Common factors and attention problems of fluorine release film-technical knowledge
Common factors of fluorine release film and the source of attention: protective film factory direct release time: 2019-05-31 click: 1751 1. The cleanliness of the release film, cleanliness is currently restricting high-quality fluorine release film , An important factor in whether it can be widely used in HDI production; therefore, manufacturers or suppliers of durable fluorine release films must operate in a clean room when coating, winding and cutting release films. The clean room must reach level 10,000 to ensure the surface cleanliness of the release film, so as to ensure the quality of the board surface after RCC compression. 2. Pay attention to distinguish the front and back of the single-sided release film. Since the single-sided fluorine release film has only one side of the release and the other side is the PET substrate surface, if the release film is used on the wrong side, it will cause the lower board after pressing. When the film sticks to the board surface, it is difficult to tear off. There are the following methods to distinguish the front and back: a. Use adhesive paper to stick the fluorine release film surface. If it can be stuck, it is the PET substrate surface, and the non-stick surface is the release surface; b. The reverse side mark distinguishes the front and the back. 3. The surface of the release film has static electricity. If the release film has too much static electricity, the film surface will easily adhere to dust particles, which will affect the quality of the board; the same reason, in order to reduce the static electricity of the release film, the release film is wound in the coating And when cutting, special treatment should be done for static electricity. In addition, you should also pay attention to the temperature of the pressure plate of the PET release film. The material temperature is lower than the temperature of the platen table, because the current temperature of the fluorine release film is about 200 degrees Celsius. If the temperature of the platen table exceeds this degree Celsius, the fluorine is released The type film will undergo aging and brittleness, and there may be problems with sticking or contaminating the surface of the board. The above precautions can effectively avoid the occurrence of various common problems. Foshan Bowei Environmental Protection Material Co., Ltd. is an electronic material supplier with 10 experiences, which can produce PET film with multiple functions, such as: sub-(matte) surface PET film, flame-retardant (fireproof) PET film, inkjet printing film , Anti-static PET film, anti-fog PET film, anti-UV PET film, non-shrinking PET film, PET release film, etc. Interested parties welcome to inquire!
