Abstract:
A process for producing a printed wiring board-forming sheet comprising a resin sheet having a through hole in the thickness direction and a metal chip inserted in the through hole. The sheet is produced by placing a resin sheet and conductive metal sheet in this order on a die base having a die hole, performing punching from the conductive metal sheet side to form a punched hole in the conductive metal sheet and to form a punched hole in the resin sheet and inserting the punched conductive metal chip in the through hole of the resin sheet whereby the front and back surfaces of the sheet can be electrically connected to each other. If the conductive metal chip is so inserted that its tip protrudes from the surface of the sheet, and if a large number of such substrates are laminated, electrical connection in the thickness direction can readily be made by virtue of the protruded conductive metal chips and a multi-layer board can be readily produced.
Abstract:
A sheet for forming a printed wiring board which comprises a resin sheet (18) having a through-hole in the thickness direction and a metallic chip (46) inserted into the through-hole, and a method of manufacturing this sheet. The resin sheet (18) and a conductive metallic sheet (44) are placed in this order on a die base (16) having a die hole (14), then a hole is formed in the conductive metal sheet (44) with a punch (10) from the conductive metal sheet (44) side. At the same time, a hole (20) is also formed in the resin sheet, the conductive metal chip (46) formed by the punching from the conductive metal sheet (44) is inserted into the through-hole formed in the resin sheet (18). Thus, the sheet is manufactured. The front and rear surfaces of the sheet can be electrically interconnected by inserting this conductive metal chip (46) into the through-hole, and many substrates are stacked and by protruding and inserting the conductive metal chip (46). Thereby, the sheets can be electrically connected in the thickness direction by this protruded conductive metal chip (46) and a multilayer laminated board can be easily manufactured.
Abstract:
The present invention provides a printed wiring board-forming sheet comprising a resin sheet having a through hole in the thickness direction and a metal chip inserted in the through hole, and a process for producing the sheet. The sheet is produced by placing a resin sheet and a conductive metal sheet in this order on a die base having a die hole, performing punching from the conductive metal sheet side to form a punched hole in the conductive metal sheet and to form a punched hole also in the resin sheet, and inserting the punched conductive metal chip in the through hole of the resin sheet. By the insertion of the conductive metal chip in the through hole, the front and back surfaces of the sheet can be electrically connected to each other. If the conductive metal chip is so inserted that its tip protrudes from the surface of the sheet and if a large number of such substrates are laminated, electrical connection in the thickness direction can be readily made by virtue of the protruded conductive metal chips, and a multi-layer board can be readily produced.
Abstract:
A flexible device includes a first conductive pattern, a second conductive pattern, and a dielectric layer. The first conductive pattern includes a first sliding contact portion and a first extension portion. The second conductive pattern includes a second sliding contact portion overlapping with the first sliding contact portion and the second conductive pattern includes a second extension portion. The second sliding contact portion is in contact with the first sliding contact portion and is movable on the first sliding contact portion for a sliding motion. The first and second conductive patterns are embedded in the dielectric layer.
