## Supported Chipsets & BGA Patterns
The EMMC-3 is a “multi-purpose” memory stencil. It doesn’t just cover one chip; it is a collection of the most common storage footprints used by manufacturers like Samsung, SK Hynix, and Micron.
-
EMMC / EMCP: BGA153, BGA162, BGA169, BGA186, BGA221, BGA254, BGA529.
-
UFS / UMCP: UFS 2.0, 2.1, 3.0, 3.1 (BGA153, BGA254, BGA297).
-
Other Components: LPDDR RAM, NAND Flash, and some PCI-E based storage chips.
-
Common BGA Types: * BGA153/169: Standard EMMC found in mid-range Androids.
-
BGA221: Common in high-end EMCP configurations.
-
BGA254: The modern standard for high-speed UFS storage.

## Key Features & Advantages
1. Square-Round Hole Design
One of the biggest frustrations in reballing is the solder paste getting “stuck” in the stencil holes. Amaoe utilizes a square-round aperture. The square base allows for maximum solder volume, while the rounded corners prevent the paste from clinging to the edges, allowing for a clean “release” once the stencil is lifted.

2. 0.15mm Precision Thickness
While CPU stencils often use 0.12mm, memory chips benefit from the 0.15mm thickness of the EMMC-3. This slight increase provides a more robust solder ball that ensures better connectivity on larger pads, which are common on storage ICs compared to the ultra-fine pitch of a CPU.

3. Heat Resistance and Elasticity
Cheap stencils often “bow” or “pop” when hit with a heat gun at 350°C. The Amaoe Original series is treated to be “super-hard” but elastic. This means it can expand slightly under heat and return to its perfectly flat shape once cooled, preventing the common “solder bridging” caused by warped metal. Amaoe EMMC 3 BGA Stencil-Original
4. Alignment Accuracy
The stencil features clear silk-screened markings and precise positioning for the ICs. This reduces the setup time for technicians, as the chip “locks” into the etched boundary of the stencil pattern easily. Amaoe EMMC 3 BGA Stencil-Original
## Usage Recommendations
To get the most out of your Amaoe EMMC-3, follow these professional tips:
-
Cleaning: Always clean the stencil with mechanic 530 or high-purity IPA after every use. Solder paste residue in the holes will cause the next chip to fail.
-
Paste Selection: Use a high-quality 183°C (Medium Temp) solder paste for memory chips to ensure a strong mechanical bond.
-
Heat Profile: Use a nozzle that covers the entire chip area. For a 0.15mm stencil, a temperature of 330°C–350°C with low airflow is usually the “sweet spot.”
Note: Ensure you are buying the “Original” Amaoe with the holographic or verified branding, as “copy” versions often use inferior steel that warps after 2-3 uses.
