Small tin sweat(ing) residual, improves welding quality.
3. in said program, the flake main body is segmented, including the identical fragment body of two shapes；Two fragments
Body along the carrier middle through-hole central point center symmetric setting, and on each fragment body include the first end and institute
State second end.
4. in said program, the first end of the flake main body be equipped in the second end of the flake main body it is multiple fixed
Position hole.Convenient for the positioning on jig or carrier, voice coil motor pedestal.
5. in said program, the second end of the flake main body is equipped with tube chamber welds with base pad, for welding positioning voice coil horse
The pedestal reached.
6. in said program, shrapnel of the invention is specifically related to the lower shrapnel of voice coil motor.
The operation principle and advantage of the present invention is as follows：
A kind of novel shrapnel of voice coil motor of the present invention, flake main body be equipped with the first end being connected with lens carrier and with
The second end that voice coil motor pedestal is connected；It is connected by bending the shrapnel string silk of setting between first end and second end；First
End is equipped with a solder pad, is welded and is positioned by the solder pad and the coil being wound on carrier；Solder pad includes welding
Golden finger and molten tin notch, molten tin notch include the first notch and the second notch of connection, and welding golden finger position is in the first notch
In.
Compared to existing technologies, present invention optimizes solder pads, increase welding golden finger and molten tin notch；Pass through
Welding golden finger increases bonding area, helps to weld golden finger and the more preferable welding of coil, improves the stability of welding, energy
Desoldering is enough avoided the occurrence of, on the other hand can avoid small tin sweat(ing) residual by melting the design of tin notch；Therefore life can effectively be promoted
Efficiency and production stability are produced, yields is improved, and do not have to hand inspection and heavy industry, effectively saves manpower and cost.
