Abstract
The present invention discloses FPC golden fingers for improving connection strength. The middle parts of the FPC golden fingers are provided with holes. The central connecting lines of the holes form a curve. After the middle parts of the FPC golden fingers are provided with the holes, soldering tin can penetrate into the holes 1 during the point welding of the end parts of the FPC golden fingers when an FPC is welded with a PCB, and thus, the effective tin penetration of the FPC and the PCB is realized. The FPC golden fingers are firmly connected with PCB golden fingers, the connection strength of the FPC and the PCB is enhanced, and therefore, the welding quality of the FPC and the PCB is raised. The holes in the golden fingers are distributed in a staggered way, the holes in the golden fingers are stressed and staggered when the FPC is bent, and thus, the open holes can avoid cracks after concentrated stress. The strength of the golden fingers is enhanced, the reliability and the safety of the golden fingers are also enhanced, the reliability of the FPC is further and correspondingly enhanced, and the service life of the FPC is prolonged.
Description
Technical field
The present invention relates to a kind of flexible circuit board (FPC) golden finger that is used to improve bonding strength.
Background technology
Along with the quantity of FPC golden finger rolls up, the width of golden finger and gap can only reduce under limited space, like this when welding FPC and PCB, as shown in Figure 1, when the golden finger 1 ' of FPC and the golden finger of PCB4 ' 2 ' weld by scolding tin 3 ', the operator has some the electric iron of scolding tin to scrape rapidly from the golden finger 1 ' of FPC, scolding tin 3 ' can be from the front end stannize of the golden finger 1 ' on the FPC like this, but this mode is stannize effectively, cause failure welding to roll up, welding efficiency is low, has had 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 that is used to improve bonding strength is provided.
For achieving the above object, the present invention proposes a kind of FPC golden finger that is used to improve bonding strength, has the hole at FPC golden finger middle part.
The line of centres in described each hole forms a curve.
The center in described each hole lays respectively on the axis of golden finger.
Described hole is an arcuate socket.
Described arcuate socket is a circular hole.
The diameter of described circular hole is half of golden finger width.
Owing to adopted above scheme:
After FPC golden finger middle part is provided with the hole, when welding FPC and PCB, scolding tin in the end spot welding of FPC golden finger can penetrate in this hole 1, thereby realize effective stannize of FPC and PCB, make the golden finger of FPC firmly be connected with the golden finger of PCB, improve the bonding strength of FPC and PCB, thereby improve the welding quality of FPC and PCB.
Hole on each golden finger is in staggered distribution, and during the FPC bending, the stressed of hole on each golden finger is staggered, thereby avoid concentrating stressed after, the fracture of tapping improves the intensity of golden finger, strengthen the reliability and the fail safe of golden finger, the reliability and the useful life of further improving corresponding FPC.
It is arcuate socket that the hole is set, according to hydromechanical principle, be convenient to scolding tin flowing in the hole, make between FPC and the PCB fast stannize with firmly be connected, further improve bonding strength and the speed of welding of FPC and PCB, and then improve welding quality and the welding efficiency of FPC and PCB.
The tension force maximum of circular hole, the ability of absorption scolding tin is the strongest, and stannize is fastest between FPC and the PCB, and bonding strength is the highest, thereby can obtain welding quality and the welding efficiency of better FPC and PCB.
The diameter of circular hole is half of golden finger width, and both the intensity of guarantee fund's finger can not rupture because metal is very few, guaranteed the effect of stannize again, in the bonding strength that improves between FPC and the PCB, has also improved the reliability of FPC golden finger.
On the axis that is centered close to golden finger in each hole, the FPC golden finger is stressed evenly like this, and can realize even stannize, further improves the bonding strength between FPC and the PCB.
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 prior art FPC and PCB welded structure schematic diagram.
Fig. 2 is a structural representation of the present invention.
Embodiment
Embodiment, a kind of FPC golden finger that is used to improve bonding strength, as shown in Figure 2, have hole 1 at FPC golden finger middle part, like this when welding FPC and PCB, can penetrate in this hole 1 at the scolding tin of FPC golden finger end spot welding, thus effective stannize of realization FPC and PCB, make the golden finger of FPC firmly be connected, improve the bonding strength of FPC and PCB with the golden finger of PCB.
Because FPC usually can bend, the golden finger on it ruptures, and the hole 1 on each FPC golden finger is in staggered distribution, thereby makes the line of centres in each hole form a curve, further improves golden finger intensity, prevents that it from rupturing when stressed.
Described hole 1 is an arcuate socket, and according to hydromechanical principle, the flowing velocity of scolding tin in arc is faster, be more conducive between FPC and the PCB quick stannize with firmly be connected.In the present embodiment, hole 1 is a circular hole, since the flowing of circular the most suitable liquid, the tension force maximum, and the effect of absorption scolding tin is best.
For making the FPC golden finger stressed evenly, the center in each hole 1 lays respectively on the axis of golden finger.
Each hole 1 open excessive the time, metal is very few, then can reduce the intensity of golden finger, ruptures easily; And open too small the time, the institute adsorbable scolding tin very few, the effect of stannize is not good enough, through the experiment, in the present embodiment, the diameter of described circular hole is half of golden finger width.
