Usage Guidelines for Technicians
| Step | Action | Best Practice |
| 1. Preparation | Clean the IC chip surface thoroughly. | Use high-quality IPA (Isopropyl Alcohol) to remove oxidation. |
| 2. Positioning | Place the chip accurately under the stencil aperture. | Use a high-magnification microscope for perfect pad-to-hole alignment. |
| 3. Paste Application | Apply a thin, even layer of solder paste. | Use a metal scraper to ensure a smooth, level finish across the stencil. |
| 4. Heating | Apply controlled heat using a hot air rework station. | Maintain stable airflow to prevent stencil lifting or solder splatter. |
| 5. Post-Process | Gently lift the stencil once the solder cools. | Ensure the stencil is cleaned immediately to prevent flux/solder buildup. |
