Cabinet X-ray device SCIOX SMT
X-ray device the SCIOX SMT is right choice for X-ray check of electronics devices. The main field of X-ray use in electronics production is the check of BGA soldering, measurement of the Voids in BGA balls or check of thermal pads soldering. X-ray can help you to setup the whole soldering process, select correct heating profile and check the correct placement of all components.
With use of the product manipulator you can easily change the magnification of the object. Thanks to online stream you can very fast inspect whole PCB even if it is magnified.
For case, you will need a faster detector, a higher X-ray energy or a higher resolution, we offer the variable solution. The X-ray devices SCIOX can be upgraded in the future. Not only the software, but hardware as well.
The soldering check is not possible to do only with AOI or other optical systems. We are in the future now and the movement brought the miniaturized high power IO packages. It does not have all the pins around the chip, but in most of cases it has pads under the chip. In today’s check, you need to see under the chips to check the soldering. Even the small void on BGA ball can cause the problems in the products. For example, small void on the RAM memory will affect the communication speed between the RAM and the MPU/CPU. Please do not wait until the problems will occurs. You can have a tool to prevent it.
Our technologies for X-Ray SCIOX SMT solution
The X-ray tube is one of the most important component for the X-ray device. It has biggest influence for the quality of captured images and possible magnification. In the SMT field the magnification is very important. The most of components in the SMT is very small and the defects can measure only few microns. X-ray tubes for the SMT field must have as small focal spot as possible. For the SMT is also important variable power and anode voltage (ideal is from 40kV). Some of our tubes can offer up to 240kV. This voltage is very good for bigger components such as chokes or transformers.
The selected X-ray tube has big influence for the quality of the whole X-ray device and thus the use of the device. X-ray tube is one of the most expensive components in the whole devices, so it is very important to think carefully about the right selection. We can offer two kinds three kinds of the X-ray tubes in our devices:
80kV X-ray tube with up to 50µm focal spot is suitable for some basic analysis of soldering. It can be used in application where the inspection of thermal pads is most often inspection. This X-ray source can provide magnification up to 10 times.
160/190/225/240 kV X-ray tube with 2µm focal spot is professional solution for detailed BGA inspection. It can provide the up to 1000x times magnification with the sharp image. This X-ray sources has up to 10W target power.
160/190/225 kV X-ray tube with 0,5µm focal spot is best on the market X-ray tube. It can provide the up to 2500x times magnification with the sharp image. Even the small focal spot you can use up to 25W of the power.

The High-sensitivity X-ray detector can offer very good image quality even the low power X-ray tube (the microfocal spot tube is low power) is used. It can prove high resolution with short scanning time. It is caused by use of CMOS technology, which can provide great sensitivity with low noise output. The Flat panel detectors is large area CMOS image detector which is similar to classic cameras, but with special layer on the chip which will convert X-ray radiation to visible light. These detectors can provide up to 300fps. So, you can see the X-ray image of the objects in the real-time. In the combination of the manipulator, you can easily inspect whole object.
The resolution of the detector can be separated to two groups: spatial and energy resolution.
The spatial resolution is defined by the physical size of the detection elements. For example, we use the flat panels with the 99µm detection elements size. It will say, that the object of 198µm can be detected (the spatial resolution is twice bigger than the detection element size).
The energy resolution is caused by technology of the detector. The CMOS detectors what we use has excellent energy resolution. The basic rule says, the bigger detection elements you have, the better energy resolution you can achieve. With the bigger energy resolution, you can recognize the smaller energy differences in the image. With combination with suitable display you can see some small differences in the material structure such as cracks or small voids. The CMOS detectors, what we use, are very suitable for these applications, because it provides the best energy resolution.
The correct selection of the X-ray detector is not easy and it is very important for the final application. Similar to the X-ray tube it is very expensive component in the whole X-ray device. Our specialist can help you to find the best solution for your application, so please feel free to ask for the help.
In the SCIOX SMT there is the object manipulator for provide easy, fast and detailed inspection of your product. You can easily move the product inside of X-ray not only in X, Y, Z coordinates, but you can rotate it around the axis as well. The combination with the real-time flat panel detector will allows to see the X-ray image during the manipulation of the object. When you will move with object closer to the X-ray source you can magnify the object up to 2500x (based on kind of X-ray tube).
When you want to create the dataset for the X-ray Computed tomography (CT) you will need to use this manipulator. It can rotate the object around the axis during the recording of the data. Then, with use of the Volume Graphics Studio you can reconstruct the 3D model of the object. For example, it can allows to separate the layers of PCB or do the detailed analysis of the BGA connection between the PCB and the ball.
