Seam Sealing of Electronic Packages Using Pulsed Laser Sources

To protect sensitive electronic components from contaminants seeping in and to ensure safe and reliable operation, the components’ housing must be sealed hermetically. Using a laser source as a tool provides high welding speeds and produces fine welding seams with narrow welding radiuses….

Precision Motion Control for Lasers Processing

Recent successes in laser processing come down to a tandem of progression in ultra-short pulse laser technologies, motion control and industrial automation. In order to direct the laser beam precisely to where its energy is needed, either the beam can…

Configuring Sample Stages

The precise and fast movement of the sample or the objective play a crucial role for achieving good results when working with light microscopes. The demands on stages and scanners are manifold. In addition to the position resolution, which…

Fully-Automated Testing of Silicon Photonics at Wafer Level

The integration of photonic structures or elements (e.g. waveguides, laser and photodiodes, multiplexer) on a silicon chip presents, already at wafer level, a multitude of new challenges for the testing technology of these elements. In order to transmit the…
