Key Features & Benefits
1. High-Precision Etching
The Amaoe stencils utilize laser-cutting technology that ensures every hole is perfectly vertical and consistent. This is critical for the Samsung S20/S21 series, as the motherboard utilizes a double-layered (stacked) PCB. Even a minor misalignment in the middle frame can result in a short circuit or a “no power” state. Amaoe For Samsung Galaxy S20/S21 plus
2. $0.12\text{mm}$ Optimized Thickness
Unlike cheaper $0.10\text{mm}$ stencils that can warp or $0.15\text{mm}$ stencils that apply too much paste, the $0.12\text{mm}$ gauge is considered the “Goldilocks” zone for modern Samsung logic boards. It provides enough structural integrity to withstand heat while ensuring the solder balls are the exact height required for a perfect seat. Amaoe For Samsung Galaxy S20/S21 plus
3. Thermal Stability
Samsung repairs often require high temperatures (especially when removing the underfill around the Exynos or Snapdragon CPUs). These stencils are crafted from high-tensile stainless steel that resists “blooming” or expansion when hit with $350^{\circ}\text{C}$ to $400^{\circ}\text{C}$ air.

4. Model Coverage
-
SAM:15 Series: Typically covers the S21 series, including the Snapdragon 888 and Exynos 2100 CPU regions.
-
Middle Frame Stencils: Specifically designed for “re-marrying” the top and bottom logic boards after a sandwich separation.
Usage Recommendations
To get the most out of your Amaoe stencil, it is recommended to use 183°C Lead-Free Solder Paste or 138°C Low-Temperature Paste depending on the specific component. Always clean the stencil with specialized PCB cleaner or 99% Isopropyl Alcohol immediately after use to prevent solder residue from hardening in the apertures. Amaoe For Samsung Galaxy S20/S21 plus
