Speech Title: Predictive Manufacturing: Subtractive and Additive

Abstract: Manufacturing is the key to today’s industrial competitiveness, and it is broadly classified into two categories, subtractive and additive. In current study, the ability to predictively model manufacturing performance attributes in both categories is introduced. In subtractive manufacturing, modeling of laser-assisted and ultrasonic vibration-assisted milling are presented. In laser-assisted milling, the laser preheating temperature field is predicted, and the dynamic recrystallization as well as grain growth triggered under high temperature is considered, which enhances the accuracy of force and residual stress prediction. In ultrasonic vibration-assisted milling, the intermittent effect is considered through tool-workpiece separation criteria. And the force reduction in ultrasonic vibration-assisted milling is accurately predicted. In additive manufacturing, laser-assisted metal additive manufacturing is introduced. And the predictive modeling of temperature field in powder bed metal additive manufacturing is presented. The model considers heat transfer boundary including heat loss from convection and radiation at the part boundary. Through the comparison between measured and calculated molten pool dimensions, the model is proven to have high computational efficiency and high prediction accuracy.

Speech Title: 3D-Printed mm-Wave Devices and Circuits for System-in-a-Package Applications

Abstract: This invited talk will present our recent research towards strategic design, additive manufacturing (AM also known as 3D printing), and characterization of devices, interconnects and circuits for the emerging mm-Wave and sub-THz system-in-a-package (SiP) applications. This talk begins with a brief overview of our research activities for development of a diverse library of well-characterized functional materials suited for additive manufacturing of mm-W devices, interconnection and packaging of integrated circuits (MMIC’s). The newly developed feedstock composites exhibit promising EM properties (er=4~12 and tandd <0.002) well suited for applications ranging from RF to mmW frequencies (with tested properties up to 110 GHz).
The 3D printed transmission lines and probe pads can be re-rendered to reach µm scale accuracy by laser trimming to facilitate on-package probe testing. The frequency response of a custom-designed distributed amplifier with a fully 3D printed chip assembly have been characterized between 1 GHz and 30 GHz, which exhibit much better wideband performance than an identical QFN-packaged amplifier. On-package probe measurements of a 3D printed microstrip line has exhibited low insertion losses of 0.028 dB/mm at 5 GHz and 0.187dB/mm at 20 GHz, while CPW lines show an insertion loss lower than 0.34 dB/mm at 110 GHz.
This talk also presents a comprehensive study of the design of a multilayer dielectric rod waveguide (DRW), which is comprised of a high permittivity core encased by a low permittivity cladding. The insertion loss of the multi-layer DRW is less than 0.012 dB/mm at Ku-band frequencies and as low as 0.4 dB/mm at WR6 band (110-170 GHz). A dielectric rod antenna (DRA) that consists of a medium permittivity dielectric rod core encased by a low permittivity cladding is also designed to raise the peak gain by 3-9 dB at 30-40 GHz.
