## Supported IC & Device Compatibility
The SAM4 variant is particularly famous for its support of the “Golden Era” Samsung Exynos chips. Unlike universal stencils, the SAM4 features custom-aligned holes for:
-
Samsung Galaxy A Series: A3, A5, A7 (e.g., A310, A520 models)
-
Samsung Galaxy S Series: S5 Mini
-
Samsung Galaxy J Series: J7 (various versions)
-
Specific Chipsets:
-
CPU: Exynos 7880, 7580, 3470
-
Power: Various Power Management ICs (PMICs) associated with these logic boards.
-
## Key Product Features
-
Anti-Drumming Design: The stencil is designed with a specific tension profile to prevent the “drum effect” (bulging) when high heat is applied. This ensures the stencil stays flat against the IC during the soldering process. Amaoe SAM4 BGA Stencil-Original 0.15mm
-
Square Hole Technology: Amaoe uses square apertures with slightly rounded corners. This allows the solder paste to release more cleanly than traditional circular holes, leading to uniform ball heights. Amaoe SAM4 BGA Stencil-Original 0.15mm
-
Heat-Sink Properties: The 0.15mm thickness provides a perfect balance. It is thick enough to resist warping under a hot air gun but thin enough to allow rapid heat transfer to the solder paste. Amaoe SAM4 BGA Stencil-Original 0.15mm
-
Chemical Resistance: The high-quality steel is resistant to the aggressive fluxes found in high-performance solder pastes, preventing corrosion and ensuring a long service life. Amaoe SAM4 BGA Stencil-Original 0.15mm
## Recommended Usage Parameters
To maximize the lifespan of your original Amaoe stencil and achieve a 100% success rate:
-
Solder Paste: Use a high-quality Sn63/Pb37 (183°C) or Sn42/Bi58 (138°C) paste depending on the IC sensitivity.
-
Air Temperature: Set your rework station between 330°C and 360°C for leaded paste.
-
Air Flow: Keep airflow low to medium (20–40%) to prevent the stencil from lifting or the paste from blowing out of the apertures.
-
Cleaning: Clean with 99% Isopropyl Alcohol (IPA) and a soft-bristle brush immediately after use to prevent paste hardening in the holes.
## Why Choose the 0.15mm Over 0.12mm?
While many modern CPU stencils (like the SAM15+) use a 0.12mm thickness for ultra-fine pitch chips, the SAM4 at 0.15mm is preferred for older or mid-range Exynos chips. These ICs often have slightly larger solder pads and wider pitches; the 0.15mm thickness allows for a larger solder ball volume, ensuring a more robust mechanical and electrical connection between the chip and the PCB.
