Sheet material having metal points and method for the production thereof

摘要

The invention relates to a sheet material having metal points ( 8 ) and surfaces ( 2 and 3 ) located opposite one another, wherein the sheet material ( 1 ) has through-holes ( 4 ) from one surface ( 2 ) to the surface ( 3 ) located opposite. Those through-holes ( 4 ) are filled with needle-point-shaped conical pins ( 5 ) or through-contacts ( 6 ) of electrically conducting material, whereas the surrounding sheet material in a preferred embodiment of the invention consists of an insulating plastics material ( 7 ). In a further embodiment of the invention, instead of the insulating plastics material ( 7 ) there are provided needle-shaped pins that are surrounded by air or some other gaseous medium. The invention further relates to a method for the production of such a sheet material ( 1 ) and to forms of use of the sheet material ( 1 ).
