Non-destructive component inspection

Cost-effective 2d x-ray method for serial inspection

2D X-ray inspection is excellently suited to quick, reliable quality control during the series production of high-quality semiconductor and electronic components, as well as other components. The method is not only particularly cost-effective, it also makes it possible to check the areas that remain hidden to normal optical inspection systems.

We support you with non-destructive analyses as per the acceptance criteria for electronic assemblies (IPC-A-600) and printed circuit boards (IPC-A-610). Fixed and mobile ESD protection zones as well as certified personnel are available for the inspection of components sensitive to electrostatic.

2D X-ray system for inspection and analysis

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.

Detecting and rectifying 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 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.

Applications for 2d x-ray inspection

Industrial X-ray inspection is used in a very wide range of sectors. The focus is always on the non-destructive inspection of internal and external structures, the analysis of soldered joints and defect analysis. Listed in the following are applications of importance for us:

Analyses for e-mobility

Automotive und Mobility

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.

Semiconductor industry

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 connectors

We use X-ray inspection for defect analysis and quality control on electrical connectors, crimped connections and cable connections. The high-resolution X-ray images help to identify quality features and material defects and to safeguard the functionality. Non-destructive inspection also offers significant advantages for locating the cause of the damage during damage analysis.

Consumer electronics

Quick, cost-effective analyses are a major advantage particularly for random, small batch and 100% inspections. In the area of consumer electronics, quality control for sensors plays a major role. Here we analyse material structures inside the component and verify the quality of the soldered joints.

Frequently asked questions

What is the difference between 2d x-ray inspection and industrial computed tomography?

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.

What is automated x-ray inspection?

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.

What resolution is achieved by 2d x-ray inspection?

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.
