Abstract
The utility model discloses a pad structure of a flexible circuit board and relates to the flexible circuit board, in particular to a pad of the flexible circuit board. The pad structure comprises the flexible circuit board, a plurality of three-dimensional pads and a plurality of three-dimensional LED (light emitting diode) pins, wherein each three-dimensional pad comprises a long edge and a short edge; the plurality of pads are uniformly arranged into a row along the long edges of the pads and are arranged on the flexible circuit board; each three-dimensional LED pin comprises a long edge and a short edge, and each LED pin is spanned and bonded onto two pads and fixed on the flexible circuit board along the long edge of the LED pin; and the short edge of each LED pin is wider than that of each pad. The pad structure has the beneficial effects that the short edge of each LED pin is wider than that of each pad, so that the LED pins cannot slide and shift due to the big pads in mount of LEDs; and the assembled LEDs are positioned on the same straight line in one plane, thereby ensuring the illumination effect of the product and improving the yield rate of the product.
Description
Technical field
The utility model relates to Flexible Printed Circuit, relates in particular to the pad of Flexible Printed Circuit.
Background technology
At present, the pad that Flexible Printed Circuit is used to install LED is all bigger, no matter be chip mounter or manual lighting a lamp, still can cause moving of LED when crossing stove, it is crooked to form LED, make light-emitting area not on same horizontal line, because pad is bigger, and it is many tin, cause the afterbody of partial L ED to be come simultaneously by jack-up, cause the variant of illumination effect equally, even form the light beam speck.
The utility model content
The utility model is at the deficiencies in the prior art, aim to provide a kind of when mounting LED LED can not produce the pad structure of the Flexible Printed Circuit of displacement.
The utility model is achieved through the following technical solutions: a kind of pad structure of Flexible Printed Circuit, comprise the pad of Flexible Printed Circuit, some stereochemical structures and the LED pin of some stereochemical structures, the pad of stereochemical structure comprises a long limit and a minor face, and some pads are evenly arranged into a row along the pad long side direction and are arranged on the Flexible Printed Circuit; The LED pin of stereochemical structure comprises a long limit and a minor face, and each LED pin is fixed in Flexible Printed Circuit along long limit across being bonded on two pads; The minor face width of described LED pin is greater than the minor face width of pad.
Below above technical scheme is further elaborated:
LED pin minor face width is greater than pad minor face width 0.05mm.
The surface of described pad is a network structure.
The beneficial effects of the utility model are: the minor face width of one, LED pin is greater than the minor face width of pad, like this, when mounting LED, the LED pin just can not be owing to pad produces the situation of skidding with displacement greatly, the LED that mounts is on conplane same straight line, guarantee the product illumination effect, improved yield of products; Two, the surface with pad is made into network structure, has guaranteed that the Copper Foil of pad is difficult for peeling off, and has prolonged the useful life of product.
Description of drawings
Fig. 1 is the utility model pad configuration schematic diagram;
Fig. 2 is mounted on structural representation on the pad for the utility model with LED.
Among the figure, 1, Flexible Printed Circuit; 2, pad; 3, LED pin.
Embodiment
Below in conjunction with drawings and Examples the utility model is described further:
With reference to shown in Figure 1, the pad 2 of stereochemical structure comprises a long limit and a minor face, and pad 2 is evenly arranged into a row along pad 2 long side directions and is arranged on the Flexible Printed Circuit 1; With reference to shown in Figure 2, the LED pin 3 of stereochemical structure comprises a long limit and a minor face, and each LED pin 3 is fixed in Flexible Printed Circuit 1 along long limit across being bonded on two pads 2; The minor face width of LED pin 3 is greater than the minor face width of pad 2; Like this, when mounting LED, LED pin 3 just can not be owing to pad 2 produces the situation of skidding with displacement greatly, and the LED that also can guarantee to mount has guaranteed the product illumination effect on conplane same straight line, improved yield of products.The utility model is made into network structure with the surface of pad 2, has guaranteed that the Copper Foil of pad 2 is difficult for peeling off, and has prolonged the useful life of product.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also carry out suitable change and modification to above-mentioned execution mode.Therefore, the embodiment that discloses and describe above the utility model is not limited to also should fall in the protection range of claim of the present utility model modifications and changes more of the present utility model.In addition, although used some specific terms in this specification, these terms do not constitute any restriction to the utility model just for convenience of description.
