Device Compatibility (Black Shark Series)
While the chips can be found in various brands (Xiaomi, Vivo, Oppo), the BS1 layout is optimized for the Black Shark gaming phone lineup:
-
Black Shark 3 / 3 Pro / 3S
-
Black Shark 4 / 4 Pro / 4S
-
Black Shark 5 (Select ICs)
Key Features & Maintenance
1. 45-Degree Square Hole Design
Unlike cheaper stencils with vertical holes, Amaoe uses a 45-degree square aperture. This prevents the solder balls from getting “stuck” in the stencil when you lift it. It ensures that the solder paste is released cleanly, resulting in uniform, perfectly spherical solder balls. Amaoe Stencil-Original BS1
2. Heat Deformation Resistance
The 0.12 mm stainless steel is treated to withstand the thermal expansion that occurs during reballing. This prevents “bubbling” or warping of the stencil when applying heat with a hot air station, which is critical for avoiding solder bridges between tiny CPU pads. Amaoe Stencil-Original BS1
3. Optimal Thickness
At 0.12 mm, the stencil provides the exact volume of solder paste required for modern mobile ICs. A stencil that is too thick results in oversized balls that bridge; one that is too thin results in weak connections. Amaoe Stencil-Original BS1
4. Maintenance Tips
-
Cleaning: Use 99% Isopropyl Alcohol (IPA) and a soft ESD brush immediately after use to prevent solder paste from hardening in the apertures.
-
Storage: Keep the stencil flat. Avoid bending or applying heavy weight, as even a slight crease can ruin the alignment for fine-pitch BGAs.
-
Usage: Use a high-quality solder paste (e.g., Mechanic or Relife 183°C) for best results with this specific thickness.
Note: The Amaoe BS1 is a professional-grade tool. It is specifically designed for technicians performing motherboard-level repairs involving CPU transplantation or fixing “dead” devices caused by solder joint fractures under flagship processors.
