Abstract:
Parameters relating to wireless communication in a wireless network system are set in a printer, which is to be wirelessly connected to the network system anew, from a personal computer that is already wirelessly connected, and the personal computer acquires identification information of the printer and transmits this identification information to an access point. The access point sets up the connection to the printer based upon the identification information that has been transmitted from the personal computer. This makes it possible to connect a new wireless communication apparatus to a wireless network system through a simple set-up operation.

Abstract:
To provide a printed wiring board and a method for manufacturing the printed wiring board in which circuit widths of a signal transmission circuit and a power supply circuit or the like, which conventionally require to have greatly different circuit widths, are close to each other as much as possible and substantial miniaturization can be achieved. In order to achieve this object, a printed wiring board obtained by etching a metal-clad laminate including a conductive layer and an insulating layer is employed, in which a first circuit and a second circuit having different thicknesses formed in a same reference plane coexist. In addition, it is characterized in that a thicker circuit of the first circuit or the second circuit has a clad-like configuration in which three layers of a first copper layer/a different kind of metal layer/a second copper layer are sequentially stacked. Further, a manufacture of the printed wiring board is characterized in that a clad composite material in which three layers of a first copper layer/a different kind of metal layer/a second copper layer are sequentially stacked is a start material, and selective etching characteristic between the different kind of metal layer and the copper layer is effectively utilized.
