Key Features & Design Philosophy
1. The “Square Hole” Advantage
Amaoe is famous for its square-hole design with rounded corners. Traditional round holes often trap solder paste due to surface tension. The SAM11 design ensures that when you lift the stencil after applying the paste, the “bricks” of solder remain perfectly formed on the IC pads, reducing the risk of bridging or “ghosting.”
2. Precise Thickness (0.12mm)
The thickness of a stencil is a delicate balance. If it’s too thick, you get oversized solder balls that short-circuit; too thin, and the joint is weak. At 0.12mm, the SAM11 provides the exact volume of solder required for the tight pitches found in the Samsung S9/Note 9 generation logic boards. Amaoe SAM11 BGA Reballing Stencil
3. Material Durability
Constructed from imported Japanese steel, these stencils are designed to withstand the rapid thermal expansion that occurs when using a hot air station. This prevents the “bulging” effect that can ruin a reballing attempt mid-way through the process. Amaoe SAM11 BGA Reballing Stencil
Supported Components (IC List)
The SAM11 is a “Multi-IC” stencil, meaning it isn’t just for one chip. It covers the primary “heavy hitters” on the motherboard:
-
Main Processor (CPU): Specifically tailored for the Exynos 9810 or Snapdragon 845 layouts.
-
Memory (RAM): The PoP (Package on Package) RAM that sits directly on top of the CPU.
-
Power Management (PMIC): Multiple smaller grids for the secondary power chips.
-
Storage (UFS): Flash memory chips.
Best Practices for Using the SAM11
To get the most out of this professional-grade tool, follow these industry-standard steps: Amaoe SAM11 BGA Reballing Stencil
-
Cleaning: Ensure the IC and the stencil are 100% free of old flux and debris. Use 99.9% Isopropyl Alcohol (IPA). Amaoe SAM11 BGA Reballing Stencil
-
Alignment: Align the IC under the stencil. The SAM11 features high-transparency steel that makes visual alignment easier under a microscope. Amaoe SAM11 BGA Reballing Stencil
-
Paste Application: Use a high-quality solder paste (e.g., $Sn63/Pb37$ or lead-free $Sn96.5/Ag3.0/Cu0.5$ depending on your preference). Apply with a firm squeegee. Amaoe SAM11 BGA Reballing Stencil
-
Heat Management: Set your hot air station to approximately 330°C – 350°C with low airflow. Hold the stencil down with tweezers to ensure it remains flat during the “reflow” phase. Amaoe SAM11 BGA Reballing Stencil
Pro Tip: If the stencil warps slightly during heating, you are likely applying too much heat too quickly. Use a pre-heater or a lower air-flow setting to allow the metal to expand gradually. Amaoe SAM11 BGA Reballing Stencil
Comparison: Amaoe vs. Standard Stencils
-
Standard Stencils: Often made of cheaper alloys that warp after 5-10 uses. Holes may have burrs that trap solder.
-
Amaoe SAM11: Laser-polished apertures. The “3D” feel of the stencil allows it to “lock” onto the IC, providing a more stable platform for reballing.
