Pressure application device for retaining at least two electronic components disposed opposite each other on each side of a connection board

An integrated circuit electronic card comprising

• pressure means for retaining at least two electronic components disposed opposite each other and on each side of a connection board,
• two rigid bearing plates disposed on each side of the connection board for exerting a retaining force by pressure on the electronic components in the direction of the connection board, and
• first clamping means for clamping the bearing plates to the connection board comprising at least one small clamping column, and
• resilient bracing means mounted at the end of said at least one clamping column for exerting a force on one of the bearing plates in the direction of the connection board, the connection board having openings in which said at least one clamping column is arranged to be mounted so as to be displaceable in translation in said openings in order to pass through the connection board at each end of the column, two fixing abutments for limiting the translation of said at least one clamping column through the connection board, said fixing abutments each being disposed on each side of the connection board, spaced from each other by a distance strictly greater than the thickness of the board so as to provide between the board and the abutments a clearance for balancing the retaining force between the two bearing plates.
