Abstract

The invention is suitable for the technical field of circuit component tests, and provides a detection machine station with a contact impedance detection device, used for detecting a circuit component to be tested. The detection machine station comprises a pressure conduction connecting device, an electric signal supply sensing device and the contact impedance detection device which comprises a set of standard components with known electric characteristics and a set of transfer switches, wherein the transfer switches are used for switching the pressure conduction connecting device to the standard components by electric connection, is provided for the electric signal supply sensing device to sense, and comprises contact impedance of an electric circuit of the pressure conduction connecting device and the standard components.

Description

technical field [0001] The invention belongs to the technical field of circuit component detection, and in particular relates to a detection machine with a contact impedance detection device. Background technique [0002] Since the advent of LED (Light Emitting Diode), compared with traditional light sources, in addition to the advantages of energy saving, low temperature and long life, its efficiency has been greatly improved with the improvement of the production process, and its application fields have become more extensive. A single LED is mostly used such as small Toys, handheld devices and mobile phones, multiple LEDs are often used in lamps, automobiles and traffic signs in daily life. LED manufacturing and quality inspection at various stages are of great significance to ensure the quality of LEDs. [0003] In the process of automatic detection of LED crystals, a structure such as figure 1 The shown pin pressure monitoring sensor (edge ​​sensor) 1 uses a fine probe ...
