This range allows technicians to work on a wide variety of devices, including Apple iPhones (Logic board NANDs), Samsung Galaxy series, and various MediaTek (MTK) or Qualcomm-based Android devices that utilize these specific pin layouts for storage chips.

Key Technical Advantages

1. Anti-Drum/Anti-Deformation Technology

One of the primary frustrations in reballing is the “drumming” effect, where the stencil warps or bulges under the heat of a hot air gun. Amaoe stencils are manufactured using a specialized cooling process for the stainless steel, ensuring the plate remains flat even when subjected to the high temperatures required for lead-free solder ( $217\text{°C}$ and above).

2. Square-Round Aperture Design

Unlike cheaper stencils with simple circular or square holes, the NAND1 utilizes a square-round design. The square base allows for a higher volume of solder paste to be deposited, while the rounded corners facilitate a cleaner release of the stencil once the paste is applied. This prevents the “pasting” effect where solder remains stuck inside the stencil holes. Amaoe Nand1 BGA Reballing Stencil-Original

3. Precise Pin Alignment

The laser-cutting process used by Amaoe ensures that the pitch (the distance between the centers of adjacent balls) is accurate to within microns. This is critical for NAND chips where a single bridged connection or a missing ball can result in a “Data Corrupt” error or a device failing to boot. Amaoe Nand1 BGA Reballing Stencil-Original

4. Material Durability

The use of SUS304 stainless steel provides excellent corrosion resistance. This is particularly important because many fluxes used in soldering are mildly acidic; the Amaoe stencil resists pitting and oxidation, allowing it to be cleaned with ultrasonic cleaners or IPA (Isopropyl Alcohol) repeatedly without degrading.

Usage Tips for Best Results

To maximize the lifespan of your Amaoe NAND1 stencil and ensure $100\%$ reballing success:

Solder Paste Choice: Use a high-quality solder paste with a $183\text{°C}$ melting point (Leaded) for easier rework, or $217\text{°C}$ (Lead-free) to match original manufacturer specs. Amaoe Nand1 BGA Reballing Stencil-Original
Alignment: Use a microscope to ensure every pad is perfectly centered in the stencil aperture before applying paste.
Cleaning: Always clean the stencil immediately after use. Dried solder paste in the $0.15\text{mm}$ holes is difficult to remove and can cause future alignment issues.
Heat Application: Start with low airflow to avoid blowing the solder paste out of the holes, and move the heat gun in a circular motion to ensure even reflow across the entire chip surface. Amaoe Nand1 BGA Reballing Stencil-Original
