Mechanic/Amaoe MZ-5 Stencil

The Mechanic/Amaoe MZ-5 is a high-precision BGA reballing stencil designed specifically for professional electronics repair, targeting the Samsung S10 and S10+ series (Exynos and Snapdragon versions). It is widely recognized in the industry for its "black" anti-glare finish and square-hole design.

Below is the detailed product description organized for quick reference.

Technical Specifications Overview

Key Features & Benefits

The MZ-5 stands out due to its specific engineering choices that cater to micro-soldering professionals.

• Anti-Drum Design: The stencil is engineered to remain flat under high heat, preventing the "warping" or "popping" effect often seen in cheaper stencils.

• Square Mesh Holes: Unlike traditional round holes, the square design allows for easier release of solder paste, ensuring uniform solder balls across the entire BGA grid.

• Heat Resistance: Rated for high-temperature stability, allowing for repeated use without deformation.

• Laser Cutting Technology: Each hole is laser-cut with high precision to ensure 1:1 alignment with the original chip pads.

Detailed Chip Compatibility List

The MZ-5 is a "multi-purpose" stencil for the S10 generation. It covers almost every major integrated circuit on the logic board.

Usage Recommendations

To maximize the lifespan of your MZ-5 stencil and ensure a successful reballing process, follow these professional guidelines:

1. Alignment: Ensure the IC is perfectly aligned using a microscope. The black coating helps provide high contrast against the silver pads.

2. Solder Paste: Use high-quality solder paste (e.g., Mechanic 183°C or 138°C depending on the component sensitivity).

3. Heat Application: Apply heat evenly in a circular motion. Because the stencil is 0.12mm thin, it reaches temperature quickly.

4. Cleaning: Clean immediately after use using PCB cleaner or ultrasonic cleaning to prevent solder paste from hardening in the square holes.
