Key Product Features

1. Precision Laser Cutting

Unlike generic stencils that use chemical etching, the Amaoe Original uses high-precision laser cutting. This ensures that each aperture is uniform in size and perfectly vertical, preventing solder paste from getting trapped or forming “bridges” between pads.

2. Optimized 0.12mm Thickness

At $0.12\text{ mm}$ , the stencil strikes the perfect balance between flexibility and structural integrity. This specific thickness is calibrated to deposit the exact volume of solder paste required to create uniform $BGA$ (Ball Grid Array) heights across the middle frame.

3. Anti-Bulging Technology

One of the biggest challenges in motherboard “sandwich” repair is stencil bulging under heat. Amaoe stencils feature heat-dissipation grooves and a material composition that minimizes thermal expansion, ensuring the stencil remains flat against the PCB during the heating process.

4. Chamfered Square Holes

The holes are designed with a slight chamfer (taper). This “square-round” design allows the solder paste to release effortlessly from the stencil, leaving behind clean, sharp-edged solder deposits that melt into perfect spheres.

Usage Scenarios & Repair Context

The Samsung Note 20 series utilizes a dual-layered motherboard. To perform repairs on internal components—such as the Exynos 990 or Snapdragon 865+ CPU, or the UFS 3.0 storage—the technician must “split” the two layers.

Once the repair is completed, the Amaoe Middle Layer Stencil is used to:

Clean and Prep: Align the stencil over the middle frame of the bottom board.
Paste Application: Spread solder paste across the stencil; the $0.12\text{ mm}$ depth ensures consistent ball size.
Reflow: Use a specialized heating platform or hot air station to melt the paste into uniform balls.
Re-Join: Align the top board onto the newly reballed bottom board and heat until the layers fuse.

Maintenance and Care

To ensure the longevity of your Amaoe stencil, it is recommended to:

Clean Immediately: Use 99% Isopropyl Alcohol (IPA) and a soft brush to remove residual solder paste after every use.
Avoid Physical Stress: Do not fold or crease the stencil, as any slight bend will prevent the flush contact required for precise reballing.
Store Flat: Keep the stencil in its original protective sleeve or a magnetic storage book.
