1. The cleanliness of release membranes is currently an important factor that restricts the widespread use of high-quality fluorine release membranes in HDI production; Therefore, manufacturers or suppliers of durable fluorine release films must work in clean rooms when coating, winding, and cutting release films. The clean room must reach a level of 10000 to ensure the surface cleanliness of the release film, thereby ensuring the quality of the RCC pressed board.
2. Pay attention to distinguishing between the front and back sides of the single sided release film. As the single sided fluorine release film only has one side for release and the other side is the PET substrate surface, if the release film is used on the wrong side, it will cause the film to stick to the board surface after pressing, making it difficult to tear it off. There are the following methods to distinguish the front and back: 1. Use adhesive paper to stick the fluorine release film surface. If it can be adhered, it is the PET substrate surface, and the non adhered surface is the release surface; 2. Mark the front and back of the film to distinguish between the front and back.
