March, 2024 nScrypt and Sciperio 3D Develop Conformal Heaters


ORLANDO, FL — A recent study conducted by a team in nScrypt’s research arm, Sciperio, demon- strated a significant improve- ment in the performance of con- formal Printed Circuit Struc- tures (PCSs) through the use of novel manufacturing techniques made possible by nScrypt’s high- precision Factory in a Tool. The research focused on im-


proving 3D manufactured conduc- tive traces and vias to increase total yield and tunability of per- formance. These improvements were then practically demonstrated by


printing a circuit with conformal heating elements, which can be used in a wide range of applica- tions, including wearable technolo- gy, heating systems, and electron-


ic devices. The study found that the use

of stacked conductive layers for traces significantly reduced resist- ance compared to single-stacked traces. The resistance steadily dropped as the number of layers increased, reaching a 92% de- crease from layer 1 to layer 7 with- out oven curing, and showing sig- nificantly less resistance than a single layer trace of equal height. The additional height of the stacked trace can be compensated by embedding the trace into the 3D manufactured circuit struc- ture.


In addition, a via fill method


using the nScrypt SmartPump was developed in which via walls were coated with conductive ma- terial using a vacuum extraction technique. The study found that the vacuum evacuation method was effective in connecting 49/50 vias, with an average resistance of 4.8 mW and a standard devia- tion of 0.47 mW. The team applied these de-


velopments in a demonstration PCS that incorporated conformal printed heating elements made possible through stacked traces. The heating elements were printed with varying numbers of stacked conductive layers per section, highlighting the tunabil- ity of resistance without needing


to alter trace widths. Contact: nScrypt, 12151

Reflectors IRVINE, CA — Fairview Mi- crowave has released its new tri- hedral corner reflectors. These specialized devices are engi- neered to excel in radar technol- ogy and antenna testing, offering invaluable solutions for precise testing and measurement appli- cations. The trihedral corner reflec-

tors feature a unique geometry that efficiently reflects incoming signals back toward the source, making them indispensable tools in the fields of radar technology and antenna testing. They are de- signed to optimize signal reflec- tion and measurement accuracy. The compact size of the re-


flectors makes for easy simula- tion of radar targets of various sizes, simplifying testing setups and ensuring precise assess- ments. The reflectors are engi-


neered for high RCS (radar cross-section), enabling precise assessment and calibration of radar systems. They provide a wide operating frequency range of 10 to 100 GHz. The reflectors have a 1/4-20 UNC threaded hole for secure


tripod mounting options. Contact: Fairview Mi-
