た。2. Description of the Related Art In a conventional in-circuit emulator device, Teflon wires are connected one by one and used in a bundle.
A flexible printed wiring board using a polyimide copper-clad board has been used due to a decrease in connection reliability and an increase in man-hours. However, recently, the signal of a microprocessor has become faster and faster, and the signal delay time of a polyimide material cannot be ignored. Generally, the propagation speed of a signal is affected by the dielectric constant of a dielectric material constituting a transmission line. Dielectric constant of polyimide film used for conventional base material is 3.8 ~
In contrast to 4.2, the dielectric constant of the fluorinated organic composite is 1.8.
Since it is as small as about 2.3, both the signal propagation speed and the rise speed can be improved by about 30%. However, the base thickness of the fluorine-based organic composite material is 100 to 160 μm, which is 4 to 6 times as thick as that of a conventional polyimide material (base thickness 25 μm), so that the flexibility is deteriorated. Therefore, in order to improve the flexibility, conventionally, a continuous slit flexible wiring board 7 'provided with a continuous slit portion 8' as shown in FIG. 2 has been employed. However, although the flexibility is improved by this method, the stress is partially concentrated, the stress tends to be broken easily, and the handling is bulky because the slits are separated.

FIG. 1A is a plan view of the discontinuous slit flexible wiring board 1 of the present invention. FIG. 1B is a partially enlarged view of the discontinuous slit flexible wiring board 1 of the present invention. As can be seen from the drawing, the discontinuous slit flexible wiring board 1 of the present invention has a slit portion 2 and a non-slit portion 3 in the longitudinal direction along the pattern portion 4 in contrast to the conventional system having the continuous slit portion. And the non-slit portion 3 is provided on the diagonal line AB. Here, in order to improve the flexibility, the experiment was conducted under various conditions for the length M of the non-slit portion and the length L between the non-slit portions, and as a result, particularly preferable results were shown in the following cases. 1. The length M of the non-slit portion is almost the same as the slit width W. 2. The length L between the non-slit portions is about three times the slit width W. With the above structure, the discontinuous slit flexible wiring board 1 of the present invention may be used between the emulator 5 and the multilayer substrate 6 as shown in FIG. It becomes possible to bend smoothly without becoming.

ことはいうまでもない。Up to now, the discontinuous slit flexible wiring board 1 of the present invention has been described with reference to a case in which Teflon is used, but the invention is not limited thereto. Furthermore, although the description has been made of the example in which the non-slit portion 3 is provided on the diagonal line AB, it goes without saying that various modifications are included within the scope of the present invention in terms of design.

大きい。As described above, according to the flexible printed wiring board 1 with discontinuous slits of the present invention, the flexibility is improved, and the degree of freedom in the arrangement of devices can be obtained. Since lateral bending is possible, mounting in a limited space is possible. Since the middle of the flexible printed wiring board does not fall apart, handling becomes easy. Its industrial value is very great.
