Abstract:
A wiring body (3) includes a resin layer (31), an electrode layer (320) provided on a surface of the resin layer (31) at one side, and a lead wiring layer (324) provided on the surface of the resin layer (31) at the one side and formed integrally with the electrode layer (320). The lead wiring layer (324) has a single-layer structure made of a material having the same composition as that of a material constituting the electrode layer (320). A following Expression (1) is satisfied: T 1 2 ...(1). In the above Expression (1), T 1 is a thickness of the electrode layer (320), and T 2 is a thickness of the lead wiring layer (324).
Abstract:
A printed circuit board according the presrnt embodiment includes an insulating layer; at least one circuit pattern or pad formed on the insulating layer; a solder resist having an opening section exposing the upper surface of the pad and formed on the insulating layer and a bump formed on the pad exposed through the opening section of the solder resist and having a lower area narrower than the upper area.
Abstract:
A wiring substrate includes a surface layer having electrical insulation properties and a connection terminal having electrical conduction properties and protruding from the surface layer. The connection terminal includes a base portion, a covering portion and a filling portion. The base portion of the connection terminal is made of an electrically conductive first metal and located adjacent to the surface layer so as to extend through the surface layer and protrude from the surface layer. The covering portion of the connection terminal is made of an electrically conductive second metal having a melting point lower than that of the first metal and located so as to cover the base portion. The filling portion of the connection terminal is made of at least one of the second metal and an alloy containing the first and second metals and located so as to fill a hollow in the base portion.
Abstract:
The invention relates to a method for connecting a component (1) to a carrier (6) via soldering between a first contact surface (11), on the component, and a second contact surface (61), on the carrier (6). The method is characterized in that at least one spacer (2) is designed and arranged between the first contact surface (11) and the second contact surface (61) in such a manner that the first contact surface and the second contact surface are spaced apart from one another, and that the soldering is performed in such a manner that the component (1) and the carrier (6) are connected to one another via the first contact surface (11) and the second contact surface (61). A component (1) for connection to a carrier (6) via soldering is also claimed.
