Abstract : A clamping device for securing a workpiece such as an electronic package to a support such as a heat sink. A curved slot is machined around a central opening in the body of a configurated flat metal clamp having an extending lip which contacts the edge of the workpiece. The central opening in the clamp body receives a hold down screw member which threadably engages the support. When the hold down screw is fully tightened against the support with the extending lip over the workpiece, the known clamping force predetermined by the thickness and configuration of the clamp body is applied. The need for a torque wrench and specific fastener torque values to prevent possible distortion of the surface of the heat sink is eliminated. (Author)
