Product Description
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.
Product Features
- 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
- Precision for Miniaturized MLCCs: Supports ultra-thin ceramic layers (down to 1 μm) required for 300-1,000-layer capacitors in 5G and automotive electronics
Product Structure
Product Use
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.
Product Packaging
- Products are generally used by cardboard tray, nude tray packaging
- All cartons of products have certificate, packing list, each tray should have a list of products
- Our products can also be packaged according to the requirements of the user agreement
