Micro Contact Probe for IC Testing

SEI has developed a mass-production process for ultra high precision mechanical components using X-Ray lithography (Synchrotron Radiation), SEI's proprietary electroforming and molding technique. The X-ray lighographic process provides a very precise pattering by X-ray that offer very accurate perpendicularity and sharpness. The metal is electroformed to the desired pattern in a very small grain size and well-controlled crystal orientation due to SEI's proprietary process which produces a very high hardness in the metal. This technology can be applied to any micro mechanical component; micro contact probe for IC testing, various types of injection metal mold tools, etc.
