Description

A kind of flexible PCB

Technical field

The utility model is related to a kind of circuit boards, and in particular to a kind of flexible PCB.

Background technology

At present, the structure that COMPLEX MIXED IC interior directly carries out short-circuit interconnection is mostly separate conductors, works as number of lead wires When measuring more, it is difficult to control cabling consistency, can also increase the adhesives dosage of anchor leg；Not only influence circuit internal junction The consistency of structure, and it is difficult to control harmful atmosphere content inside sealing structure circuit；If made using conventional soft arranging wire For short-circuit interconnection architecture, when span is larger and needs along labyrinth surface cabling, soft arranging wire is difficult to fix, and can not divide It uses, poor universality.

Utility model content

The purpose of this utility model is to provide a kind of flexible PCBs, can not only realize COMPLEX MIXED integrated circuit plate Electrical interconnection function, make cabling consistency carefully controlled, and facilitate fixation that flexible cord arranges and by hand to neat point of circuit board It cuts.

To achieve the above object, the utility model employs following technical scheme：

A kind of flexible PCB, including plate body, the plate body includes the first insulating film and the second insulating film that are stacked, Multiple plain conductors are arranged in parallel between first insulating film and the second insulating film, are equipped between neighboring metallic wires more A through-hole, the edge of the through-hole connect with the plain conductor of its both sides and in matrix arrangement, the both ends of the plain conductor A conductive tabs are connected separately with, the conductive tabs extend to electric connecting terminal of the outside as circuit board of plate body.

As a further improvement of the above technical scheme：

The width of the conductive tabs is more than the width of plain conductor, and the first insulation is fixed in wherein one end of conductive tabs Between film and the second insulating film.

The conductive tabs weld, be bonded or crimping by way of be fixedly connected with plain conductor.

The conductive tabs surface is coated with nickel billon.

The plain conductor and conductive tabs are manufactured using copper material.

The plain conductor is fixed on by hot pressing mode between the first insulating film and the second insulating film.

The thickness of the plain conductor is 15~30 ounces.

The width of the connecting pin of the conductive tabs and plain conductor is more than the width of its other end.

As shown from the above technical solution, flexible PCB described in the utility model can not only realize COMPLEX MIXED collection Into the electrical interconnection function of circuit board, and cabling consistency is carefully controlled, arbitrary surfaces that can be in labyrinth, any position Dispensing is carried out to fix, it can not also be by tool, using craft along through-hole by the neat Ground Split of flexible PCB.It is enough effectively to solve The problem of existing short circuit interconnection architecture cabling consistency is poor, poor universality makes the short-circuit interconnection architecture of COMPLEX MIXED integrated circuit Consistency improves, and cabling mode is more flexible.

Description of the drawings

Fig. 1 is the structure diagram of the utility model.

Specific embodiment

The utility model is described further below in conjunction with the accompanying drawings：

As shown in Figure 1, the flexible PCB of the present embodiment, including plate body 1, plate body 1 includes the be stacked first insulation Film and the second insulating film are arranged in parallel with multiple plain conductors 2 between the first insulating film and the second insulating film, adjacent metal is led Multiple through-holes 3 are equipped between line 2, the edge of through-hole 3 connect with the plain conductor 2 of its both sides and in matrix arrangement, and metal is led The both ends of line 2 are connected separately with a conductive tabs 4, and conductive tabs 4 extend to electrical connection of the outside as circuit board of plate body 1 End.

In order to improve the fatigue resistance of circuit board, in the present embodiment, the width of conductive tabs 4 is set greater than metal The width of conducting wire 2, specific size is depending on actual conditions；The first insulating film and are fixed in wherein one end of conductive tabs 4 Between two insulating films, so that conductive tabs 4 preferably can connect fixation with plain conductor 2.By the plain conductor 2 connected and Conductive tabs 4 are fixed on by hot pressing mode between the first insulating film and the second insulating film.

Further, conductive tabs 4 can weld, be bonded or crimping by way of be fixedly connected with plain conductor 2.In conduction 4 surface of tap is coated with nickel billon.Conductive adhesive and crimping may be used in connection using the conductive tabs 4 that plating nickel gold closes Technique is assembled, and the technique of welding can also be used to be assembled, be made assembling more convenient, and gold is not oxidizable, can be with It plays a protective role to copper strips.

The present embodiment, plain conductor 2 and conductive tabs 4 are manufactured using copper material.The thickness of plain conductor 2 for 15~ 30 ounces, the thickness of the present embodiment plain conductor 2 is preferable over 15 ounces, 30 ounces or 20 ounces.In order to facilitate conductive tabs 4 with The connection of other circuits and the shock resistance for improving circuit board, by width of the conductive tabs 4 in the connecting pin with plain conductor 2 It is designed as the width more than its other end.

The spot printing bonded adhesives at through-hole 3, can make flexible circuit version fit perfectly on the surface of labyrinth.Through-hole 3 is not only It can realize the electrical interconnection function of COMPLEX MIXED integrated circuit plate, make cabling consistency carefully controlled, and can be in labyrinth Arbitrary surfaces, any position carry out dispensing and fix, be alternatively arranged as the cut-off rule that flexible PCB is partly or wholly divided, can be with Not by tool, it is split using by hand.

Embodiment described above is only that the preferred embodiment of the utility model is described, not to this practicality Novel range is defined, and under the premise of the spirit of the design of the utility model is not departed from, those of ordinary skill in the art are to this The various modifications and improvement that the technical solution of utility model is made should all fall into the protection that the utility model claims book determines In the range of.
