Key Components & Chipset Support
The SAM5 isn’t just one hole pattern; it is a multi-stencil plate. Here is a breakdown of the specific chips this stencil is engineered to reball:
-
CPU/RAM Stack: Optimized for the PoP (Package on Package) design used in Samsung flagship processors. Amaoe SAM5 Bga Reballing Stencil-Original
-
Exynos Series: Support for mid-to-high tier Exynos 9810, 9820, and 9825 variants. Amaoe SAM5 Bga Reballing Stencil-Original
-
Qualcomm Snapdragon: Patterns for the Snapdragon 845 and 855 architectures. Amaoe SAM5 Bga Reballing Stencil-Original
-
Power Management (PMIC): Precision patterns for Hi-Power and Sub-PMIC chips.
-
Universal BGA: Various pitch sizes ($0.3mm$ to $0.5mm$) for miscellaneous logic ICs.
Why the SAM5 is a Industry Favorite
To understand the value beyond the table, we have to look at the metallurgical engineering involved:
1. The “Square Hole” Advantage
Most cheap stencils use circular holes. Amaoe uses square holes with rounded corners. When you apply solder paste, the square shape allows for a higher volume of paste, while the rounded corners ensure the “slug” of paste releases cleanly without sticking to the stencil walls.

2. Heat Sink Grooves
If you look closely at a SAM5, you’ll see tiny etched lines between the chip patterns. These are expansion joints. When you hit the stencil with a $350^\circ\text{C}$ heat gun, metal naturally expands. These grooves allow the metal to expand outward rather than upward, preventing the dreaded “stencil bulge” that causes solder bridges. Amaoe SAM5 Bga Reballing Stencil-Original
3. 0.12mm Thickness Precision
Thickness is the most debated spec in reballing.
-
0.10mm: Often too thin; warps easily.
-
0.15mm: Often too thick; results in solder balls that are too large, causing shorts.
-
0.12mm (SAM5): The “Goldilocks” zone. It provides enough structural integrity to stay flat while ensuring the solder ball height is perfectly spec’d for Samsung’s tight motherboard tolerances.
Usage Professional Tips
Note: Even with a high-end Amaoe stencil, your technique matters. Always clean the stencil with 99% IPA (Isopropyl Alcohol) before and after use to ensure no flux residue clogs the $0.12mm$ apertures. Amaoe SAM5 Bga Reballing Stencil-Original
-
Solder Paste Choice: Use a high-quality “No-Clean” paste with a $183^\circ\text{C}$ melting point (Leaded) for the best results with this stencil. Amaoe SAM5 Bga Reballing Stencil-Original
-
Heat Profile: Use a nozzle that covers the entire chip area. For the SAM5, a temperature of 320°C – 350°C with low airflow is recommended to prevent the stencil from lifting. Amaoe SAM5 Bga Reballing Stencil-Original
