Abstract
The utility model discloses a flexible circuit board with a reinforcing structure, which comprises an insulating sheet body, an electronic part and a reinforcing element, wherein a plurality of conductive circuits and a plurality of earth points are arranged in the insulating sheet body; the two end parts of the insulating sheet body are respectively provided with a plurality of metal pins; a pin of the electronic part penetrates through one surface of the insulating sheet body and is welded on at least one conductive circuit; the reinforcing element is fixed on the other surface of the insulating sheet body and corresponds to the position of the pin of the electronic part; an opening is arranged on the insulating sheet body, is located between the earth points and the reinforcing element, and is filled with soldering tin; the reinforcing element is welded on the insulating sheet body through the surface mounting technology; and the reinforcing element and the earth points are conducted through the soldering tin. As the surface mounting technology is adopted to mount the reinforcing element on the flexible circuit board, the operating time can be shortened and the processing efficiency can be improved; moreover, the flexible circuit board with the reinforcing structure has the advantages of higher reliability, low cost and better bonding effect.
Description
Technical field
The utility model belongs to the manufacturing technology field of flexible circuit board, particularly a kind of flexible circuit board that has the steel disc reinforced structure in the end that is electrically connected pin.
Background technology
Flexible circuit board is generally used for connecting two electronic installations, the signal of telecommunication is linked to each other, usually flexible circuit board all is made by membrane material, therefore thinner thickness is also very soft, therefore with electronic component (as resistance, when electric capacity etc.) being welded on the flexible circuit board, be easy to make flexible circuit board that bending and distortion take place, therefore often need be at the back side of flexible circuit board, it is the material that the other side of the weld zone of electronic component is sticked on steel disc or other inflexibles, this steel disc simultaneously also with the earth terminal conducting of flexible circuit board, play the effect of ground connection and electromagnetic shielding, as Chinese patent 200820155594.3; Sometimes, this steel disc also can be mounted on the earthing position place on the flexible circuit board separately under the situation that does not need mounted with electronic components, play the effect of ground connection and electromagnetic shielding.
Yet in the prior art, steel disc all is to be attached on the leads ends of flexible circuit board by conducting resinl, the course of processing is: the pin place that at first conducting resinl is attached to flexible circuit board, then steel disc is placed on the conducting resinl, carry out pressing by equipment again, at last flexible circuit board is put into the baking oven baking and taken out after 2.5 hours.Except that conducting resinl drawback with high costs, this mode also has the shortcoming that the activity duration is long, power consumption is many.This mode also has a drawback to be: only can the smooth steel disc of machining shape, and the steel disc of, surface irregularity special for some shapes can't pressing and processing, therefore has certain limitation.
Summary of the invention
The purpose of this utility model provides a kind of flexible circuit board with reinforced structure, and it does not utilize conducting resinl just supporting material can be combined on the flexible circuit board.
For achieving the above object, the technical solution adopted in the utility model is: a kind of flexible circuit board with reinforced structure, it comprises: the insulation lamellar body, be laid with many conducting wires and a plurality of earth point in the described insulation lamellar body, the both ends of described insulation lamellar body have a plurality of metal pins respectively; Reinforcement element, the constituent material of described reinforcement element are metal material, and described reinforcement element is fixed on the side surface of described insulation lamellar body; Has opening on the described insulation lamellar body, described opening is between described earth point and described reinforcement element, be filled with scolding tin in the described opening, and described reinforcement element is welded on the described insulation lamellar body by surface mounting technology, is conducted by scolding tin between described reinforcement element and the described earth point.
Preferably, the constituent material of described reinforcement element is stainless steel or aluminium.
Preferably, the material of described scolding tin is a lead-free solder.
Further, the material of described scolding tin is the SAC scolder.
Because technique scheme utilization, the utility model compared with prior art has following advantage: since adopt in the utility model surface mounting technology with the reinforcement component mounter on flexible circuit board, just can finish processing about 6 minutes, can shorten the activity duration, improve working (machining) efficiency; In addition, it is higher to adopt surface mounting technology also to have reliability, follow the advantage of better effects if, and the conductivity of scolding tin is better than conducting resinl, and price is cheaper, has therefore more saved material cost, has saved power consumption, accomplishes energy-saving and emission-reduction.
