Abstract:
The present disclosure relates to a printed circuit board, a display device including the same, and a manufacturing method therefor. The printed circuit board includes a rigid region; and a flexible region comprising a flexible layer having a first surface and a second surface on an opposite side to the first surface, a reinforcing structure disposed on the first surface of the flexible layer, and a conductor pattern disposed on the second surface of the flexible layer. A material of the reinforcing structure has a coefficient of thermal expansion lower than that of a material of the flexible layer.
Abstract:
A method of manufacturing a rigid-flexible printed circuit board, which including: providing a first flexible film having a first metal layer on one or both surfaces; forming a circuit pattern by patterning the first metal layer; forming a second flexible film, which has a second metal layer on one surface, on one or both surfaces of the first flexible film; forming a circuit pattern by patterning the second metal layer in a rigid domain R; providing an anti-oxidation protective layer on the second metal layer in a flexible domain F; laminating at least one circuit layer on the second flexible film; and removing the circuit layer in the flexible domain F.
Abstract:
The present invention relates to a method of manufacturing a flying tail type rigid-flexible printed circuit board and a flying tail type rigid-flexible printed circuit board manufactured by the same and implement a flying tail type rigid-flexible printed circuit board with improved filling property by providing a method of manufacturing a flying tail type rigid-flexible printed circuit board including: providing a base substrate having a first inner circuit pattern layer on both surfaces; laminating a first insulating layer on a rigid domain R of the base substrate; laminating at least one circuit layer, which extends over the entire domain of the base substrate, on the first insulating layer; and removing a portion of the circuit layer, which corresponds to a flexible domain F, wherein the circuit layer includes a second insulating layer and a flying tail type rigid-flexible printed circuit board manufactured by the same.
