    • A system for performing an operation relating to a printed wiring board, including a first supporting table having a planar first supporting surface, a portion of the first supporting table that defines the first supporting surface being formed of a ferromagnetic material; a plurality of supporting members each of which has a seat portion having a bottom surface which is seated on the first supporting surface, and a support surface opposite to the bottom surface, a portion of the seat portion being formed of a permanent magnet, each supporting member being attached, owing to a magnetic force of the permanent magnet, to the first supporting surface to support a back surface of the wiring board; an operation performing device which performs an operation for a front surface of the wiring board whose back surface is supported by the respective support surfaces of the supporting members; a second supporting table which is provided in a vicinity of the first supporting table and has a second supporting surface which is substantially continuous with the first supporting surface on a common plane, a portion of the second supporting table that defines the second supporting surface being formed of a ferromagnetic material; and a supporting-member moving device which moves each supporting member from the second supporting surface to the first supporting surface, and vice versa, by sliding the supporting member on the first and second supporting surfaces.

    • An apparatus for holding a printed wiring board, including a holding table having a plurality of negative-pressure-supply holes in the upper surface, a holding member attachable to the upper surface of the holding table with a lower end surface, in contact with the holding table, surrounding the opening of one negative-pressure-supply hole. The holding member having a negative-pressure passage therethrough. The holding member supports, at an upper end surface, the printed wiring board, by applying a negative pressure via the negative-pressure-supply hole and the negative-pressure passage, to hold the board. An opening and closing valve associated with each negative-pressure-supply holes, to close the negative-pressure-supply hole where a holding member is not attached to the table and to open the corresponding hole, where a holding member is attached to the table to communicate with the negative-pressure passage.
    • 一种用于保持印刷电路板的装置,包括在上表面具有多个负压供应孔的保持台,具有下端面的与下端面相接触的保持件, 夹持台,围绕一个负压供应孔的开口。 保持构件具有穿过其的负压通道。 保持构件通过经由负压供给孔和负压通道施加负压来支撑印刷电路板的上端面,以保持电路板。 与每个负压供给孔相关联的打开和关闭阀,以将保持构件未附接到工作台的负压供给孔闭合并打开相应的孔,其中保持构件附接到工作台 与负压通道连通。
