Key Features & Design Philosophy
1. Material Integrity
The AU2 utilizes high-quality stainless steel that undergoes a specific tempering process. This ensures that the stencil remains flat even after repeated exposure to heat guns. Unlike cheaper alternatives, Amaoe stencils are less prone to “buckling” or “doming,” which is the leading cause of solder bridging during the reballing process.
2. The 0.12mm Standard
The thickness of 0.12mm is considered the “sweet spot” for modern BGA repair.
-
Thinner stencils often lead to insufficient solder ball height, causing poor connectivity. Amaoe AU2 BGA Stencil-Original
-
Thicker stencils can cause the solder paste to get stuck in the holes or create balls that are too large, leading to shorts. Amaoe AU2 BGA Stencil-Original
3. Square-Round Hole Technology
The holes are laser-cut with a slight taper and rounded corners. This design is crucial because it allows the solder paste to release cleanly from the stencil when it is lifted. It also prevents the “tin beads” from sticking to the corners of the stencil holes, ensuring every pad on the chip receives an equal amount of solder. Amaoe AU2 BGA Stencil-Original
Chipset Compatibility & Layout
While the AU2 is labeled “Universal,” it is specifically curated to include footprints for common integrated circuits found in mid-to-high-end smartphones.

Usage Guidelines for Optimal Results
To maximize the lifespan of your Amaoe AU2 and ensure a 100% success rate in reballing, follow these professional tips:
Pro Tip: Always clean the stencil immediately after use. Dried solder paste in the micro-perforations is the primary cause of uneven reballing in subsequent repairs.
Recommended Temperature Settings
When using the AU2, your hot air station settings are critical to prevent thermal stress:
-
Preheating: Set your station to approximately 250°C with low airflow to dry the paste.
-
Reflow: Increase to 320°C – 350°C (depending on your solder paste lead/lead-free content) to form the balls.
Solder Paste Selection
For the AU2, a 183°C (Sn63/Pb37) medium-temperature solder paste is recommended for most repairs. If you are working on high-heat components, a lead-free 217°C paste may be used, though it requires more precise heat control to avoid warping the stencil.
Maintenance and Care
| Action | Frequency | Method |
| Cleaning | After every use | Use 99% Isopropyl Alcohol (IPA) and a soft-bristled brush. |
| Storage | Continuous | Store flat in a protective sleeve; do not bend or place heavy objects on top. |
| De-fluxing | Weekly | Use an ultrasonic cleaner if paste residue becomes stubborn in the corners. |
Summary of Benefits
The Amaoe AU2 is not just a piece of metal; it is a precision-engineered tool that reduces the margin of error in micro-soldering. By providing consistent solder ball height and perfect alignment, it minimizes the risk of damaging expensive motherboards during the repair process.
