Features
- The adoption of PET base film and polyester coating is to ensure maintenance of good performance and stability even under high-temperature conditions.
- It remains smooth and wrinkle-free under high temperatures, ensuring consistency in the packaging process and product quality.
- Ensures no residues are left behind after the peeling process, thus maintaining the cleanliness of the chips and the mold.
- For exposed molding components, such as lead frame terminals and exposed chip structures, it exhibits strong resistance to burrs.
