Abstract:
The present invention relates to stretchable interconnects (10) which can be made in varions configurations. The stretchable interconnects can be made of an electrically conducting film (14) or an elastomeric material (16) to provide elastic properties in which the interconnects can be reversibly stretched in order to stretch and relax the elastomer material to its origional configuration.
Abstract:
A method for making a fine electrically conductive grid embedded in a polymer substrate (30). The method includes the steps of providing a polymer substrate (30), forming a pattern of grooves (31) in the substrate (30), filling the grooves (31) with electrically conductive powder, and then applying heat and/or pressure to the substrate (30). The application of heat and/or pressure to the substrate (30) causes the grooves (31) to collapse inward against the conductive powder. Collapsing the grooves (31) compacts the conductive powder within the groove (31), thereby establishing a continuously conductive grid line or circuit. The narrow grid lines that result allow more light to transmit through the substrate (30). The method allows grid lines to be made with higher aspect ratios (ratio of line depth to line width) than is possible by previous methods.
Abstract:
A method for manufacturing electrical connecting elements or semifinished products is disclosed. Starting from a plastically deformable dielectric substrate layer (1) being on its faces clad with a first and a second conducting layer (3, 5), microperforation combined with a welding or soldering process is carried out. To this end, the clad dielectric substrate layer (1) is placed between a perforation tool (11) having perforation tips (11a) and a support (13) and pressure is applied between the perforation tool (11) and the support (13), so that the perforation tips (11a) of the perforation tool (11) penetrate into the substrate material (1). The materials and the size and shape of the perforation tips (11a) are now chosen in a manner that the conducting material (5) is deformed and the dielectric substrate material (1) is thrust aside, conductor material of the first conducting layer (5) being displaced so that it gets into contact with conductor material of the second conducting layer (3) and is electrically and mechanically connected to conducting material of the second conducting layer.

A method of producing the bus bar wiring board comprising a bus bar pattern punching step for punching a bus bar pattern for electric wiring that is laid out in a predetermined shape out of an electrically conducting metal plate, a bus bar piece punching step for punching a bus bar piece laid out in a predetermined shape in a remaining space on the electrically conducting metal plate, and a connection step for electrically connecting and securing together the bus bar pattern punched in the bus bar pattern punching step and the bus bar pieve punched in the bus bar piece punching step, whereby reducing the waste in the electrically conducting metal plate out of which the bus bar patterns are punched and decreasing the cost of production or the cost of a product.
Abstract:
The positional tolerances required between contact pins on electrical components and the soldering eyes on flexible circuit boards make assembly work, in particular the production of soldered joints, difficult. The invention calls for a disc (25) to be placed over each contact pin (13) of an electrical component (12). The soldering eye (21) on the circuit board (15), which surrounds the contact pin (13) with a relatively large amount of play, is placed against the disc (25). The contact pin (13), the soldering eye (21) and the area of the disc (25) lying within the soldering eye (21) are then covered with solder (32). In equipment with soldered joints (31) produced in this way, the soldering eyes (21) on the circuit board (15) are contacted with the contact pins (13) of electrical components (12) by a solder bond (32) covering the soldering eye (21), the contact pin (13) and the area of the disc (25) inside the soldering eye.
