与刚性板相比，挠性板最大的特点便是其柔软性。然而这一优点也决定了制作的难度。制作挠性板的覆铜软板和覆盖膜都是挠性的，因此其制作工艺比刚性板更复杂，对同样的最小线宽，最小线距和最小焊盘，挠性板的制作难度要大得多。有些设计者有意无意地追求细小的线宽、线距和严 Compared with the rigid board, the biggest feature of the flexible board is its softness. However, this advantage also determines the difficulty of making. The production of flexible copper clad flexible board and the cover film are flexible, so the production process is more complex than the rigid board, the same minimum line width, minimum line spacing and minimum pad, the difficulty of making the flexible board to Much bigger. Some designers consciously or unconsciously pursue small line width, line spacing and strict
