Customized 4g/In Pet Film Release Liner MLCC Manufacturing Process

4g / in MLCC PET Silicone Release Film MLCC Manufacturing Process

This product is used as a base material of high flatness, high temperature resistance PET, coated on the surface of the thin layer of release substance MLCC formulations. Mainly used in MLCC tape coating.

• Producing in the 1000-level clean environment, with high cleanness
• The coating is uniform and the film surface is flat with minimal tolerance, making the subsequent process easy to process
• High residual adhesion rate (≥85%), no performance impact on the bonding material, non-polluting
• High-Quality PET Base Film: Made from bidirectional-stretched polyester (BOPET), offering superior mechanical strength, rigidity, and tear resistance for stable handling during high-speed production
• Compliance: Meets RoHS/REACH requirements and semiconductor-grade cleanliness standards

Ceramic Layer Transfer in MLCC Production

Primary Role: Acts as a carrier substrate during the ceramic slurry casting process. The film holds the ceramic slurry in place while solvents evaporate, forming uniform ceramic green sheets.

Key Requirement: High smoothness (≤0.2μm defects) to ensure defect-free ceramic layers, critical for high-capacity MLCCs.

Multilayer Stacking & Lamination

Layer Alignment: Enables stacking of 300 -1,000 ceramic layers by maintaining alignment and preventing adhesion between layers during lamination.

Controlled Release Force: Ensures easy separation without residue, preserving the integrity of ultrathin ceramic layers (as thin as 0.025mm).
