Key Feature Breakdown
1. High-Precision Laser Cutting
Amaoe utilizes advanced CNC laser technology to create “square-round” apertures. Unlike cheaper stencils with jagged edges, these holes are tapered and polished. This ensures that the solder paste releases cleanly without sticking to the walls of the stencil, resulting in uniform solder balls across the entire interposer.

2. Thermal Stability (Anti-Deformation)
The Redmi K30 Pro motherboard requires significant heat for desoldering and reballing. This stencil is crafted from specialized steel that resists “warping” or “doming” when subjected to hot air. This stability is critical for middle-layer work, as even a $0.01\text{ mm}$ lift can cause solder bridging between the two board halves. Amaoe Redmi K30 Pro Middle Layer Stencil-Original
3. $0.12\text{ mm}$ Thickness Optimization
The thickness of $0.12\text{ mm}$ is the industry standard for the Snapdragon 865 series. It provides the exact volume of solder paste required to bridge the gap between the logic board and the signal board, ensuring a robust connection that survives the mechanical stress of daily phone use.

4. Cooling & Alignment Vents
The stencil includes peripheral holes and markings that assist in aligning the stencil perfectly with the motherboard’s alignment pins and ground pads. This reduces the setup time and increases the success rate of the “first-time” reball. Amaoe Redmi K30 Pro Middle Layer Stencil-Original
Application and Usage
The middle layer of the Redmi K30 Pro is a complex grid of pads that connects the upper and lower PCB layers. This stencil is used during the “Planting” phase:
-
Cleaning: After separating the layers, all old solder is removed from the interposer pads.
-
Alignment: The Amaoe stencil is placed over the bottom board.
-
Paste Application: Low-melt or medium-melt solder paste (typically $183^\circ\text{C}$ or $158^\circ\text{C}$) is scraped across the stencil.
-
Reflow: Hot air is applied to form the balls, and the stencil is removed.
-
Joining: The top board is then aligned and heated until the two layers fuse.
[!TIP]
Pro Tip: When using the Amaoe Middle Layer stencil, ensure you use a high-quality “no-clean” solder paste. Given the $0.12\text{ mm}$ precision, any impurities in the paste can cause “solder beads” which may short out the middle frame.
