Abstract:
The electronic module (BG) incorporates a specified separation edge (SAK, SAK1, SAK2, SAK3) for the mechanical, irreversible separation of a separable part (AT, AT1, AT2, AT3) of the module (BG) from the remainder of the module (BGR), both the separable part (AT, AT1, AT2, AT3) and the module remainder (BGR) incorporating essentially interacting circuit components (ST1, ST2) for an intended electrotechnical operation of the module (BG). By separating the separable part (AT, AT1, AT2, AT3) the electrotechnical operation of the module (BG) can be permanently deactivated.
Abstract:
A method of making a printed circuit board in which at least two circuitized substrates are aligned and bonded together (e.g., using lamination). A gasket is provided on one of these and a facing circuitized portion on the other. The gasket forms an effective seal about the circuitized portion to prevent heated dielectric material from contacting the circuitry. After bonding, parts of the bonded structure, including the gasket, are removed to leave a projecting edge portion having circuitry thereon. This edge portion is then adapted for being positioned within an edge connector.

Example embodiments of the inventive concept are directed to solid state device products, intermediate solid state devices, and methods of manufacturing and testing the same, with removable test terminals, which may permit in situ testing of one or more components of the solid state device products.
Abstract:
This device includes boards housing a large number of LEDs electrically connected with the tracks of a printed circuit, arranged in the board according to an equilateral triangular distribution and separated from one another at a fixed distance ‘a’, these light emitting diodes project beams of light interlacing from a certain distance ‘d’ of the board, giving even mass of light to the device at the above mentioned distance ‘d’, without points or appreciable zones of shadow. The boards are equipped with interlocking sections on both edges which are used as a guide for centering for the side connection of successive boards, as in a jigsaw puzzle, and the formation of a lighting panel having a larger surface.
Abstract:
The invention relates to a nonstick material for use during removal of a part (11) of a substantially planar material layer (2) which is connected in a connecting step to at least on further, substantially planar material layer (9). According to the invention, the nonstick material (8) has a different polarity than the adjoining, substantially planar material layers (2, 9). The invention also relates to a method for removing a part (11) of a substantially planar material layer (2) which is connected in a connecting step to at least one further, substantially planar material layer (9), to a multilayer structure which consists of at least two substantially planar material layers (2, 9) to be interconnected, and to a use of the same, especially in a multilayer printed circuit board.
Abstract:
A rigid-flex PCB includes at least one rigid PCB (RPCB) and at least one flexible PCB (FPCB). Each RPCB has a connection section; first and second sections separately extended from two lateral edges of the connection section and having at least one FPCB bonding side each; and a weakening structure formed along each joint of the connection section and the first and second sections. Each FPCB has a bending section corresponding to the connection section on the RPCB; first and second sections separately extended from two lateral edges of the bending section and having at least one RPCB bonding side each corresponding to the FPCB bonding sides of the first and second sections of the RPCB. When a proper pressure is applied against the weakening structures, the RPCB may be easily bent broken at the weakening structures to remove the connection section therefrom.
Abstract:
A wiring board including a main substrate having a base material and a conductive pattern formed on the base material, and a flex-rigid printed wiring board provided to the main substrate and having a rigid substrate and a flexible substrate connected to each other. The flex-rigid printed wiring board has a conductive pattern formed on the rigid substrate and/or the flexible substrate. The conductive pattern of the main substrate is electrically connected to the conductive pattern of the flex-rigid printed wiring board.
Abstract:
A cutting mold for removing two opposite superfluous rigid circuit boards from a rigid-flexible circuit board. A first cutter is connected to a first moldboard. A first barricade is connected to the first moldboard. The maximum vertical distance from the first barricade to the first moldboard exceeds that from the first cutter to the first moldboard. A second moldboard is opposite the first moldboard. The first and second moldboards move with respect to each other. A second cutter is connected to the second moldboard and corresponds to the first cutter. A second barricade is connected to the second moldboard and detachably abuts the first barricade. The maximum vertical distance from the second barricade to the second moldboard exceeds that from the second cutter to the second moldboard. The first and second cutters cut the superfluous rigid circuit boards when the first and second moldboards move toward each other.
Abstract:
A flexible wiring board includes a first flexible base material with a conductor pattern formed thereon, a second flexible base material disposed adjacent to the first flexible base material and an insulating layer covering the first flexible base material and the second flexible base material. The insulating layer exposes at least one portion of the first flexible base material. A conductor pattern is formed on the insulating layer, and a plating layer is provided connecting the conductor pattern of the first flexible base material and the conductor pattern on the insulating layer.
Abstract:
A method for manufacturing a multilayer FPCB includes the steps of: providing a first copper clad laminate, a second copper clad laminate and a binder layer; defining an opening on the binder layer; defining a first slit on the first copper clad laminate; laminating the first copper clad laminate, the binder layer and the second copper clad laminate; defining a via hole for establishing electric connection between the first copper clad laminate and the second copper clad laminate; cutting the first copper clad laminate, the binder layer and the second copper clad laminate thereby forming a multilayer flexible printed circuit board having different numbers of layers in different areas.
