  • Publication number: 20170243808
    Abstract: A joined body of the embodiments is a joined body which includes copper and resin, wherein in a joint surface of the copper to the resin, a triazine thiol derivative, or the triazine thiol derivative and a silane coupling agent are bonded to a base surface and the silane coupling agent is bonded to an oxide film formed on part of the joint surface, respectively, and the copper and the resin are molecularly joined to each other. This configuration makes it possible to obtain a joined body having high reliability by molecularly joining both the base surface and the oxide film of the copper, and the resin securely and achieving a strong joint of the copper and the resin at a time of joining the copper and the resin even though the oxide film is formed on part of the joint surface of the copper.

  • Publication number: 20150189751
    Abstract: A wiring board includes a conductor formed on an inner wall of a through hole made in a core board, resin formed inside the conductor in the through hole, and, for example, a land formed over the conductor and the resin. Vias are formed over the land. The vias are connected to a plurality of connection regions of the land extending over the conductor and the resin in the through hole. The land is held by the vias connected to the plurality of connection regions. This controls the thermal expansion of the resin to a land side and therefore prevents a fracture of the land.

  • Patent number: 7388157
    Abstract: A printed wiring board is made of first and second substrates superimposed on each other. The first and second substrates respectively include a core layer made of resin containing carbon fibers. The second substrate has the outline different from that of the first substrate. A stepped surface is defined on the front surface at least of the first substrate. Electrodes can be formed on the stepped surface as well as on the back surface of the first substrate and the front surface of the second substrate. This structure enables detection of an electric signal from the stepped surface. A further flexibility can thus be achieved in locating electrodes as compared with a conventional printed wiring board having uniform substrates simply superimposed on each other. This results in an expanded use or purpose for a printed wiring board.
