Thin film and laminated board for electronic board, and electronic board comprising thin film and laminated board

The film for an electronic board according to an embodiment has a moisture absorption rate of less than 0.3% with respect to an initial weight when immersed in water for 24 hours, and thus is less susceptible to a dimensional change or degradation of electrical characteristics due to a change in temperature and humidity compared to an existing film for an electronic board. Further, the film for an electronic board is comparable to or better than an existing film in terms of flexibility and physicochemical properties, and thus can be used for manufacturing a laminate having a conductive film, such as an FCCL, and an electronic board, such as an FPCB, to improve processability, durability, transmission capability, and the like. 根据实施例的用于电子板的薄膜在浸入水中24小时时，其相对于初始重量的吸湿率小于0.3％，因此与用于电子板的现有薄膜相比，其不易受到由于根据温度和湿度的变化而引起的尺寸变化或电学特性的退化。此外，用于电子板的薄膜在柔韧性和物理化学特性方面与现有薄膜相当或更优，因此可用于制造如FCCL具有导电薄膜的层压板和如FPCB的电子板，以提高可加工性、耐久性、传输能力等。
