Abstract

The invention relates to a double-station electrical test device, belonging to the technical field of electrical performance test of a semiconductor device. The double-station electrical test device comprises a workbench, an upper detecting plate and a lower detecting plate, wherein a lower detecting table is movably arranged on the workbench; the workbench is provided with at least three groups of conveying assemblies for conveying PCBs; the multiple groups of conveying assemblies are divided to three parts and are equidistantly disposed on the workbench; and the workbench is further providedwith a limiting piece for limiting the PCB right above the lower detecting table. In use, two to-be-detected PCBs are taken to be placed between guiding rods side by side, when the PCB moves right above the lower detecting plate, the limiting piece limits the PCB, the PCB remains at a required position, a first cylinder then drives the lower detecting table to rise to detect the PCB, and thus, two PCBs can be detected at one time, and the effect of improving the detection efficiency can be achieved.

Description

technical field [0001] The invention relates to the technical field of electrical performance testing of semiconductor devices, in particular to a double-station electrical testing device. Background technique [0002] In the production of printed circuit boards, it is necessary to test its electrical properties through jigs. The PCB board test jig is a special fixture designed with the PCB board as a model for on-off testing of electrical properties. It has a single side Cutters and double-sided jigs. [0003] The Chinese patent with the authorized announcement number CN204389642U discloses a PCB board electrical testing fixture, including a base plate and a column arranged on the base plate. The base plate, the first fixing plate, and the second fixing plate are sequentially arranged on the column from bottom to top. and the first guide plate, the first guide plate is provided with a guide post, and the guide post is provided with a spring base plate, a second guide plate...
