An electrical connecting member is provided with a holding member made of an electric insulating material and a plurality of conductive members held by the holding member in a state of being insulated with each other. One end of each of the conductive members is exposed on one surface of the holding member and the other end of each of the conductive members is exposed on the other surface of the holding member. The conductive members have portions exposed from the holding member, the length of which is longer than the thickness of the holding member. These exposed portions are easily deformed by the pressure force exerted at the time of connecting electric circuit components to reduce the coupling load even when there is irregularity in the heights thereof or unevenness in the junctions of the objects connection, hence enabling high density connections between the electric circuit components. The exposed portions can also be formed to have empty holes, i.e., to be porous, or in the alternative, annealed to soften the exposed portions. The holding member is formed by depositing several insulating layers such as resin on a conductive substrate, etching the substrate to form openings, filling the openings to form bumps, and then removing the substrate and an insulating layer thus leaving another of the layers of insulating materials as the holding member.

Method of making an electrical connecting member

A method for the electrical connection between electrical joints of electric circuit components includes disposing said electric circuit components so that said joints for the electrical connection are opposed to each other, and making the electrical connection between said electrical joints with a biasing force which is exerted by an elastic member from at least one side of said electric circuit component so that the biasing force is exerted consecutively from an intermediate position of connecting area where said joints are located to the periphery of said connecting area.

Electrical connections using deforming compression

An electrical connecting member is provided with a holding member made of an electric insulating material and a plurality of conductive members held by the holding member in a state of being insulated with each other. One end of each of the conductive members is exposed on one surface of the holding member and the other end of each of the conductive members is exposed on the other surface of the holding member. The conductive members have portions exposed from the holding member, the length of which is longer than the thickness of the holding member. These exposed portions are easily deformed by the pressure force exerted at the time of connecting electric circuit components to reduce the coupling load even when there is irregularity in the heights thereof or unevenness in the junctions of the objects connection, hence enabling high density connections between the electric circuit components. The exposed portions can also be formed to have empty holes 1B, to be porous or, in the alternative, annealed to soften the exposed portions.

Electrical connecting member

An electrical connecting member, one surface of which is connected to a connecting section of a first electrical circuit member and another surface of which is connected to a connecting section of a second electrical circuit member. The electrical connecting member includes a holding member formed of an electrically insulative member. The holding member has a plurality of recess holes. The connecting member also includes a plurality of electrically conductive members provided in the electrically insulative member, insulated from each other. One end of the electrically conductive members is exposed on one surface of the holding member to be connected to the connecting section of the first electrical circuit member. Another end of the electrically conductive members is exposed on another surface of the holding member to be connected to the connecting section of the second electrical circuit member.

A process for preparing an electrical connecting member having a holding member comprises an electrically insulating material, a plurality of electroconductive members equipped in the holding member under the state mutually insulated from each other, one end of the each electroconductive member being exposed at one surface of the holding member, and the other end of the each electroconductive member being exposed at the other surface of the holding member, the process comprising the steps of:

A process for preparing an electrical connecting member having a holding member with an electrically insulating material, and a plurality of electroconductive members. The electroconductive members are mutually insulated from each other and one end of each of the electroconductive members is exposed at one surface of the holding member and the other end is exposed at another surface of the holding member. A holding member is formed by forming a layer on a base member with the holding member having a photosensitive resin on the uppermost surface of the layer. The holding member is exposed and developed by forming a plurality of holes through the holding member, thereby exposing the uppermost surface of the layer. A part of the exposed layer is etched away and the holes on the holding member are filled with an electroconductive member. The remaining layer and base member are then removed.
