Abstract: A test socket includes a housing and a mounting portion extending from the housing and including an accommodation space configured to mount a semiconductor device thereon. A lower surface of the mounting portion includes a plurality of holes corresponding to a plurality of pins included in the semiconductor device, the plurality of holes being configured to align the plurality of pins of the semiconductor device with a plurality of socket pins of a printed circuit board. The housing and the mounting portion include the same insulating material.

Abstract: A Yuga pad of the present invention includes a flexible foaming member with a plurality of reinforced fibers therein. The Yuga pad is made from a raw material mixed with the reinforced fibers and processed by extrusion and vulcanization. In the extrusion step, an extruder will force the reinforced fiber oriented substantially along an axial direction of the extruder. As a result, after vulcanization step the reinforced fibers in the flexible foaming member still are oriented substantially along a direction.

Abstract: A method of making a foamed rubber member includes the steps of: a) Stirring and pressing the foaming raw material repeatedly, wherein the foaming raw material has rubber, an accelerator, and foaming agent mixed in a predetermined ratio. b) Molding the foaming raw material into a meshed rubber sheet. c) Softening a surface of the meshed rubber sheet. d) Resting an attachment on the surface of the meshed rubber sheet and pressing the attachment. e) Vulcanizing and foaming the meshed rubber sheet to have a foaming member.

Abstract: A method of making a hollow foaming member is to utilize the foaming agents with various decomposition speeds or gas issued into the rubber sheet in the die while vulcanization and foaming. As a result, the foaming member made by the method of the present invention has an air cell therein.

Abstract: A cushion has a bottom layer, which is made of a foaming material with a skid-proof capacity, a supporting layer, which is made of an elastic material and molded into a single element, having a first layer attached on the bottom layer, a plurality of supporting posts projected from the first layer and a second layer connected to free ends of the supporting posts, and a top layer, which is made of a foaming material with a skid-proof capacity, attached on the second layer of the supporting layer.
