Abstract
The utility model discloses a kind of flexible PCB, comprise base portion, flexible joint, be connected to the first kink of the side on described flexible joint first direction, described first kink to bend downwards after 180 ° and extends to the second direction contrary with first direction; Described first kink connects the first sticker portion, and described first sticker portion is connected with welding disk; Side in the second direction of described flexible joint is connected with the second kink, extends to first direction after described second kink bends 180 ° downwards; Described second kink is connected with the second sticker portion, and described second sticker portion is connected with described base portion.The utility model structure is simple, is easy to produce, and simple installation, can effectively overcome defect of the prior art, ensures working strength and the useful life of flexible PCB.
Description
Technical field
The utility model relates to board production and manufactures field, particularly relates to a kind of flexible PCB.
Background technology
The title of circuit board has: wiring board, pcb board, aluminium base, high frequency plate, thick copper coin, impedance plate, PCB, ultra-thin wiring board, ultrathin circuit board, printing (copper lithographic technique) circuit board etc.Circuit board makes circuit miniaturization, visualize, for permanent circuit batch production and optimize electrical appliance layout and play an important role.Circuit board can be described as printed substrate or printed circuit board (PCB), and English name is (Printed Circuit Board) PCB.Circuit board is widely used in electronics field.Flexible circuit board (Flexible Printed Circuit, hereinafter referred to as FPC), is applied in each class of electronic devices, as: mobile phone, notebook computer, panel computer, hand-held game machine etc.FPC need be connected with other circuit boards or chip by the welding disk on it.FPC of the prior art adopts the shortest patten's design mostly, and namely as shown in Figure 1, flexible joint 100 length in the X direction of FPC is shorter, welding disk 200 be arranged on described flexible joint along the end in described X-direction.The FPC of existing structure, when the flexible joint 100 of FPC bends, the Y position of welding disk 200 can be subject to very large pulling force active force, and the situation of FPC pad fracture so very easily occurs.
Utility model content
Therefore, the technical problems to be solved in the utility model overcomes defect of the prior art, provides a kind of flexible PCB that pad fracture can not easily occur.
To achieve these goals, a kind of flexible PCB of the present utility model, comprise base portion, flexible joint, be connected to the first kink of the side on described flexible joint first direction, described first kink to bend downwards after 180 ° and extends to the second direction contrary with first direction; Described first kink connects the first sticker portion, and described first sticker portion is connected with welding disk; Side in the second direction of described flexible joint is connected with the second kink, extends to first direction after described second kink bends 180 ° downwards; Described second kink is connected with the second sticker portion, and described second sticker portion is connected with described base portion.
The side that described first sticker portion is positioned on the perpendicular third direction of second direction is connected with welding disk.
The side that described second sticker portion is positioned in the contrary fourth direction of third direction is connected with base portion.
Adopt technique scheme, flexible PCB of the present utility model, the flexible joint be connected with base portion can carry out flexible bending and stretch, and the pulling force effect that the kink be connected with described flexible joint will overcome welding disk root, thus avoid the situation that FPC pad ruptures.The utility model structure is simple, is easy to produce, and simple installation, can effectively overcome defect of the prior art, ensures working strength and the useful life of flexible PCB.
Accompanying drawing explanation
Fig. 1 is the structural representation of flexible PCB in prior art.
Fig. 2 is the utility model structural representation.
Fig. 3 is the structural representation of another angle of the utility model.
Embodiment
Below by way of the drawings and specific embodiments, the utility model is described in further detail.
The present embodiment provides a kind of flexible PCB, as shown in Figure 2,3, comprise base portion 1, flexible joint 2, be connected to the first kink 31 of the side on described flexible joint 2 first direction A, extend to the second direction B contrary with first direction A after described first kink 31 bends 180 ° downwards; Described first kink 31 connects the first sticker portion 51, and described first sticker portion 51 is connected with welding disk 4; Side on the second direction B of described flexible joint 31 is connected with the second kink 32, extends to first direction A after described second kink 32 bends 180 ° downwards; Described second kink 32 is connected with the second sticker portion 52, and described second sticker portion 52 is connected with described base portion 1.
The side that described first sticker portion 51 is positioned on the perpendicular third direction C of second direction B is connected with welding disk 4.
The side that described second sticker portion 52 is positioned on the contrary fourth direction D of third direction C is connected with base portion 1.
Adopt technique scheme, flexible PCB of the present utility model, the flexible joint be connected with base portion can carry out flexible bending and stretch, and the pulling force effect that the kink be connected with described flexible joint will overcome welding disk root, thus avoid the situation that FPC pad ruptures; Circuit board can be pasted onto on electricity consumption device by sticker portion, place pad fracture further.The utility model structure is simple, is easy to produce, and simple installation, can effectively overcome defect of the prior art, ensures working strength and the useful life of flexible PCB.
Obviously, above-described embodiment is only for clearly example being described, and the restriction not to execution mode.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all execution modes.And thus the apparent change of extending out or variation be still among the protection range that the utility model creates.
