencils often use inferior alloys that warp after just one or two uses. The Original Amaoe HU2 is etched with high-precision lasers, ensuring that every hole is identical in size and depth. This consistency is vital for the complex 0.3mm to 0.4mm pitch found in modern Kirin processors. Amaoe HU2 Stencil-Original
