Abstract
The utility model discloses a FPC golden finger, including a set of golden finger pin foot (2) of locating FPC (1) connection zone, its characterized in that, the outer end of every pin foot of golden finger is the semicircle, the inner straightway of middle part for being used for walking the line of every pin foot, and the inner both sides of every pin foot are equipped with respectively along the arc chamfer of pin foot medium line symmetry, setting the shape of golden finger pin foot to outer end and being half -circular arc, the inner has arc chamfer, and according to the hydrodynamics principle, soldering tin can flow along semicircle and arc chamfer's border when the welding to when pulling out the bonding tool, soldering tin can stop on the top of circular arc, is difficult to the diffusion, can reduce even tin phenomenon, in addition, the circular arc also helps increasing the adsorption efficiency of soldering tin, thereby improve FPC's welding quality, meanwhile, owing to reduced even tin, also saved the follow -up time of scraping the tin process.
Description
Technical field
The utility model relates to a kind of FPC golden finger.
Background technology
FPC is also known as flexible circuit board, it is the abbreviation of FlexiblePrintedCircuit, adopt the printed circuit board (PCB) that flexible insulating substrate is made, have degree of crook high, walk the features such as line density is higher, thickness is thin, quality is little, scene difference according to application can suitably design, and is widely used in electronic product.By the binding region be made up of the flavous conductive contact blade of numerous neat arrangements on FPC plate, look like golden finger, therefore be referred to as in industry " golden finger ".And along with the Pin pin growing number of golden finger many, at limited FPC join domain, interval between the width of golden finger Pin pin and Pin pin is more and more less, this just causes when welding, occur between golden finger Pin pin connecting tin phenomenon, too increase the difficulty of operation simultaneously, cause product quality not high low with production efficiency.
Utility model content
The purpose of this utility model is to provide a kind of FPC golden finger, and this FPC golden finger can be avoided occurring when welding connecting tin phenomenon, improves welding quality and the efficiency of FPC.
The utility model solves the technical scheme that its technical problem adopts:
A kind of FPC golden finger, comprise the golden finger Pin pin that is mounted on FPC join domain, the outer end of each Pin pin of described golden finger is semi arch, and the middle part of each Pin pin the inner is the straightway for cabling, and the both sides of each Pin pin the inner are respectively equipped with the arc angling along Pin pin mid line symmetry.
Further, the mid line distance of adjacent golden finger Pin pin is less than or equal to the twice of single golden finger Pin pin width; The spacing of adjacent golden finger Pin pin is the width that the mid line distance of adjacent golden finger Pin pin deducts single golden finger Pin pin.
Further, the mid line distance of adjacent golden finger Pin pin is 0.5mm, and the spacing of adjacent golden finger Pin pin is 0.2mm, and the length of described straightway is 0.2mm, and the radius of described semi arch is 0.15mm, and the chamfer radius of described arc angling is 0.05mm.
The beneficial effects of the utility model are, it is semicircular arc that the shape of golden finger Pin pin is arranged to outer end, inner with arc angling, according to fluid mechanics principle, when welding, scolding tin can flow along the edge of semi arch and arc angling, and when pulling out soldering tip, scolding tin can stop on the top of circular arc, be not easy diffusion, can reduce and connect tin phenomenon; In addition, circular arc also contributes to the adsorption capacity increasing scolding tin; Thus improve the welding quality of FPC, meanwhile, due to the company's of decreasing tin, also save the time of follow-up tin scraping operation.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model provides a kind of FPC golden finger, comprise the golden finger Pin pin 2 that is mounted on FPC1 join domain, the outer end of each Pin pin of described golden finger is semi arch, the middle part of each Pin pin the inner is the straightway for cabling, and the both sides of each Pin pin the inner are respectively equipped with the arc angling along Pin pin mid line symmetry; The mid line distance E of adjacent golden finger Pin pin is less than or equal to the twice of single golden finger Pin pin width A; The space D of adjacent golden finger Pin pin is the width A that the mid line distance E of adjacent golden finger Pin pin deducts single golden finger Pin pin; Preferably, the mid line distance E of adjacent golden finger Pin pin is 0.5mm, and the space D of adjacent golden finger Pin pin is 0.2mm, and the length C of described straightway is 0.2mm, and the radius R b of described semi arch is 0.15mm, and the chamfer radius Ra of described arc angling is 0.05mm.
It is semicircular arc that the shape of golden finger Pin pin is arranged to outer end, inner with arc angling, according to fluid mechanics principle, when welding, scolding tin can flow along the edge of semi arch and arc angling, and when pulling out soldering tip, scolding tin can stop on the top of circular arc, is not easy diffusion, can reduce and connect tin phenomenon; In addition, circular arc also contributes to the adsorption capacity increasing scolding tin; Thus improve the welding quality of FPC, meanwhile, due to the company's of decreasing tin, also save the time of follow-up tin scraping operation.
The above is only preferred embodiment of the present utility model, not does any pro forma restriction to the utility model; Any those of ordinary skill in the art, do not departing under technical solutions of the utility model ambit, the Method and Technology content of above-mentioned announcement all can be utilized to make many possible variations and modification to technical solutions of the utility model, or be revised as the Equivalent embodiments of equivalent variations.Therefore; every content not departing from technical solutions of the utility model; according to technical spirit of the present utility model to any simple modification made for any of the above embodiments, equivalent replacement, equivalence change and modification, all still belong in the scope of technical solutions of the utility model protection.
