    Abstract: The invention provides a stacked structure comprising a master circuit board and at least two slave circuit boards. The master circuit board comprises a plurality of connecting seats. Each slave circuit board is equipped with a connector, and defined with a plurality of post-production process areas. Wherein the connector of each slave circuit board is disposed on one of post-production process areas, and inserted into the corresponding connecting seat. When the connector of the slave circuit board must be through other slave circuit boards in order to insert the corresponding connecting seat, the post-production process areas that are disposed on other slave circuit boards and impede the connection between the connector and the corresponding connecting seat will be cut into hollow areas. Accordingly, the connector of the slave circuit board is capable of inserting the corresponding connecting seat through the hollow areas of other slave circuit boards.

    Abstract: A printed wiring board including: a first substrate on which a plurality of pads to be connected to a connector is arranged to form a front array and a rear array in two rows; a second substrate that is laminated on the first substrate and formed with first wirings connected to first pads of the front array and second wirings connected through vias to second pads of the rear array; engageable parts that are to be engaged with engagement parts of the connector; and one or more reinforcement layers that are provided at the frontward side in the connecting direction than the engageable parts of the first substrate and/or the second substrate. The wirings each have a part formed to have a constant width along the inserting direction to the connector and an expanded-width part expanded to have a wider width than the constant width in the inserting direction of the connector.
