Abstract: A probe having a sliding rail is provided and includes a probe head, a probe tail, an elastic element made of an elastic material and connected between the probe head and the probe tail, and a sliding rail assembly. The sliding rail assembly includes a slide rail and a position limit protrusion. The slide rail has a fixed end and a free end. The fixed end is fixedly connected to the probe tail, and the free end extends to the probe head. The position limit protrusion is fixedly connected to the probe head, and has a sliding slot formed thereon through which the slide rail can pass. The sliding rail assembly is made of a conductive material, and a cross-section area of the slide rail is greater than a cross-section area of the elastic material of the elastic element.

Abstract: A probe device of a vertical probe card is provided and includes a die assembly and at least one pin assembly. The die assembly includes a first die, a second die, and a middle die disposed between the first die and the second die. The at least one pin assembly has a first pin, a second pin, and at least one electrical connector. The at least one electrical connector is connected to the first pin and the second pin. The at least one pin assembly is electrically contacted with at least one contact pad of a device under test. The at least one contact pad leans against the at least one pin assembly, so that the at least one pin assembly generates a deformation in a longitudinal direction.

Abstract: A probe structure is provided, including two probe heads for electrically contacting with the two objects, respectively, an elastic buffer portion forming a hollow space therein, a conductive portion being disposed within the hollow space and thereby being surrounded by the elastic buffer portion, and having two ends respectively electrically being connected to the two probe heads. When the two probe heads do not contact with the two objects electrically, the conductive portion is linearly extended between the two probe heads.

Abstract: A support structure located at a bottom of a ball grid array (BGA) is provided. The support structure includes a printed circuit board (PCB) having first positioning pin holes, an interface plate having second positioning pin holes which correspond to the first positioning pin holes arranged on the PCB, a support film arranged on the PCB and having support portions, and positioning components penetrating the first positioning pin holes and the second positioning pin holes corresponding to the first positioning pin holes to assemble the support film on the PCB and the interface plate.

Abstract: A fine pitch interposer structure includes a Multi-core base substrate and a plurality of buildup laminates. A surface of each Multi-core base substrate has a first circuit layer, and a second circuit layer which is electrically connected to the first circuit layer. The buildup laminates are stacked on the surface of the Multi-core base substrate. Each buildup laminate includes a photosensitive dielectric layer, and a plurality of blind vias with a pre-determined interval therebetween which are correspondingly arranged on each of the plurality of vias formed on the photosensitive dielectric layer. The blind vias are electrically connected to the first circuit layer. At least one blind via of one buildup laminate is superimposed on another blind via of another buildup laminate.
