Abstract:
The connection structure between wired circuit boards connects a first wired circuit board and a second wired circuit board. The first wired circuit board includes a metal supporting layer, a first insulating layer formed on the metal supporting layer, and a first conductive pattern formed on the first insulating layer and having a first terminal portion. The metal supporting layer is arranged so as not to be opposed to the first terminal portion in a thickness direction. The first terminal portion and the first insulating layer opposed to the first terminal portion in a thickness direction are folded back into a curved shape. The second wired circuit board includes a second insulating layer, and a second conductive pattern formed on the second insulating layer and having a second terminal portion. The first terminal portion and the second terminal portion are electrically connected to each other.
Abstract:
An exemplary inner substrate for manufacturing multilayer printed circuit boards is provided. The inner substrate has a number of substrate units and a number of transverse folding portions alternately arranged along a longitudinal direction of the inner substrate. Each of the substrate units is configured for forming a unitary printed circuit board. Each of the folding portions is interconnected between neighboring substrate units. Each of the folding portions defines at least one line weakness perpendicular to the longitudinal direction of the inner substrate for facilitating folding and unfolding the neighboring substrate units to each other. An exemplary method for manufacturing multilayer printed circuit boards using the inner substrate is also provided. The method can improve efficiency of manufacturing multilayer printed circuit boards.

A storage apparatus includes an enclosure that has an opening in a bottom, and a carriage block. A flexible printed board has an upper part and a lower part, and a connector attached on an opposed surface of the lower part to a bottom plate of the enclosure inserted through the opening. A connector packing is fixed around the connector, with a catching part that stretches toward the flexible printed board. The flexible printed board has a first opening formed in the lower part, into which the catching part of the connector packing is infixed and a second opening formed in the upper part, into which the catching part of the connector packing fixed into the first opening is further fixed with the upper part folded on the lower part.
Abstract:
A multi-turn coil device comprising a flexible circuit board and a plurality of serially electrically coupled coils coupled to both sides of the flexible circuit board. The coils are formed such that when the circuit board is folded in an accordion manner, the coils are substantially aligned and have the same direction of current flow. The coils are serially coupled sequentially from front to back and back to front wherein the coupling of the coils is through a plated through hole in the flexible circuit board.

A plurality of first output terminals is provided along one side of a circuit element, and a plurality of input terminals and a plurality of second output terminals are provided adjacently along the other opposite side thereof. Leads include a first output lead extending from the first output terminal to an output connection electrode, and a second output lead extending from the second output terminal to the output connection electrode. The second output lead is extended from the other side of the circuit element to one side of the circuit element through a surface of a flexible wiring cable opposite the circuit element and further extended in parallel with the first output lead and connected to the output connection electrode.
Abstract:
The invention relates to a method for producing a three-dimensional circuit having at least two superimposed, flexibly formed substrate layers comprising conductor paths and/or circuit elements composed of electrical functional materials. The method has a combination of the following method steps: a. using a continuous sheet of material for the at least two substrate layers, b. printing the electrical functional materials onto the substrate layers, c. providing at least one folding or bending edge in the sheet of material in order to delimit the at least two substrate layers from each other, the folding operation being carried out inline with the printing operation, d. folding the sheet of material about the folding or bending edge after the conductor paths and/or circuit elements have been printed on, so that the at least two substrate layers are arranged one above the other.
Abstract:
The present invention can perform, at the time of mounting flexible printed circuit boards on a display substrate, the accurate alignment without wrong mounting. A first alignment mark and a second alignment mark for performing the alignment of a flexible printed circuit board with a display substrate are attached to left and right sides of a group of lines which are formed on the flexible printed circuit board. Further, when at least one of the first alignment mark and the second alignment mark is equally divided into four areas, a shape of the alignment mark in at least one area is a shape obtained by folding back the shape of the alignment mark in other areas.
