Do LED soft light with which kind of circuit board
Mainly used as electronic components of the conduction volume relative to the PCB is small, the corresponding space is small, but the price is expensive. Above is my understanding of the board, I hope to help you.
PCB is a rigid pcb (or hard) as an electronic element carrier and conduction function of the price relatively cheaper FPC FPC refers to the flexible circuit board (i.e. soft board)
It depends on what you mean by the use of a soft ribbon
PCB is a printed circuit board or printed circuit board, or printed circuit board FPC is a flexible circuit board referred to as, also known as soft board, white is a hard, one is the soft board. Soft light, then, certainly with FPC
