Damage analysis on faulty assemblies
Finding and correcting defects in realtime: using X-ray inspection we are able to analyse populated and unpopulated multilayer printed circuit boards, power modules, connections such as ball grid arrays (BGA) or quad flat packages (QFN), gullwing pins, integrated circuits (ICs), bonding wires, chips and much more. Thanks to the high speed and the resolution with which the 2D X-ray inspection can be undertaken, damage and defects can be detected and rectified during manufacture. Expensive complaints and recalls are therefore avoided.

Applications of 2D X-ray inspection
Electronics Manufacturing
For the non-destructive inspection of BGA soldered joints, we use automated X-ray inspection (AXI). We analyse the distance between the balls of solder, the solder gradient or joint clearance, verify wetting and dewetting defects and analyse solder joint anomalies, e.g. excess solder, cracks, pores and shrinkage cavities, bridge formation or fractures in the solder joint. 2D X-ray inspection is also used for checking populated and unpopulated multilayer printed circuit boards, power modules, gullwing pins, integrated circuits (ICs) or bonding wires.
Connections and Plugs
We use X-ray inspection for failure analysis and quality control of electrical plug, crimp, and cable connections. The high-resolution X-ray images help identify quality characteristics and material defects and ensure functionality. This non-destructive testing also offers significant advantages for failure analysis, helping to pinpoint the cause of the damage.
Automotive
Industrial X-ray inspection is used during the manufacture of automotive components such as connectors, sensors and electronic control units (ECUs) for the detection of shrinkage cavities, pores, inclusions and other material defects. Industrial X-ray inspection is also used during the non-destructive analysis of battery cells, e.g. during random checks for foreign objects, gas bubbles or metallic inclusions.
Security & Defence
2D X-ray inspection enables fast and non-destructive quality control of safety-critical electronic assemblies and components. Sensors, control electronics, printed circuit boards, and electronic assemblies can be reliably inspected for soldering defects, short circuits, cracks, missing connections, or other hidden defects. This allows manufacturing defects to be detected early on and ensures that the highest quality and safety requirements are met in safety-critical applications.
Frequently Asked Questions
About 2D X-ray Inspection
Here you'll find answers to the most important questions about 2D X-ray inspection.
Both 2D X-ray machines and industrial computer tomographs operate with X-rays. However, during 2D X-ray inspection classic X-ray images are evaluated, while in CT three-dimensional models of the item inspected are prepared.
Automated X-ray inspection (AXI) is used in printed circuit board manufacture to detect and rectify quickly defects on the populated printed circuit board. The high speed during the inspection of the printed circuit boards is possible thanks to the automated image analysis. During this process the 2D X-ray images are evaluated automatically by the system.
Our modern X-ray systems achieve a resolution of up to 0.5 µm. In general this resolution is completely sufficient to detect defects on printed circuit boards or their components. If a higher resolution is required, CT or nano CT is used. Nano CT offers resolutions of up to 0.2 µm, however the process is slower than 2D X-ray inspection.
Detect and evaluate defects quickly and effectively
2d x-ray inspection
2D X-ray inspection uses an X-ray source that emits radiation with a conical pattern toward the item inspected. Radiation that passes through the component is acquired by a detector on the opposite side and the data are converted into an X-ray image. Here it is possible to inspect a very wide range of materials such as metal, ceramic, plastic and composite materials, and even sintered material, solar cells, multilayer printed circuit boards and castings.
Automated X-ray inspection
Automated X-ray inspection (AXI) makes it possible to inspect fully populated printed circuit boards quickly and reliably. The X-ray images are evaluated automatically using a special software application. The high speed makes this method ideal for 100% quality control in series production. The X-rays allow inner structures such as contacts, steps, solder bridges, solder flow, faulty soldered joints or incorrect melting of the solder to be verified.
Planar-CT
Planar computed tomography, planar CT for short, is used if components with a large area or populated printed circuit boards and boards with a complex design are to be analysed using X-rays. Along with a high resolution, this method is distinguished above all by the possibility of depicting a component in several virtual layers without overlapping. For this reason this method is often used during the inspection of multilayer printed circuit boards.
