Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to a method for manufacturing a dielectric wire used in wiring boards.

2. Description of the Related Art Conventionally, jumping wires for reprinted wiring boards have been manufactured by forming a metal wire into a desired shape and then cutting it, or by cutting it and then forming it into a desired shape.

However, in this conventional method for manufacturing jumping wires, a special automatic machine for the sole purpose of manufacturing jumping wires is used.1. However, since the required quantity of 7iW for the jumping line itself is limited, there was a problem that the unit price was higher than expected due to the cost of the dedicated automatic machine + 1Ilitit shipping cost.

OBJECTS OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and its purpose is to provide a low-cost method for manufacturing disembedding wires for wiring boards.

SUMMARY OF THE INVENTION To summarize this invention, the central part has a CU shape): 1. Both ends of one bent metal wire are connected to the main body of the electronic component,
In the process of forming lead terminals for electronic components, in which the L-shaped portion is cut and removed and the remaining portion is used as a lead terminal, the U-shaped portion of the gold RIa is formed into a desired shape before cutting, and then cut. Alternatively, this is a method for manufacturing a jumping wire for a printed wiring board, in which a jumping wire is manufactured by cutting and then forming into a desired shape.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention using a capacitor element as an electronic component body will be described with reference to the drawings.

First, as shown in Fig. 1, a capacitor element 3 with electrodes 2 formed on both sides is connected and fixed by soldering or the like to both ends of a single metal wire 1 having a curved (1-shaped part 1a) in the center. Then, as shown in FIG. 2, a resin 4 is coated on the surface of the capacitor element 3 by a dipping method or the like.

Next, as shown in FIG. 3, the U-shaped portion 1a of the metal wire 1 is formed into a shape having a width W and a height t desired as a jumping wire, and then cut at a portion of the line A-A, and printed. Jumping wire for wiring board roars. In addition, U
After the character-shaped portion 1a is cut, the metal wire 1, that is, the lead terminal of the capacitor, may be further cut into a desired length as the lead terminal of the capacitor.

The above is one embodiment of the present invention, and it goes without saying that the design may be modified without departing from the spirit of the invention. For example, in this embodiment, the electronic component 3 is used as the main body of the electronic component, but the present invention is not limited to this. Further, although the U-shaped portion 1a is formed into a desired shape as a jumping wire and then cut from the metal wire 1, the present invention also applies when the U-shaped portion 1a is cut from the metal wire 1 and then formed into a desired shape as a jumping wire. belongs to Furthermore, when forming the U-shaped portion 1a by curving the metal wire 1, the present invention also includes a case where the U-shaped portion 1a is previously formed into a desired shape as a jumping wire.

Effects of the Invention As is clear from the above explanation, the method for manufacturing jumping wires for printed wiring boards of the present invention manufactures jumping wires from unnecessary parts of lead terminals of electronic components that are normally discarded. Further, the manufacturing process can be included in the lead terminal forming process of electronic components, and both processes can be incorporated into the same automatic machine, so the unit price of the jumping wire can be significantly reduced.
