Laser Measuring Technology in Production of Electronic Assemblies
As delivery chains in Eastern Asia recently are exposed to various problems, many companies in Europe intend to relocate the production of electronics back to Europe. It is a matter of common knowledge however that corresponding restructuring makes good economic sense only in the presence of a high degree of automation. Manual process steps frequently are too expensive.
Nowadays a high degree of automation is usual even for small series in flexible production processes. This means that already at an early stage within the production chain, automatic inspection routines must be implemented, otherwise cost-intensive rework or even product recall may be the consequence.
The production process is subject to the following challenges:
- Ongoing miniaturization of parts complicates more and more manual inspection in very fast production cycles.
- High standards for tested parameters with respect to safety and fitness for purpose of the final product.
- Frequent change of production features and small lot sizes require flexible inspection equipment.
Thanks to the fine resolution and the high testing speed of the QuellTech laser triangulation system, even smallest irregularities can be discovered at an early stage directly inside the production process. The 100% inline inspection enables concerned defective parts to be screened out automatically. Test criteria for the measuring task are specified within the QuellTech Vision Software, which controls and documents the application together with the laser scanner, within the frame of general quality control.
