When it comes to EMMC (Embedded MultiMediaCard) and EMCP (Embedded Multi-Chip Package) storage chips, their stencils are the gold standard for mobile technicians. AMAOE Stencil Original EMMC/EMCP
Below are the full specifications for the original AMAOE EMMC/EMCP stencil series. AMAOE Stencil Original EMMC/EMCP
Technical Overview
AMAOE stencils are crafted from imported Japanese high-alloy steel. This material is chosen for its “memory” properties—meaning it can withstand the high heat of a rework station without permanent warping, returning to its flat state once cooled. The holes are CNC-machined with a square-hole design, which allows the solder balls to form more uniformly and release from the mesh without getting stuck.

Model Variations & Supported ICs
AMAOE categorizes their memory stencils into specific series (EMMC-1, EMMC-2, EMMC-3). Each series covers different BGA (Ball Grid Array) footprints.
1. EMMC-1 / EMCP Series
This is the “classic” set, covering the most common legacy and mid-range mobile storage chips found in Android devices. AMAOE Stencil Original EMMC/EMCP
| Model Number | Compatible BGA Footprints | Common Applications |
| BGA 153 | 153 Pins | Standard EMMC (Samsung, Hynix) |
| BGA 162 | 162 Pins | EMCP (Memory + RAM combo) |
| BGA 169 | 169 Pins | High-capacity EMMC (Tablets/TVs) |
| BGA 186 | 186 Pins | Specialized EMCP chips |
| BGA 221 | 221 Pins | Modern High-speed EMCP/UFS |
| BGA 254 | 254 Pins | UFS 2.1 / 3.0 Storage |
2. EMMC-2 Series (Enhanced)
The EMMC-2 series often focuses on refined layouts for newer Samsung Exynos and Qualcomm-based storage architectures. It is frequently sold as a “6-in-1” or “Multi-purpose” template.

3. EMMC-3 / UFS Series (Universal & New Gen)
The EMMC-3 is the most comprehensive modern version, supporting a massive array of chipsets including LPDDR and PCIE-based storage.
| Supported BGA | Purpose |
| BGA 110 | NVMe / PCIE Storage |
| BGA 297 | High-density EMCP |
| BGA 60 / 70 | LPDDR RAM / Specialized NAND |
| BGA 200 | High-end UFS 3.1+ |
Physical Design Attributes
Square vs. Round Holes
Traditional stencils use round holes. However, AMAOE utilizes Square-Round technology.
-
The Logic: Square holes have a larger surface area at the base. When you scrape solder paste, the square shape fills more effectively. During heating, the solder naturally pulls into a sphere due to surface tension. The square corners provide “breathing room,” ensuring the stencil doesn’t “lock” onto the newly formed balls.

Anti-Warping Cooling Vents
If you look closely at an original AMAOE stencil, you will notice tiny non-functional “etched” patterns or slight gaps between IC zones. These act as thermal expansion joints. When the steel expands under a $350\text{°C}$ heat gun, these joints absorb the movement so the center of the stencil doesn’t “pop” or “bubble” up, which is the leading cause of solder bridging.

Usage Recommendations
To maintain the integrity of an original AMAOE stencil:
-
Cleaning: Use 99% Isopropyl Alcohol (IPA) and a soft ESD brush. Avoid metal scrapers that can scratch the polished surface. AMAOE Stencil Original EMMC/EMCP
-
Paste Choice: For EMMC/EMCP, a 183°C (Sn63/Pb37) leaded solder paste is recommended for better flow and durability compared to lead-free alternatives. AMAOE Stencil Original EMMC/EMCP
-
Temperature: Set your hot air station between 300°C – 350°C with low airflow (to prevent blowing the stencil out of alignment). AMAOE Stencil Original EMMC/EMCP
