[Industrial application field]

This invention relates to a connector for signal observation, especially for LSI etc. mounted on a printed circuit board. This invention relates to a signal observation connector used when observing signals.

0002

[Conventional technology]

Conventionally, this type of signal observation connector has been used for LSI mounted on a printed circuit board. When performing actual device evaluation, a signal observation device mounted around the LSI on the printed circuit board. Wrapping posts or lead wires soldered to LSI terminals are used. was.

[Problem that the idea aims to solve]

The conventional signal observation connector mentioned above is an LSI connector mounted on a printed circuit board. When performing actual device evaluation, a signal observation rack mounted around the LSI on the printed circuit board is used. Ping posts or lead wires soldered to LSI terminals are used. , so space is required to mount the wrapping post on the printed circuit board. There is a problem that the lead wire must be soldered to the LSI terminal. Ru. In addition, examples from the measuring device one by one on the wrapping post or lead wire during measurement For example, there is a problem in that a clip or the like must be connected.

0004

[Means to solve the problem]

The signal observation connector of this invention is a film-like flexible base made of an insulating material. the flexible substrate with a conductive member for electrically connecting with the LSI terminal; There are multiple lands on the top, connectors for connecting to external measuring instruments, and equipped on the flexible substrate connecting between the plurality of lands and the connector. It has a conductive pattern.

【Example】 Next, the present invention will be explained with reference to the drawings.

[0006] FIG. 1 is a perspective view showing a flexible substrate for signal observation according to an embodiment of the present invention.

[0007] In Figure 1, a flexible signal observation connector is used as a signal observation connector in this embodiment. The board 1 includes a film-like flexible board 14 made of an insulating material, and an LSI terminal. The distance between LSI terminals is set on the flexible board 14 using a conductive member for electrical connection. Connect multiple lands 11 arranged according to the requirements and an external measuring device (not shown) a flexible connector 13 for connecting between the plurality of lands 11 and the connector 13; A conductive pattern is provided on a bull board 14.

[0008] FIG. 2 shows an application example of this embodiment, and (a) shows a book in which an LSI package is mounted. A diagram showing the case where the embodiment is mounted on a printed circuit board, (b) is the LSI in (a) FIG. 3 is a diagram showing a connection state between a terminal, a printed circuit board, and the present embodiment.

[0009] Next, with reference to FIG. 2(b), the shape of the land 11 and the land 11 and the LSI terminal 6 will be explained.

0010 The outer diameter of the land 11 is set to the minimum necessary diameter that can be fixed with the flexible substrate 14, The inner diameter is the same as or smaller than the LSI terminal 6. Also, the thickness of land 11 is, when the LSI terminal 6 penetrates the inner diameter of the land 11, the inner diameter of the land 11 has a capacity. The thickness should be such that it can be easily expanded. How to connect land 11 and LSI terminal 6 , an electrical connection is made by passing the LSI terminal 6 through the inner diameter of the land 11. .

[0011] Next, the signal observation flexible board 1 of this embodiment is attached to an LSI package 5. Attach it to the terminal 6, mount the LSI package 5 on the printed circuit board 7, and evaluate the actual device. A method for doing so will be explained with reference to FIGS. 1 and 2.

0012 When evaluating LSI package 5 on an actual device, print LSI package 5. Before mounting on the board 7, the signal observation flexible board 1 of this embodiment is connected to the LSI terminal 6. Install and then implement. The signal observation flexible board 1 is connected to the LSI package 5. It is fixed so as to be sandwiched between the lint substrates 7. Moreover, each signal of LSI terminal 6 is It is transmitted to the connector 13 by the land 11 and the pattern 12, and the external signal is transmitted to the connector 13. By connecting the cable 22 and connector 23 of the measuring instrument in the It becomes possible to observe the signal.

[Effect of the idea]

As explained above, the present invention is a film-like flexible base made of an insulating material. the flexible substrate with a conductive member for electrically connecting with the LSI terminal; There are multiple lands on the top, connectors for connecting to external measuring instruments, and equipped on the flexible substrate connecting between the plurality of lands and the connector. By having a conductive pattern, it is possible to print a terminal insertion type LSI. When performing actual device evaluation by mounting on a flexible board, the flexible board should be used as the LSI to be evaluated. After mounting, mount the LSI on the printed circuit board and connect it to the flexible circuit board. Since the signal at the LSI terminal can be observed from the terminal, it is possible to observe the signal around the LSI as in the past. Install a wrapping post for measurement, or use the solder side of the printed circuit board to connect the LSI terminals. This has the effect of eliminating the need to extract signals using lead wires. Also, measuring equipment and This has the effect of making the connection operation easier than before.
