Key Features & Professional Advantages
Precision Engineering
The stencil utilizes 0.12 mm thickness, which is the industry standard for mobile IC reballing. This thickness ensures that the solder balls are neither too large (causing bridges) nor too small (causing weak joints). The laser-cut square holes are slightly tapered to allow for easier release of solder paste.
Thermal Stability
One of the “Original” Amaoe hallmarks is the anti-drum design. High-quality Japanese steel prevents the stencil from bulging or warping when heat is applied from a hot air gun. This ensures that the stencil remains flat against the chip, preventing “tin leakage” or solder bridges between pads.
Ergonomics
The stencil is designed with a specific “Hand-feel” (often referred to by technicians as “Abao” style). It features a smooth surface that is easy to clean with IPA (Isopropanol) and a layout that allows for easy alignment without the need for complex mounting jigs.
Maintenance & Usage Tips
-
Alignment: Always use a microscope for alignment to ensure every pad is perfectly centered within the stencil aperture.
-
Solder Paste: Use high-quality 183°C (Leaded) or 138°C (Low-temperature) solder paste depending on the sensitivity of the chip.
-
Cleaning: After each use, clean the stencil immediately with a soft brush and PCB cleaner to prevent dried solder paste from clogging the micro-apertures.
