Abstract

The invention relates to a fixing device and particularly relates to a PCB fixing device facilitating PCB detection. According to the PCB fixing device facilitating PCB detection, an external light source can be shielded, a PCB can be clamped, and the position of the PCB can be conveniently adjusted. The PCB fixing device facilitating PCB detection provided by the invention comprises a fixing mechanism on which a translation mechanism is arranged; a placing plate which is arranged on the translation mechanism; and a limiting plate which is arranged on one side of the placing plate. A clamping plate can clamp a PCB, a worker tightens a fan-shaped ring by twisting a bolt to fix a supporting seat on a frame of an observation instrument, the worker can conveniently use the instrument to detect the PCB, and the worker can enable the PCB to move to a proper position to be detected by pushing a first square sliding rod and a second square sliding rod.

Description

technical field [0001] The invention relates to a fixing device, in particular to a PCB board fixing device which is convenient for PCB board detection. Background technique [0002] PCB inspection typically measures impedance characteristics between test points to detect any continuity. It can be mainly divided into two categories: visual test method and electrical test method. Visual testing determines whether a board is acceptable by visual inspection by an operator using a magnifying glass or a calibrated microscope and determines when corrective action is required. Electrical performance testing is the process of identifying manufacturing defects and testing analog, digital and mixed-signal components to ensure they meet specifications. [0003] The main advantage of the traditional visual test method is that the initial cost is low, but there is no test fixture. When testing the PCB board, it is generally placed on the table manually and the instrument is used to tes...
