Abstract
Description
Technical Field
[0001] This utility model relates to the inspection of electronic components, specifically to a tooling for X-ray inspection of electronic components. Background Technology
[0002] Electronic components are the basic units that make up electronic circuits and electronic devices. They are diverse in type and function and are widely used in consumer electronics, communications, medical and other fields. In the electronics manufacturing industry, X-ray inspection is a core technology for evaluating the internal structural integrity, welding quality and defects of components. It is especially suitable for hidden defects that cannot be observed by the naked eye or optical means.
[0003] Current technologies commonly use trays to place electronic components for X-ray inspection. Traditional tray-fixed component placement only allows for single-view X-ray scanning, making it difficult to cover all defect angles in complex structures. Especially during failure analysis X-ray inspections, single-direction inspections are insufficient to observe minute defects, often requiring multi-angle inspections. A common method involves attaching the component to a foam block or similar object with tape to achieve the desired viewing angle. However, this method has significant drawbacks: firstly, it lacks stability, as the component may not be firmly attached and could detach during observation, necessitating opening the X-ray machine door, reattaching the component, and repeating the inspection; secondly, once the component is attached to the tape, the angle is fixed, preventing further changes to the observation angle, thus failing to effectively address the limitation on viewing angle.
[0004] To address the aforementioned shortcomings of existing technologies, this invention proposes a fixture for X-ray inspection of electronic components that is widely applicable, easy to operate, and capable of multi-angle inspection. Using this invention ensures that the inspected device remains firmly fixed on the test station throughout the multi-angle X-ray inspection process, thereby effectively improving the stability of the inspection. Utility Model Content
[0005] The purpose of this invention is to provide a tooling for X-ray inspection of electronic components that is widely applicable, easy to operate, and capable of multi-angle inspection of the inspected devices.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A fixture for X-ray inspection of electronic components includes a base plate, characterized by a pair of supports symmetrically arranged at the left and right edges of the base plate, with a rotating shaft sleeved on each support. An arc-shaped transmission block is fixed to the middle of the rotating shaft, and meshing teeth and a connecting plate are respectively provided at the bottom and top of the arc-shaped transmission block. A drive adjustment assembly is fixed to the middle of the base plate, comprising a frame, a toothed plate, a screw, and a first knob. The front of the frame has a through hole, and the toothed plate has a threaded hole. The front part of the screw engages with the threaded hole to move the toothed plate back and forth along the frame, and the tail end of the screw passes through the through hole and connects to the first knob. A placement frame is fixedly connected to the connecting plate, and the placement frame includes a horizontal plate and components respectively fixed to the horizontal plate. The vertical plates at both ends of the plate and the horizontal plate have strip-shaped through holes in the middle along the long side. The two vertical plates are respectively sleeved on both ends of the bidirectional lead screw. One end of the bidirectional lead screw passes through the vertical plate and is connected to the second knob. The clamping assembly includes a left slider, a right slider, a left shelf, and a right shelf. The left slider is provided with a left sliding groove and a left-hand threaded through hole, and the right slider is provided with a right sliding groove and a right-hand threaded through hole. The left shelf and the right shelf are respectively connected to the top of the left slider and the right slider. The left slider and the right slider are screwed to the bidirectional lead screw through the left-hand threaded through hole and the right-hand threaded through hole, respectively. The left sliding groove and the right sliding groove are respectively engaged with the strip-shaped through hole. The meshing teeth are engaged with the toothed plate. The left shelf and the right shelf form the work station for the inspected device.
[0008] Furthermore, the clamping assembly also includes a left pressure spring and a right pressure spring. One end of the left pressure spring is fixed to the top of the left slider, and the overhanging end of the left pressure spring contacts the left shelf. One end of the right pressure spring is fixed to the top of the right slider, and the overhanging end of the right pressure spring contacts the right shelf.
[0009] Furthermore, the left and right sliders are symmetrically screwed onto the bidirectional lead screw.
[0010] Furthermore, the base plate has a rectangular plate structure, and suction cups are provided at the four corners of the bottom surface of the base plate.
[0011] The working process of this utility model is as follows:
[0012] Place the device under inspection horizontally in the device under inspection station of this invention. Rotate the second knob to bring the left and right sliders closer together to clamp the device under inspection, and press them down with the left and right pressure springs. Then, place this invention into the X-ray inspection machine and close the machine door. Next, inspect the device in the Y direction. If no abnormalities or defects are observed, the device is qualified. Open the X-ray inspection machine door and remove the device. The test is complete. If abnormalities or defects are observed, further X-ray inspection is required.
[0013] Open the X-ray inspection machine door, first turn the first knob to rotate the device under inspection to the desired observation angle, then close the X-ray inspection machine door; then, perform an X-ray inspection. If the defects and location information of the device under inspection can be confirmed, the inspection is complete; if the defects and location information of the device under inspection cannot be confirmed, a Z-ray inspection is required.
[0014] Open the X-ray inspection machine door, take out the present invention, remove the device under inspection, rotate it 90° and then reassemble it, put the present invention into the X-ray inspection machine, and close the X-ray inspection machine door; then, perform Z-direction inspection until it is confirmed whether the defect exists and the location of the defect inside the package, etc., to provide a basis for subsequent testing.
[0015] This invention is applicable to components of various packaging forms and sizes. It is easy to operate and enables comprehensive, multi-angle observation of the inspected device, which is particularly beneficial for quickly and accurately locating defects in failure analysis. Using this invention, the inspected device is ensured to remain firmly fixed on the test station throughout the entire X-ray inspection process, thereby effectively improving the stability of the inspection.
