This FPC release film serves as a covering film during flexible printed circuit board lamination processes. It provides functional isolation and separation capabilities, and is also utilized for false bonding and compression of EML and FR4 materials.
Three-layer construction consisting of release layer, high-temperature resistant PET substrate, and release layer for optimal performance in demanding manufacturing environments.
- Double matte surfaces for easier production handling and operation
- Minimal surface static electricity prevents dust and foreign object adsorption
- Low silicone oil transfer minimizes contamination risks during FPC manufacturing
