Abstract

The invention relates to the technical field of communication, in particular to a printed circuit board and a manufacturing method thereof. The printed circuit board comprises a first circuit board enabling a flexibility parameter after etching to serve as a first parameter and a second circuit board enabling a flexibility parameter after etching to serve as a second parameter. The manufacturing method comprises the steps of respectively performing etching on the first circuit board and the second circuit board according to a preset circuit pattern; and enabling the etched first circuit board to be connected with the etched second circuit board. According to the printed circuit board, the manufacturing method of the printed circuit board and an electronic device, the first circuit board and the second circuit board are respectively cut into corresponding shapes according to the preset circuit pattern after undergoing press fit, and the cut first circuit board and the cut second circuit board are connected. Due to the fact that the formed circuit board has a certain elasticity, the anti-breaking capability is high; besides, the formed circuit board can be bent randomly, and diversification of electronic product forms is facilitated. In addition, the cost of the formed circuit board is lower than that of the first circuit board, and device adhesion to two sides can be achieved.

Description

technical field [0001] The invention relates to the technology in the communication field, in particular to a printed circuit board, a manufacturing method thereof, and an electronic device. Background technique [0002] At present, the material of most PCB (Printed Circuit Board, printed circuit board) boards is hard and the shape is fixed. However, its drop resistance is poor, so due to the lack of elasticity, the components soldered on the PCB may be desoldered due to falling. Moreover, it has planar restrictions on the structural design of the system. For example, the external interfaces soldered on the PCB board must be based on the PCB. [0003] In order to make the PCB no longer rigid, a pure FPC (Flexible Printed Circuitboard, flexible printed circuit board) design is proposed in the prior art. However, where the device needs to be welded on the FPC, a rigid "reinforcing board" needs to be attached to the FPC on the other side of the device where the device is weld...
