In-Depth Component Support
The MU2 stencil is particularly valued because it covers a broad range of integrated circuits (ICs) found in mid-to-high-range smartphones (Xiaomi, Oppo, Vivo, etc.). Below is a breakdown of the specific chips typically supported on this plate: Amaoe MU2 BGA Reballing Stencil-Original
1. CPU & Processor Support
The stencil includes dedicated areas for popular MediaTek processors. These require extreme precision due to the high pin count and tight pitch.
-
MT6755V
-
MT6750V
-
MT6735V
-
MT6753V
2. Power Management (PMIC)
Power ICs are the most frequently replaced components after water damage or charging surges. The MU2 covers:
-
MT6353P / MT6351P
-
MT6328V / MT6350V
3. Memory & Storage (BGA Variations)
The MU2 is often used for “sandwich” reballing or memory swaps. It supports various BGA patterns including:
-
BGA 221
-
BGA 153
-
BGA 254 (Depending on the specific MU2 revision)
Design Excellence: Why Technicians Choose MU2
The “Original” Amaoe stencils utilize a proprietary manufacturing process that addresses three major pain points in BGA reballing:
1. The “Anti-Bulge” Design
Cheap stencils expand unevenly when hit with a heat gun (typically at $330°C$ to $350°C$). This causes the stencil to bow upward, allowing solder paste to bridge between pins. The MU2 uses a specific grade of Japanese steel that maintains flatness under localized heat. Amaoe MU2 BGA Reballing Stencil-Original
2. Square Holes with Rounded Corners
If a stencil hole is a sharp square, the solder ball often gets stuck inside the stencil when you try to lift it. Amaoe uses laser-cut square holes with microscopic internal chamfering and rounded corners. This ensures the solder balls stay on the chip pads, not in the stencil.

3. Heat Dissipation Vents
If you look closely at an original MU2, you will notice small “non-functional” laser cuts or dimples in areas without chips. These act as expansion joints, allowing the metal to breathe without distorting the critical alignment areas. Amaoe MU2 BGA Reballing Stencil-Original
Best Practices for Using the MU2 Stencil
To maximize the lifespan of your Amaoe stencil and ensure a 100% success rate on the first “swing,” follow these professional guidelines:
-
Cleaning: Always clean the stencil with Mechanic 850 or 99% Isopropyl Alcohol (IPA) before use. Even a microscopic speck of old flux will cause a solder ball to stick.
-
Paste Consistency: Use a “dry” solder paste (183°C Lead-Saturated). If your paste is too oily, dab it on a lint-free cloth first to remove excess flux.
-
Thermal Management: Use a nozzle that covers the entire chip area. For the 0.12mm MU2, a temperature of $340°C$ with a low airflow (3 or 4 on most stations) is the “sweet spot” to prevent the stencil from dancing.
-
Pressure: Use curved tweezers to hold the stencil down at the edges of the IC, never in the center, to avoid creating a concave dip.
Summary of Advantages
-
Precision: $0.12mm$ thickness is the industry gold standard for balance between durability and ease of solder melting.
-
Efficiency: Multiple IC footprints on one plate reduce the need for a massive library of single-chip stencils.
-
Durability: Unlike “black” stencils that can flake, the MU2’s polished steel finish is rust-resistant and handles thousands of heat cycles.
Note: Beware of “A-grade” or “AAA” clones. Genuine Amaoe stencils feature the distinct etched logo and holographic packaging. The clones often use 0.1mm steel which warps instantly under heat. Amaoe MU2 BGA Reballing Stencil-Original
