Technical scheme in order to illustrate more clearly the embodiments of the present invention, below will be to that will use needed for embodiment description
Accompanying drawing be briefly described, it should be apparent that, drawings in the following description are only some embodiments of the present invention, for this
For the those of ordinary skill of field, without having to pay creative labor, other can also be obtained according to these accompanying drawings
Accompanying drawing.Wherein：
Fig. 1 is the schematic diagram of present invention metal lead wool in one embodiment；With
Fig. 2 is the schematic flow sheet of the manufacture method of present invention metal lead wool in a specific embodiment.
【Specific embodiment】
It is below in conjunction with the accompanying drawings and specific real to enable the above objects, features and advantages of the present invention more obvious understandable
The present invention is further detailed explanation to apply mode.
" one embodiment " or " embodiment " referred to herein refers in may be included at least one implementation of the invention
Special characteristic, structure or characteristic." in one embodiment " that different places occur in this manual not refers both to same
Individual embodiment, nor the single or selective embodiment mutually exclusive with other embodiment.
Refer to shown in Fig. 1, it is the schematic diagram of present invention metal lead wool in one embodiment.The metal lead wool
