In particular, in a mounting device for a computer, there is a logic card in which a logic element is implanted on a circuit board as an electronic circuit module.

[0003] Computers are required to have a high processing speed. In order to realize a computer with a high processing speed, it is useful to achieve high integration not only of the circuit elements but also of an electronic circuit module or the like at an upper mounting level and to shorten the mounting wiring length. Regarding the mounting device for a computer, the processing time of the computer greatly depends on the electrical distance between a plurality of logic cards or a plurality of logic elements. Therefore, when a large number of logical cards are mounted, or when a logical card is large by including large components such as a heat sink for cooling a logical element on the logical card, the logical The physical distance increases, and as a result, the electrical distance increases, and the processing time of the computer decreases.

[0004] Computers are also required to have a small configuration. For example, a computer in recent years may be required to be a deskside type or to be able to be stored in a standard-standard storage device such as an EIA rack. As a countermeasure, an example has been proposed and implemented in which a configuration is adopted in which a logic card is connected to each side of the backplane of the mounting apparatus (sometimes called a double-sided logic cage) to realize a small mounting apparatus. ing. According to this mounting apparatus, a short mounting wiring length can be realized.
