Abstract
The utility model provides a high-reliability hard and soft combined board. The hard and soft combined board comprises a first hard board, a second hard board and a soft board which is positioned between the first hard board and the second hard board, wherein a first covering film is arranged at the center of the upper surface of the soft board, the first hard board is pressed on the first covering film through a first prepreg, a second covering film is arranged at the center of the lower surface of the soft board, and the second hard board is pressed on the second covering film through a second prepreg. According to the hard and soft combined board, through windowing of the prepregs, the covering films are attached to the soft board corresponding to the windowing positions, extra combination of the covering films with the immobile prepregs is effectively avoided, so that the hard boards and the soft board are pressed through the immobile prepregs except the windowing positions, the binding force between the soft board and the hard boards is improved, the problems of board explosion and layering are solved, and the reliability of products is improved.

Rigid Flex is by filmated flexible bottom and rigid bottom combination, then is laminated in a single component, the circuit board of formation, and it has rigid layer and flexible layers concurrently, is a kind of multilayer board.In the PCB industry, Rigid Flex is the very fast class printed board of growth in recent years, and growth rate is fast, and application is wide.
But current Rigid Flex, because the coverlay in hardboard zone is poor with the adhesion of the prepreg that do not flow, the problem of layering plate bursting easily occurs, and product reliability is poor.
The utility model content
For this reason, the purpose of this utility model is to provide a kind of Rigid Flex of high reliability, the problem of layering plate bursting easily occurs to solve current Rigid Flex.
The purpose of this utility model is achieved through the following technical solutions.
A kind of high reliability Rigid Flex, comprise the first hardboard (1), the second hardboard (2) and be positioned at the soft board (5) between the first hardboard (1), the second hardboard (2), described soft board (5) upper surface center is provided with the first coverlay (6), and described the first hardboard (1) is pressed together on the first coverlay (6) by the first prepreg (3); Described soft board (5) lower surface center is provided with the second coverlay (7), and described the second hardboard (2) is pressed together on the second coverlay (7) by the second prepreg (4).
Preferably, be provided with the 3rd window (301) on described the first prepreg (3), on the first hardboard (1), be provided with and the 3rd first window (101) that window (301) size is identical and position is corresponding, described the first coverlay (6) is positioned under first window (101), the 3rd window (301), and its outward flange compresses by the first prepreg (3).
Preferably, be provided with four-light mouth (401) on described the second prepreg (4), be provided with Second Window (201) identical with four-light mouth (401) size and that position is corresponding on the second hardboard (2), described the second coverlay (7) be positioned at four-light mouth (401), Second Window (201) under, and its outward flange compresses by the second prepreg (4).
The utility model compared with prior art, beneficial effect is: the Rigid Flex of the high reliability that the utility model provides, by prepreg is windowed, the coverlay correspondence is fitted on the soft board corresponding with the position of windowing, effectively avoided the too much combination of coverlay with the prepreg that do not flow, make hardboard and soft board except other zones beyond window position all by mobile semi-solid preparation pressing, thereby improved the adhesion of rigid-flex, avoid the problem of plate bursting and layering, improved the reliability of product.
