(レーザー関連)Laser Processing of Metal-Plated Brittle GaN Ceramic Substrates

Demanding electronics applications can be realized with the LPKF ProtoLaser R4

Gallium nitride (GaN) substrates can be used in power interconnects and radio-frequency electronics for wireless communications. In the development of power electronics, they are increasingly being considered as substitutes for silicon-based chips and circuits. Application areas include 5G, defense and commercial aerospace, and satellite communications. However, processing of metal-plated gallium nitride-based ceramic materials can be challenging if the materials are composed of thin conductive metal layers on thick brittle ceramic substrates and both must be processed by machine.
