Flexible circuit version why not eliminate pcb hard printed circuit board
and its high density determines that it can only be on rigid printed boards. So now when you need to use the flexible board when you need a rigid part of the time, will be designed as rigid and flexible combination board.
it is necessary to ensure that the board can be bent, but also to ensure good welding device, between the two contradictory. For devices such as BGA, it is not possible to design a flexible board,
The benefit of the flexographic version is that it can be fitted to where it needs to be bent, but for flexo, its performance is affected by the number of times of bending and the environment in which it is used, and in many cases it can not be used repeatedly and can be found
