Use Case: Acoustic inline quality assurance of laser ablation processes

Your challenge

In laser ablation processes used in electronics manufacturing, recycling and component refurbishment, product quality often remains unknown until end-of-line inspection. Variations in layer thickness, material tolerances, component geometries and local material properties can prevent the desired processing result from being achieved despite stable process parameters. Material transitions, residual layers or the onset of over-ablation are often difficult to identify clearly through optical inspection or conventional process parameters. 

Your benefit

Acoustic inline quality assurance captures process sounds without contact and analyses them in real time using signal processing and AI. Material transitions, residual layers, the onset of over-ablation and quality-relevant deviations are detected during laser ablation. This enables direct assessment and documentation of the processing state, reduces scrap and rework, and provides the basis for warnings, automated responses and process control. 

Extras

The solution assesses product quality rather than process parameters alone and operates without optical access, even in the presence of dust, particles and process residues.
