Fig. 3 is a schematic view showing the structure of a printed wiring board according to the present invention.

The following provides a printed circuit board for the present invention with reference to the accompanying drawings. The specific implementation of the jumper and the printed circuit board using the jumper will be described in detail.

First, a specific embodiment of a jumper for a printed wiring board according to the present invention will be given with reference to the accompanying drawings.

Referring to the second embodiment shown in FIG. 2A-2C, the structure of the jumper for the printed circuit board is provided at different viewing angles. The jumper 20 is a sheet-like structure, and includes a body 22, the body 22 is covered with an insulating layer 23; the two ends of the body 22 are bent in the same direction and extend to form two bent portions 21, all of the bent portions 21 are Parallel to the body 22 for soldering to a surface of a PCB (not shown). The width and length of the jumper 20 can be adjusted according to the needs of the wiring. For example, jumpers 20 of different lengths can be used according to different cross-regional requirements; corresponding widths can also be used to meet the demand for excessive current.

Since all of the bent portions 21 are in the form of a sheet, which has a single panel property and easy patchability, SMT (Surface Mounted Technology) can be used to realize complete automatic patch mounting, thereby effectively improving production efficiency.

The material of the bent portion 21 and the body 22 is copper. The four surfaces 221, 222, 223, and 224 of the body 22 are each covered by an insulating layer 23 composed of an insulating property material. Since the body 22 has good insulating properties, the two bent portions 21 have single panel properties and easy patchability, so the jumper 20 can be applied to any position of the copper foil surface of the PCB; and when the PCB is a double panel, The jumper 20 can also be applied to the part face of the PCB. That is, the jumper 20 can meet various wiring requirements and save PCB wiring space during design and use.

The jumper 20 can be a sheet metal coated with an insulating layer itself. The material is removed from the insulating layer at both ends to form two bent portions; or after etching with a metal material (for example, a copper plate), an insulating layer is coated on the body portion.

Next, a specific embodiment of the printed wiring board described in the present application will be given with reference to the accompanying drawings.

Referring to FIG. 3, a schematic structural view of a printed wiring board provided by this embodiment is shown. At least one jumper 20 is soldered to the printed wiring board 30.

Both ends of the body 22 are bent toward the surface of the printed wiring board 30 and extend to form two bent portions 21, all of which are parallel to the body 22, and the bent portion 21 is welded to the surface of the printed wiring board 30. .

The jumper 20 can be soldered to the copper foil face or the component face of the printed wiring board 30 by an automatic patch mounting method. When the printed wiring board 30 is a single panel, the jumper 20 can be soldered to the copper foil surface 31; when the printed wiring board 20 is a double panel, the jumper 20 can be soldered to the part surface (not shown). In the present embodiment, the jumper 20 is soldered to the back surface of the printed wiring board 30, that is, the copper foil surface 31 by an automatic patch mounting method.

The body 22 of the jumper 20 may be provided with a copper foil in the projection area of the copper foil face 31. When the length of the jumper 20 is satisfactory, a plurality of copper foils may be disposed in the projection area, as shown in the figure, through the copper foils 311, 312 and 313 at the bottom of the body 22 having insulating properties, each copper foil (311, 312 and 313) can have Different electrical characteristics. Therefore, the jumper 20 can be applied to any position of the copper foil surface 31 of the PCB, which satisfies the requirements of various wirings, effectively saves the wiring space of the PCB, and the automatic patch mounting method effectively improves the production efficiency.
