Improving Laser Seam Welding Performance
Featured Product from PI (Physik Instrumente) L.P.
Improving Laser Seam Welding Performance for Electronic Packages
Increase throughput, performance by combing linear stages with Galvos and PI controllers/software
Sensitive electronic assemblies and micro-systems are sealed hermetically to increase lifetime and performance. Laser seam welding is the preferred process to allow very accurate seams with small radii. Laser welding reduces thermally or mechanically induced stress in the housing and provides higher process speed, compared to conventional welds. The use of a laser galvo scanner head provides additional control features, such as controlling and expanding the laser’s effective fine spot size to the seam width, by creating a complex welding pattern that is overlaid with the path provided by the motorized stages to create higher quality welds while increasing throughput, and taking advantage of higher power laser sources. Coordinating galvos with motion stages for the best results, is made easy with latest software, motion hardware and motion controllers from PI.
