With the development of communication technology and the automobile industry, the demand for PCBs has expanded, and they have become an indispensable part of supporting people's comfortable lives.
The X-ray TDI camera enables non-destructive inspection of defects such as voids, cracks, and uneven coating that occur in the soldering of electronic components on the PCB. The C12300 series contributes to the improvement of tact time for in-line inspection by achieving both high sensitivity and high line speed.
For example, in soldering inspection of the back fillet, it is possible to perform a high-speed inspection of defective parts by performing 3D analysis using a brightness profile acquired with high sensitivity.
Lithium-ion batteries (LiB) are used in various fields, including smartphones and electric vehicles.
The X-ray TDI camera enables in-line inspection for defects such as electrode mispositioning and stacking errors inside the LiB. In the case of X-ray inspection using a two-dimensional detector, the image is distorted due to the angle of the X-rays incident on the object, except for the irradiation center of the X-ray source. It may be necessary to adjust the position of each imaging site to perform a precise inspection. On the other hand, the X-ray TDI camera irradiates X-rays perpendicular to the transport direction and integrates the images obtained continuously to perform imaging, so it is possible to obtain images without distortion. This enables in-line precision inspection of large objects.
X-ray TDI camera can inspect the samples easily by high speed scan with narrow irradiate area. S/N ratio is one of advantage and low X-ray radiation is enough to inspect the void existence. Furthermore it contribute to make a smaller size of system by reducing a lot of X-ray irradiation.
Lithium-ion batteries (LiB) and fuel cells are attracting attention as clean energy, and demand is expanding for applications such as automobiles and storage batteries. The X-ray TDI camera enables in-line inspection of minute foreign substances mixed in the sheet material used for batteries.
As an example, with the C12300 series, it is possible to observe 20 μm size SUS pieces mixed in the LiB electrode (negative electrode) in-line.
