The Benefits of Manual X-Ray Inspection for Medium-Sized Companies


By Astrid Sassen, Head of Marketing, Viscom AG Z


ero-defect strategies and increased demands on PCB assembly production make quality assurance during electronics manufacturing


absolutely critical. Under current conditions, com- pounded by the continuous miniaturization of components, ever-higher board densities and hard-to-view areas, inspection systems are pushed to their limits. X-ray systems are a major but vital


investment for small- and medium-sized companies. They are becomingly increas- ingly worthwhile, as they can be integrated into a wide variety of processes. Flexible, universal X-ray systems are now a necessi- ty for many electronics manufacturers. These X-ray systems can be used in


both manual (MXI) and fully automated (AXI) modes to perform nondestructive test- ing of PCBs, components and assemblies. Their versatility is also making them useful for a wider range of applications.


Batch Size 1 X-ray systems can be used for inspec-


tion of assemblies in series, as well as for random sample inspection. This is often the case for manufacturers evaluating field returns. X-ray systems can be used to check die bonds, BGA and flip chips and voids in soldering. Misalignment of bonding wires with- in an encapsulated component, which can


be caused by the intrusion of casting compound, can also be documented using X-ray inspection. X- ray systems can also inspect THT solder joints, positioning of wedge bonds and unpopulated, mul- tilayer PCBs. Ceramic substrates, as well as classic FR4


PCBs can also be subjected to X-ray quality con- trol. The same applies to plastics, weld seams,


composite materials, etc. Final assembly inspec- tion must not be overlooked, nor measurement of electrical and mechanical end components, such as circuit breakers for the automotive industry. In this example, distances, positions, or dimensions can be analyzed and tracked.


3D CT Reconstruction Viscom offers its X8011-II and X8068


systems for these types of applications. Electronics manufacturers can perform both manual and automated inspection with these systems. The X-ray machines can be used as an offline solution, as well. Inspection results from manual mode


are stored using the live tools. Availability of automatic X-ray analysis and manual or semiautomatic inspection allows the X8011- II and the X8068 to offer a high degree of flexibility. Viscom’s software is specially developed for SMT production, enabling fully automatic analysis, as well as intu- itive, comprehensive analysis, helping oper- ators to check inspection objects quickly and accurately. The company’s proprietary XVR com-


Viscom’s X8068 X-ray systems cover a wide range of inspection requirements and applications.


puted tomography (CT) reconstructs objects in 3D, allowing manufacturers to see defects, volumes and structures recreated in real units of measurement. This optional CT can be used for prototype evaluation, reverse
