“…To pattern the conductive traces and ground plane of the CPW, a 60-µm thick PET tape is laser-cut by the LPKF Protolaser U4 to create a stencil of the CPW, which is placed on the substrate, as shown in [34]. The LPKF Protolaser U4 uses a 355-nm wavelength UV laser with a ∼20-µm diameter focus, which enables the micro-machining of the PET tape to create the PET stencil without damaging the substrate below.…”

Additive manufacturing (AM) enables the development of rapid, low-cost prototypes for adhoc and on-demand manufacturing to repair and keep up the continuous operation of systems, especially in time-sensitive scenarios where the system recovery cannot wait for the shipment of new components. Therefore, the industry, military, and academia continue to invest in these technologies to potentially achieve novel 3D geometries based on high-temperature dielectric and conductors to endure harsh environments, such as commonly found in the oil and gas, defense, and aerospace sectors. This paper reports the electromagnetic properties of 3D-printed Yttria-Stabilized Zirconia (YSZ) for 2-6 GHz and the DC and RF effective conductivity of sintered platinum ink, where the dissipative losses of the additively manufactured coplanar waveguides (CPWs) are less than 0.05 dB/mm when the frequency is below 4 GHz. In addition, the AM CPWs are exposed to thermal cycling up to 600 • C to study the material's thermal fatigue and potential degradation. However, the samples do not exhibit appreciable degradation after thermal cycling. Also, a two-layer back-fed antenna based on 3D-printed YSZ and platinum ink is designed, manufactured, and tested. Results show a measured gain of 2.5 dBi and a front-back ratio of 9.6 dB at 4.1 GHz.

“…Therefore, 3D printed electronics offer customizable electronic components in 3D space with reduced lead time and inventory in a less expensive-especially for low production runs-yet more streamlined manufacturing process [15][16][17]. To date, 3D printed electronics have been demonstrated in various forms including antennas, embedded electronics, smart devices, structural/health monitors, electronic textiles, and other passive electronic elements including RFID tags, coplanar waveguides, and capacitors [4,[18][19][20][21][22][23][24][25][26][27][28][29][30][31].…”

The ability to fabricate functional 3D conductive elements via additive manufacturing has opened up a unique sector of ‘hybridized printed electronics’. In doing so, many of the rigid standards (i.e., planar circuit boards, potting, etc.,) of traditional electronics are abandoned. However, one critical challenge lies in producing robust and reliable interconnections between conductive inks and traditional hardware, especially when subjected to harsh environments. This research examines select material pairings for the most resilient interconnection. The method of test is wire bond pull testing that would represent a continuous strain on a connection and high acceleration testing of up to 50,000 g that would represent a sudden shock that electronics may experience in a drop or crash. Although these two environments may be similar to an overall energy exerted on the connection, the rate of force exerted may lead to different solutions. The results of this research provide insight into material selection for printed electronic interconnections and a framework for interconnection resiliency assessment, which is a critical aspect in realizing the production of next generation electronics technologies for the most demanding environments.
