Abstract:
According to the present disclosure, a manufacturing method of a fine wiring pattern is disclosed. The manufacturing method includes preparing a support member, forming a first layer on the support member by thick-film printing, and forming a second layer including Ag on the first layer by the thick-film printing. The method also includes forming a predetermined fine wiring pattern by performing an etching process upon the first layer and the second layer.
Abstract:
An electronic device of the present invention includes an insulating base substrate in which a plurality of through electrodes are formed, an electronic element which is electrically connected to the through electrodes and is mounted on one surface of the base substrate, a lid which accommodates the electronic element and is bonded to the one surface of the base substrate, and an external electrode which covers a region from an end face of the through electrode, which is exposed by the other surface of the base substrate, to the other surface in the vicinity of the end face. The external electrode includes a conductive film which covers a region ranging from the end face to the other surface in the vicinity of the end face, and a paste film which covers a surface of the conductive film and is formed of a conductive paste. The paste film is formed by a printing method and is formed of tin or a tin alloy.
Abstract:
An electronic circuit contains a circuit board with conducting tracks to which one or more electronic components with conducting contacts are positioned overlying portions of the conducting tracks and each such electronic component is held in place by a clamp that is in contact with the top surface of the electronic components so as to hold their conducting contacts in electrical contact with the conducting tracks of the circuit board. The clamp can include a resilient layer held between the top surface of electronic components and a rigid clamping sheet.
Abstract:
A method of creating an active electrode that may include providing a flex circuit having an electrode made of a first material and providing a first mask over the flex circuit, the first mask having an offset region and an opening that exposes the electrode. The method may also include depositing a second material over the offset region and the opening, the second material being different from the first material and providing a second mask over the second material, the second mask having an opening over a portion of the second material that is over the offset region.
Abstract:
A method for producing an electrical component (1) is proposed, in which a ceramic base body (5) that contains a through-hole contact (10) and at least one metallization surface (20C) electroconductively connected to the through-hole contact is provided in a method step A). On the surface of the base body, an electrically insulating first material is arranged in layer form at least above the through-hole contact in method step B), and thereafter an electrically conductive second material is applied above through-hole contact (10) in method step C). Then a solder contact (30B) that electroconductively connects through-hole contact (10) through passivation layer (25B), which is formed from the first material by sintering, is formed by hardening in method step D).
