Abstract:
A resonance security tag (1) comprises a dielectric foil material (2) provided with conductive material layer patterns (3-7) on both sides. The conductive material layer patterns are formed to provide an inductor (3) and a capacitor (4, 6) positioned inside the inductor (3), and mutually connected to form a resonance circuit. By cutting (9) the capacitor (4, 6) free of the dielectric foil material (2) and folding the capacitor (4, 6) away from the position inside the inductor (3), this part is left free for the penetration of magnetic flux through the inductor (3), whereby the detection level is improved and a possibility of reducing the size of the resonance security tag is provided.

Abstract:
A method and apparatus for through-contacting flexible substrates 1, in particular circuit boards, having electrically conductive contact zones 4, 41 present on two opposing surfaces 1a, 1b of the substrate provides that a cut 11 is produced obliquely to the surfaces of the substrate in the area of the contact zones, and the two substrate areas 20, 30 adjoining the oblique cut are moved past each other until they lock behind each other. Moving them past each other is effected by a ram 12, by the action of compressed air 13, by applying a vacuum 14 or by a driving hook 15 fixed to the cutting tool. The two steps of producing the cut and moving the two substrate areas adjoining the cut past each other are effected in a common processing station, preferably in a single operation.
Abstract:
An assembly includes a structure, a plurality of terminals and a plurality of compliant pads disposed between said terminals and said structure. The terminals are aligned with at least some of said pads, with the pads providing a standoff between the structure and the terminals. The compliant pads are preferably made of a non-conductive material such as a silicone elastomer.
Abstract:
Modules for fixing flexible printed circuit boards. A module comprises a casing and a flexible printed circuit board. The casing has a recess on a lateral side. The flexible printed circuit board has a flexible portion disposed in the recess, wherein the thickness of the flexible portion is substantially equal to the thickness of the recess.
Abstract:
An interconnect for testing semiconductor components includes a substrate, and contacts on the substrate for making temporary electrical connections with bumped contacts on the components. Each contact includes a recess and a pattern of leads cantilevered over the recess configured to electrically engage a bumped contact. The leads are adapted to move in a z-direction within the recess to accommodate variations in the height and planarity of the bumped contacts. In addition, the leads can include projections for penetrating the bumped contacts, a non-bonding outer layer for preventing bonding to the bumped contacts, and a curved shape which matches a topography of the bumped contacts. The leads can be formed by forming a patterned metal layer on the substrate, by attaching a polymer substrate with the leads thereon to the substrate, or be etching the substrate to form conductive beams.
Abstract:
A flexible circuit board. The flexible circuit board is connected to an LCD module, comprising a first conductive portion, a second conductive portion, a third conductive portion, a conductive trace and a slot. The second conductive portion is disposed at the border of flexible circuit board and comprises a first contact pad. The third conductive portion is located between the first and second conductive portions. The conductive trace comprises a first trace segment a second trace segment. The first conductive segment connects the first conductive portion with the first contact pad, and the second trace segment connects the second conductive portion with the third conductive portion, wherein the slot is formed between the first and second trace segments.
Abstract:
At least two components are brought to rest on each other at least in an assembly portion, with a carrier element contacting a first one of the two components at least in the assembly portion, and at least one projection passing through the components in the assembly portion in the direction towards the carrier element. The carrier element is planarly supported at least in the assembly portion against the passing-through movement of the projection, and the passing of the projection through the components. The opposed planar support of the carrier element effects a plastic deformation of the passed-through material of the components in the direction transversely to the passing-through movement of the projection by deforming the carrier element.
Abstract:
Probes for electronic devices are described. The probe is formed by ball bonding a plurality of wires to contact locations on a fan out substrate surface. The wires are cut off leaving stubs. A patterned polymer sheet having electrical conductor patterns therein is disposed over the stubs which extend through holes in the sheet. The ends of the wires are flattened to remit the polymer sheet in place. The wire is connected to an electrical conductor on the polymer sheet which is converted to a contact pad on the polymer sheet. A second wire is ball bonded to the pad on the polymer sheet and cut to leave a second stub. The polymer sheet is laser cut so that each second stub is free to move independently of the other second studs. The ends of the second stubs are disposed against contact locations of an electronic device, such as an FC chip, to test the electronic device.
Abstract:
Contact-making device and method for connecting an electric conductor, in particular a wire-like and/or thread-like electric conductor which is arranged in a textile material, electrically to an electronic component. The device includes a substrate material, and at least one contact, which is formed on the substrate material, to connect the electric conductor electrically to the electronic component, the contact comprising a movable section and an immovable section. The movable section is formed such that, during the electrical connection operation, it is arranged substantially on a surface side opposite the immovable section.
