Problems solved by technology
[0003] Especially in the manufacture of printed circuit board assemblies, it is customary to inspect the printed circuit board assembly manually. The manual visual inspection method is to let the inspector support the printed circuit board assembly with his hands, and then flip and rotate the printed circuit board assembly back and forth to make the printed circuit board assembly The board assembly is at various angles to inspect the parts of the printed circuit board assembly. If the inspector needs to inspect a certain part, he must exert pressure on the printed circuit board assembly, but the printed circuit board assembly will not be properly supported. The solder balls are broken, which in turn causes damage to the printed circuit board assembly, which not only causes damage to the printed circuit board assembly, but the inspector is prone to fatigue due to the long-term inspection of the printed circuit board assembly in the above-mentioned way, which leads to a decrease in the detection rate and finally causes production failure. reduced quality
[0004] In order to solve the above problems, a support jig will be provided in the future to cooperate with the visual inspection operation, so that the printed circuit board assembly has an appropriate support force, which can prevent the deformation of the printed circuit board assembly or the cracking of the solder balls, but the support jig must be supported by manpower and Flip and rotate back and forth, and the weight of the supporting fixture is quite heavy, the inspectors are quite strenuous to use, and their physical strength is consumed faster than usual, and they are prone to fatigue

Embodiment Construction
[0018] In order to enable the examiner to have a further understanding and understanding of the structural features and the achieved effects of the present invention, I would like to provide a preferred embodiment and a detailed description, as follows:
[0019] see figure 1 , is a perspective view of a preferred embodiment of the present invention; as shown in the figure, this embodiment provides a fixing device for detection, which is mainly used for visual inspection, and the fixing device 1 fixes and supports a test piece 2, Flip and rotate the DUT 2 to form various detection angles, so that the user can detect the light reflection state of the DUT 2 at various detection angles, wherein the DUT 2 is a printed circuit board assembly , the general printed circuit board assembly has a central processing unit, and its surface has a protective cover. When the protective cover is opened, because the fixing device 1 gives the DUT 2 an appropriate supporting force, it is less like...

The invention relates to a fixing device for detection. The fixing device comprises a pedestal, a movable mechanism and a support plate, wherein the movable mechanism is arranged on the pedestal; the support plate is arranged on the movable mechanism and supports a member to be detected; and the movable mechanism enables the support plate to overturn and rotate, and the support plate drives the member to be detected to overturn and rotate to detect the member to be detected from various angles. The fixing device allows the member to be arranged and supported, so a user can detect the member to be detected from different angles without any manpower support, thereby the excess fatigue of the user is avoided, the assembly damage of the member to be detected in the detection process is prevented, the cost is effectively reduced, and the production benefit is improved.
Description
technical field [0001] The invention relates to a fixing device for testing, in particular to a fixing device for fixing a test piece without manpower. Background technique [0002] At present, in the manufacture of electronic components, in order to maintain the overall quality, it is necessary to check whether each electronic component is normal during the manufacturing process. In this way, when these electronic components are assembled, the overall pass rate will be improved. Of course, after the electronic components are assembled, it will also be It must be checked for correct assembly or damage. [0003] Especially in the manufacture of printed circuit board assemblies, it is customary to inspect the printed circuit board assembly manually. The manual visual inspection method is to let the inspector support the printed circuit board assembly with his hands, and then flip and rotate the printed circuit board assembly back and forth to make the printed circuit board ass...
