Description

Detailed Description of the Invention 3. Detailed Description of the Invention [Field of Industrial Application] The present invention relates to an LSI cable connector that is characterized by LSI signal, power, and GND distribution.

[Prior Art] Conventionally, signals, power, and GND for an LSI chip have been provided only by wiring on a printed wiring board.

In other words, signal distribution, etc. is performed by the pattern of the printed circuit board, but in the case of the current high-density single-degree devices, the wiring length is long, so it is necessary to shorten the wiring length by increasing the layers of the printed circuit board. Measures were taken such as:

[Problems to be solved] In the conventional signal distribution mentioned above, it is done by the pattern of the printed circuit board, so in today's highly integrated world, it is difficult to do it over the shortest distance, and the wiring length It becomes long. As a countermeasure, is it possible to shorten the wiring length by increasing the number of layers on the printed circuit board?However, in that case, it is difficult to do so because the probability of accidents such as arrows and disconnections increases. There was a problem.

[Means for Solving the Problems] The present invention has been made by focusing on the above-mentioned problems of the conventional art.
Signal distribution is possible, the shortest distance connection is possible, and signal timing can be easily changed.
Furthermore, it is an object of the present invention to provide an LSI cable connector that can reduce the probability of accidents such as wire breakage, etc., and can be easily repaired and replaced in the event of an accident.

To this end, the present invention provides a cable connection part that connects a cable to a pin contact part that contacts a single pin or a plurality of pins arranged in a row adjacently to a pin of a pin grid array package, and a cable connection part that connects the pin contact part and a cable. a thin plate having wiring that electrically connects the thin plate; and a conductive metal that is attached to the pin contact portion of the thin plate and electrically connects the pin and the pin contact portion, or an insulation that insulates the 11τf pin and the pin contact portion. LSI consisting of a connecting part made of a body, and a spring that fixes a plurality of thin plates connected to the thin plate 1v1 and having a connecting part of a conductive metal or an insulator attached to the pin contact part to a pin grid array package. The present invention provides cable connectors for
