This paper describes a process for batch manufacturing, assembly, and packaging of metal alloy microrelays directly on printed circuit board (PCB) substrates for high-power radio frequency (RF) applications. Stainless steel cantilevers with Pt-Rh tips are mounted on Rogers 4003 PCB substrates to demonstrate the approach. A multilayer PCB design allows for the use of subsurface metal layers to transmit...
This paper reports a method for integrating and micromachining spherical structures made from materials such as fused quartz that are not amenable to melting or reflow. The 3D-SOULE process combines batch-mode micro ultrasonic machining (μUSM), lapping, and micro electro-discharge machining (μEDM) for creating spherical structures. Micro electro discharge machining is used for creating the stainless...
This paper describes recent advances in batch-mode micro ultrasonic machining (??USM) and its application to quartz crystal (QC) microstructures. Acoustic emission sensors are used for close monitoring of this batch process. Multi-level AT-cut QC microstructures have been successfully fabricated at a cutting rate >24 ??m/min, which is substantially faster than available options for plasma-based...
