A method for manufacturing a printed circuit board assembled panel by a simple process with an excellent material yield and a high conforming product rate. Unit printed circuit boards previously manufactured are arranged in a frame in a prescribed relationship. Then, the printed circuit boards are fixed to one another, and the printed circuit board and the frame body are fixed to one another.

Printed circuit board assembled panel, unit sheet for packaging a printed circuit board, rigid-flexible board and method for manufacturing the same

A rigid-flexible board and a method for manufacturing the same can be provided, whereby the material yield ratio can be enhanced and the productive yield can be also enhanced. A rigid board with a step for connection and a flexible board with a connector at the edge thereof are formed independently. Then, the connecting area is spot facing processed so that the depth of the thus obtained depressed portion is equal to or lower than the thickness of the flexible board. The connector of the flexible board is electrically connected to the vertical wiring area of the depressed portion.

A wireless suspension blank is made using a two-layer laminate composed of a metallic layer with the spring property and an electrically insulating layer. The first method includes a first step for working the metallic layer by the photo etching method, a second step for forming a wiring part on the insulating layer by the semi-additive method and a third step for working the insulating layer by the wet-etching method. The second method includes a first step for working the metallic layer by the photo etching method, a second step for forming a wiring part on the insulating layer by the semi-additive method and a third step for working the insulating layer by the plasma etching method. The third method includes a first step for forming a wiring part on the metallic layer by the semi-additive method, a second step for working the metallic layer by the wet-etching method and a third step for working the insulating layer by the dry-etching method or the wet-etching method. The use of a two-layer laminate makes possible a low cost production. Further, the forming of a wiring part by the semi-additive method makes possible to working very accurately a fine wiring part.

Method of manufacturing wireless suspension blank

A method of manufacturing a wireless suspension blank wherein three-layered laminate formed of a metallic layer having a spring property and a conductive layer laminated on the metallic layer through an electrically insulating layer are used. The laminate used is a laminate in which an insulating layer is formed of a core-insulating layer and adhesive layers laminated on both sides of the core-insulating layer, and the ratio of higher etching rate to lower etching rate of the respective layers of the insulating layer is between 6:1 and 1:1. The metallic layer and the conductive layer are processed by the photo etching method. The insulating layer is processed by the wet etching method.

An electrode for a rechargeable battery with a nonaqueous electrolyte is provided wherein the active material layer has a sufficient flexibility, the adhesion between the active material coating and the metal foil collector is good, none of peeling, falling, cracking and other unfavorable phenomena occur in the active material coating in the step of assembling a battery and excellent discharge characteristics can be developed. The electrode for a rechargeable battery with a nonaqueous electrolyte comprises a metal foil collector and, formed on at least a part of the metal foil collector, an active material layer comprising an active material and a cured reaction-curing binder as essential components.

Electrode for rechargeable battery with nonaqueous electrolyte and

A packaged electrode plate for a secondary battery with a nonaqueous electrolyte comprises: an airtight container having a winding core and a tape pulling-out opening; and a wound tape comprising an electrode plate for a secondary battery with a nonaqueous electrolyte. The wound tape is stored in the airtight container and supported on the winding core thereof. A forward end of the wound tape is pulled out from the tape pulling-out opening of the airtight container, and the tape pulling-out opening is hermetically closed by means of an airtight sealing means which holds the forward end of the wound tape pulled out from the tape pulling-out opening.
