Decoding Ultra-Clean Surfaces, Uniform Peel Force, and High-Temperature Stability for Ceramic Capacitor Manufacturing
Product Overview
Inside every smartphone, electric vehicle, and 5G base station are thousands of Multi-Layer Ceramic Capacitors (MLCCs). These tiny components are built by stacking hundreds of microscopic layers of ceramic dielectric material. During this highly delicate manufacturing process, the carrier film plays a make-or-break role. The MLCC Release Film must perfectly support the ultra-thin ceramic slurry during the casting process, and then release it flawlessly without causing any structural damage or contamination.
Key Performance Factors for MLCC Manufacturing
Achieving a high yield in MLCC production requires a release film with extreme precision. Our films are engineered to meet these exacting standards:
- Ultra-Light and Uniform Peel Force: The slurry is incredibly fragile. The film must possess a highly controlled, ultra-light release force to ensure the ceramic sheet is transferred without stretching or tearing.
- Zero Silicone Transfer: Any microscopic transfer of silicone to the ceramic layer can alter its electrical properties and ruin the capacitor. We employ strict thermal curing to guarantee 100 percent anchoring of the silicone layer.
- Exceptional Surface Flatness: The film must be perfectly smooth (typically with ultra-low roughness). Any bumps or defects will replicate onto the ceramic layer, leading to structural failures in the stacked capacitor.
- High Cleanliness: Manufactured in strict cleanroom environments to prevent dust or particulate contamination, ensuring maximum dielectric integrity.
Applications Across Industries
Our MLCC Release Film is essential for advanced electronic component manufacturing:
- MLCC Casting: Serving as the reliable carrier for green ceramic tapes during the doctor blade casting process.
- LTCC (Low-Temperature Co-Fired Ceramics): Providing stable release for complex multilayer circuit boards.
- Flexible Printed Circuits (FPC): Used as a protective and carrier film in precision circuit manufacturing.
