The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

Referring to fig. 2, fig. 2 is a schematic structural diagram of a circuit board according to a first embodiment of the present application.

The first embodiment of the present application designs a circuit board, which includes a rigid circuit board 1, a flexible circuit board 2, a connector 3, and a component 4.

the component 4 is arranged on the upper surface of the rigid circuit board 1, and the flexible circuit board 2 is connected with the rigid circuit board through the connecting piece 3.

The connecting member 3 may be specifically disposed on the same side of the component 4, that is, the flexible circuit board 2 is disposed on the upper surface of the rigid circuit board 1 through the connecting member 3.

the circuit board that this application embodiment provided connects rigid circuit board 1 and flexible circuit board 2 through setting up the connecting piece, compares in the structure of pressing from both sides flexible circuit board 2 in the centre through two rigid circuit board 1 among the prior art, has saved a rigid circuit board 1, the cost is reduced.

On the basis of the first embodiment described above, in order to further save space, the present application provides the following second embodiment.

Referring to fig. 3, fig. 3 is a schematic structural diagram of a circuit board according to a second embodiment of the present application.

In this embodiment, the connecting member 3 is specifically a conductive adhesive, and more specifically, an anisotropic conductive adhesive. The anisotropic conductive adhesive is a semitransparent conductive double-sided adhesive and consists of a double-sided adhesive base material and a conductive gold ball.

The upper surface of the flexible circuit board 2 is connected with the lower surface of the rigid circuit board 1 through anisotropic conductive adhesive. According to this kind of structure, the upper surface of rigid circuit board 1 need not to reserve the position that sets up connecting piece 3 again, and flexible circuit board 2 can directly set up under other components and parts 4, and need not to place side by side with components and parts 4, leads to taking more spaces.

Therefore, the structure of the circuit board provided by the second embodiment of the present application further saves space on the basis of not increasing cost.
