Abstract

The invention provides a separation testing method of a pixel of an electric testing point and a testing device thereof. The separation testing method of the pixel of the electric testing point comprises the steps of: providing a testing plate which comprises a conductive layer and a glass base plate; operating a row loop and a line loop for controlling the electric conductivity of a pixel contact of the conductive layer; providing at least one electric element; forming a first circuit layout by the electric testing point of the electric element; forming a preset gap between the electric testing point of the electric element and the pixel contact of the testing plate; providing a control module for operating the row loop and the line loop of the conductive layer; enabling the pixel contact to form a second circuit layout; providing an alignment procedure; enabling the second circuit layout to correspond to the first circuit layout; and operating a testing procedure for testing the first circuit layout.

Description

technical field [0001] The present invention relates to a test device and a test method, in particular to a test device and a test method applied to semiconductor elements or printed circuit boards. Background technique [0002] In the past, in the process of testing related electrical components such as printed circuit boards or semiconductor components, different electrical components have different electrical measuring points with different circuit layouts, so test fixtures often need to be replaced with different circuit layouts or electrical measuring points. Or adjust the position and spacing of the probes in the test fixture, so that the probes of the test fixture can be accurately aligned to the electrical measuring points of the electrical components, so as to facilitate the subsequent testing of the electrical components. However, the above-mentioned processing method is time-consuming and greatly affects the test cost. Therefore, how to improve the structure and t...
