Abstract
The utility model discloses a multilayer flexible printed circuit board and belongs to the technical field of circuit board technology. The multi-layer flexible printed circuit board includes single-side flexible printed circuit boards in multiple layers and reinforcing boards. The reinforcing boards arranged in an equally space manner are arranged between the adjacent single-side flexible printed circuit boards. The reinforcing boards are fixed between the single-side flexible printed circuit boards through insulating adhesive. The multilayer flexible printed circuit board is reasonable in structural design and simple and practical in use. The reinforcing boards are provided with through holes, so that mutual connection of the single-side flexible printed circuit boards is realized; using efficiency of the single-side flexible printed circuit boards is improved; a condition of poor circuit contact of the connection holes caused by circuit board bending is prevented effectively; and application range of the flexible printed circuit board is enlarged. At the same time, by riveting hollow copper pins in the through holes, an effect of electroplating is achieved and ventilation and heat dissipation performance is improved. Technical process is simplified, manufacturing material is reduced and cost is lowered.
Description
Technical field
The utility model relates to printed circuit field, relates in particular to a kind of multi-layer flexible printed circuit board.
Background technology
The multi-layer flexible printed circuit board of existing design, usually because multi-layer bonded being integral, in flexion area circuit frangibility, losing circuit function and the application of two-sided or multi-layer flexible printed circuit board is restricted.Conductive layer between multilayer circuit board will be communicated with simultaneously, prior art adopts the through hole that first runs through connection circuit on circuit board conventionally, through hole is again by electroplating, the upper and lower circuit of circuit board is electrically connected to, and electroplate on manufacturing, comparatively trouble is inconvenient, its manufacturing cost also increases, circuit board in use, if repeatedly bending easily causes connection hole circuit loose contact.
Utility model content
The technical problem that the utility model solves is to overcome the deficiencies in the prior art, utilization arranges through hole and in through hole, stiffener is set on multi-layer flexible printed circuit board, improve the number of bends of multi-layer flexible printed circuit board, expand range of application and the field of flexible printed circuit board, realize circuit board interconnecting between layers.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of multi-layer flexible printed circuit board, comprise Multilayer single flexible printed circuit board and stiffener, between described adjacent single-sided flexible printed circuit board (PCB), be provided with the stiffener of a plurality of equidistant arrangements, this stiffener is fixed between single-sided flexible layer printed circuit board and layer by insulating cement;
On described stiffener, through hole is set;
In described through hole, rivet columniform hollow copper pin;
Described stiffener is epoxy resin board.
Beneficial effect:
The utility model reasonable in design, simple and practical, on the stiffener of circuit board, through hole is set, realized Multilayer single flexible printed circuit board interconnecting between layers, improved the service efficiency of multi-layer flexible printed circuit board, and the mechanical strength on stiffener is stronger, has effectively prevented the situation of the connection hole circuit loose contact that circuit board causes when bending, improve the number of bends of multi-layer flexible printed circuit board, expand range of application and the field of flexible printed circuit board.Meanwhile, in through hole, rivet hollow copper pin and not only substituted the effect of electroplating, and improved the result of ventilating heat dissipation of circuit board, simplified technological process, save and make material, reduced cost.
Accompanying drawing explanation
Fig. 1 is cross-sectional view of the present utility model;
4-through hole 5-hollow copper pin in 1-circuit board 2-stiffener 3-space in figure
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is further described in detail.
A kind of multi-layer flexible printed circuit board, comprise Multilayer single flexible printed circuit board 1 and stiffener 2, the stiffener 2 that is provided with a plurality of equidistant arrangements between described adjacent single-sided flexible printed circuit board (PCB) 1, this stiffener 2 is fixed on single-sided flexible printed circuit board (PCB) 1 between layers by insulating cement;
On described stiffener 2, through hole 4 is set;
In described through hole 4, rivet columniform hollow copper pin 5;
Described stiffener 2 is epoxy resin board.
Certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned giving an example, and the variation that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection range of the present utility model.
