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.
