[0026] In order to illustrate the idea and purpose of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0027] The present invention provides a rigid-flex board and its manufacturing method. It mainly opens windows of different sizes on the two layers of prepreg between the soft and hard boards, and the soft board covering film is located in the above-mentioned windows, and Overlap and press one of them to achieve the purpose of increasing the support strength and avoiding the breakage of the soft board, while ensuring the bonding effect of the soft board cover film and the curing sheet; improving the flatness of the rigid-flex joint of the circuit board.
[0028] Such as figure 2 as shown, figure 2 It is a structural schematic diagram of the rigid-flex board of the present invention. A rigid-flex board according to the present invention includes a hard board 201 and a soft...
