Abstract: A test device for testing integrated circuits includes a lid and a base joined at a hinge and secured together with a latch. Within the base is some form of socket body that electrically connects the integrated circuit under test to the item the socket is mounted to (i.e. load board). Attached to the lid are cam ratcheting levers. A pressure plate is attached to cam ratcheting levers. The cam ratcheting levers provide a rotating means for lowering a pressure plate by the use of the cam groove within the cam ratcheting levers. The means for lowering a pressure plate may allow incremental lowering of a pressure plate through the ratcheting action of the cam ratcheting levers. The base may include a sight groove for examination of the integrated circuit and internal socket parts.

Abstract: A test device for testing integrated circuits includes a lid and a base joined at a hinge and secured together with a latch. Within the base is a socket body that electrically connects the integrated circuit under test to the item the socket is mounted to (i.e. load board). Attached to the lid are bearing assemblies. An incline cam that may or may not include arresting points along the incline, rotates on the bearings which are attached to the lid. The cam, which is attached to the handle, translates rotational movement to vertical movement for lowering a pressure plate. This device may allow incremental lowering of a pressure plate by including stop points on the cam.
