Circuit board device, wiring board connecting method, and circuit board module device

Abstract

Provided are a circuit board device, a wiring board connecting method and a circuit board module device, which control the compressibility of anisotropically conductive members within the most proper range, which suppress the dispersion of the impact resiliences of the anisotropically conductive members even if a lamination number increases, which can suppress the deformation of the wiring board and the fluctuations of the impact resilience of the anisotropically conductive members even if a static external force or the like is applied, which suppress the linear expansion of the anisotropically conductive members, even if the ambient temperature changes, to raise the stability of electric connections, and which can reduce the impact resilience of the anisotropically conductive members thereby to reduce the thickness. The circuit board device comprises wiring boards (101 - 104), anisotropically conductive members (105) arranged between the individual wiring boards, functional blocks (106) made separate of the anisotropically conductive members (105) and so arranged on the plane common to the anisotropically conductive members (105) as to enclose the anisotropically conductive members (105), and a pair of holding blocks (107, 108) arranged to sandwich the wiring boards (101 - 104). These wiring boards (101 -104) are compressed and held while being clamped between the paired holding blocks (107, 108), so that they are electrically connected with each other by the anisotropically conductive members (105).

Description

technical field [0001] The present invention mainly relates to a circuit board device having a plurality of wiring boards on which printed metal lines are laid, such as flexible printed wiring boards, rigid printed wiring boards or the like configured in electronic equipment in the field of electronics and communications, Among them: the wiring boards are stacked and kept connected to each other. Furthermore, the present invention relates to a wiring board connection method for connecting these wiring boards to each other, and a circuit board module device. Background technique [0002] Recently, for example, mobile phones, PDA (Personal Digital Assistant) terminals, and many other electronic devices include a plurality of printed wiring boards on which printed metal lines are laid and a plurality of electronic parts mounted, and are included in electronic devices of limited volume. Then, as the thickness and volume continue to decrease, various techniques have been disclos...
