Abstract
An arc gap is set at the connection portion between gold finger of flexible printed circuit (FPC) and PCB. The arc gap is axial symmetry in relation to the gold finger. With the setting of arc gap, the solder can flow in the gap to make the edge of gold finger more firmly. The arc gap can also absorb solder to make solder not capable of diffusing that will cause the interconnection of solder.
Description
Technical field
The present invention relates to a kind of FPC golden finger.
Background technology
Increase along with FPC golden finger quantity, size at FPC has under the prerequisite of qualification, the width of golden finger can only reduce with gap each other, like this when welding FPC and PCB, connect tin etc. between the FPC golden finger, failure welding rolls up, and welding efficiency is low, thereby has a strong impact on the welding quality of FPC and PCB.
Summary of the invention
Purpose of the present invention is exactly in order to overcome the above problems, and a kind of FPC golden finger is provided.
For achieving the above object, the present invention proposes a kind of FPC golden finger, sets the camber line breach at the terminal that FPC golden finger and PCB join.
Described camber line breach is with respect to the axis symmetry of golden finger.
Described camber line breach is semicircle.
After being provided with the camber line breach, according to hydromechanical principle, scolding tin can flow in breach, when such scolding tin connects, connect more firmly at the golden finger edge, breach can also adsorb scolding tin, reason owing to adhesive force, scolding tin is not easy diffusion, the situation of tin so just can not occur connecting, thereby improves the welding quality of FPC and PCB greatly.
The camber line breach be shaped as semicircle, the semicircle camber line is flowing of the most suitable liquid, the tension force maximum, the effect of absorption scolding tin is best.
Description of drawings
Also the present invention is described in further detail in conjunction with the accompanying drawings below by specific embodiment.
Fig. 1 is a structural representation of the present invention.
Embodiment
A kind of FPC golden finger, as shown in Figure 1, after the terminal that FPC golden finger and PCB join is set camber line breach 1, is provided with camber line breach 1, according to hydromechanical principle, scolding tin can flow in breach, when such scolding tin connects, connects more firmly at the golden finger edge, breach can also adsorb scolding tin, because adhesive force, scolding tin are not easy diffusion, the situation of tin so just can not appear connecting.Camber line breach 1 is with respect to the axis symmetry of golden finger, in the present embodiment, the camber line breach 1 of FPC golden finger be shaped as semicircle, the semicircle camber line is flowing of the most suitable liquid, the tension force maximum, the effect of absorption scolding tin is best.
Claims (3)
1, a kind of FPC golden finger is characterized in that: set camber line breach (1) at the terminal that FPC golden finger and PCB join.
2, FPC golden finger according to claim 1 is characterized in that: described camber line breach (1) is with respect to the axis symmetry of golden finger.
3, FPC golden finger according to claim 1 and 2 is characterized in that: described camber line breach (1) is for semicircle.
