AMAOE KIRIN9020-HI36C0 STENCIL
AMAOE KIRIN9020-HI36C0 BGA Reballing Stencil
The AMAOE KIRIN9020-HI36C0 (also categorized under the premium HW19 series series matrix) is an ultra-high precision BGA reballing stencil manufactured specifically for flagship Huawei repair ecosystems. It is purpose-built to service the cutting-edge HiSilicon Kirin 9020 (HI36C0) System-on-Chip (SoC) architecture alongside its stacked RAM layers, storage modules, and peripheral sub-ICs.
Engineered from imported premium Japanese steel and cut via high-precision CNC laser micro-etching, this stencil is essential for tier-1 micro-soldering labs executing advanced motherboard swaps, CPU reflows, and data recovery operations on flagship models like the Huawei Mate 70 series and Mate X6 foldable platforms.

Structural & Performance Innovation
1. Advanced 0.12mm Solder Height Standardization
In multi-tiered smartphone architectures (such as RAM stacked directly over the CPU), ball height accuracy must be absolute. The 0.12mm thickness is deliberately engineered to prevent the two common pitfalls of BGA rework: it deposits a structural volume dense enough to prevent cold joints or stress cracks, yet shallow enough to eliminate lateral bridging under highly compressed layouts.
2. Surface-Tension Breaking Apertures
Traditional generic circular stencil openings have vertical walls that naturally trap sticky flux and microscopic paste. AMAOE implements laser-etched square openings built with microscopic radial corner curves. This configuration mechanically reduces the surface tension between the paste and the steel, ensuring that when the stencil is lifted, 100% of the uniform solder squares remain intact on the chipset pads.
3. High Thermal Sticking Resistance
Flagship chip micro-soldering requires sustained high temperatures. The unique SUS301 Japanese steel blend features high elasticity under thermal load. This eliminates the risk of localized thermal expansion causing the center of the stencil to "bow" or bulge away from the CPU, keeping the paste execution perfectly flat.
