The Amaoe Middle Layer Stencil for the OnePlus Ace 2 (also referred to as the OPPO OnePlus Ace2 5G) is a specialized high-precision tool designed for professional mobile motherboard repair. Specifically, this stencil is used for “reballing” the middle board layers or the audio board ICs—a critical process when a device has suffered from “sandwich” board separation, drop damage, or internal soldering fatigue.

Core Functional Features
1. High-Precision Square Hole Technology
Unlike older circular apertures, the Amaoe Ace2 stencil utilizes square holes. This is a deliberate engineering choice to:
-
Improve Tin Release: Solder paste releases more cleanly from square corners compared to round edges, preventing “stuck” solder.
-
Uniform Ball Formation: It ensures that every BGA (Ball Grid Array) point on the Ace2 middle layer receives the exact same volume of solder. Amaoe Middle Layer Stencil-Original For Ace2
2. $0.12\text{ mm}$ Ultra-Thin Design
Modern smartphones like the Ace 2 use stacked motherboards (sandwich boards). The spacing between these layers is extremely tight. A $0.12\text{ mm}$ thickness is the “sweet spot” for reballing; it is thick enough to provide structural integrity against heat warping but thin enough to prevent over-depositing solder, which causes shorts between the dense pins.

3. Japanese Imported Steel
Amaoe uses high-quality steel sheets often sourced from Japan. This material has a high “memory” property, meaning after it is heated by a hot air gun (which causes the metal to expand), it returns to its original flat shape upon cooling. This prevents the “bulging” effect that cheaper stencils suffer from after just a few uses. Amaoe Middle Layer Stencil-Original For Ace2
Detailed Application Guide
The Ace 2 motherboard architecture is complex. The middle layer connects the logic processing unit with the power and communication modules.
When is this stencil required?
-
WiFi/Bluetooth Failure: Often caused by the middle layer solder joints cracking.
-
No Sound/Audio IC Issues: The “Ace2-2” variant of this stencil specifically targets the audio board components.
-
Device Not Charging/Booting: If the sandwich board loses connection, the power rails won’t reach the CPU.
Recommended Tool Synergy
To achieve the best results with this stencil, the following parameters are recommended:
-
Solder Paste: $183\text{°C}$ or $138\text{°C}$ (Low-melt for middle layers to prevent damaging internal components).
-
Hot Air Station Temperature: Set between $320\text{°C}$ and $350\text{°C}$.
-
Air Flow: Low to medium to prevent the stencil from lifting.
Why Choose “Original” Amaoe?
The market is flooded with “AA” or “1:1” copies. However, the original Amaoe stencil is preferred by technicians because of the Aperture Chamfering. In original stencils, the walls of the holes are polished smooth at a microscopic level. In clones, the laser-cut edges are often jagged, which “grabs” the solder paste and results in missing balls or uneven heights across the chip. Amaoe Middle Layer Stencil-Original For Ace2
Maintenance Tip: Always clean the stencil with 99.9% Isopropyl Alcohol (IPA) immediately after use. If solder paste hardens in the $0.12\text{ mm}$ holes, it can be extremely difficult to remove without damaging the precision edges of the square apertures.
