Nano Dimension Ltd. has developed 3D printed capacitors with the company’s DragonFly additive manufacturing system. These capacitors are embedded in the body of the additively manufactured printed circuit boards (PCBs), saving space and eliminating the need for assembly, the company reports. This type of additive manufacturing of electronics validates the manufacturing applicability of built-in capacitors in PCBs printed with the DragonFly system.
Nano Dimension’s testing with capacitors of different 3D dimensions have shown consistent results with statistically validated data. The repeatability results show less than 1% variance. The technology uses the same dielectric and metal traces as in the additively manufactured PCB yielding capacitors with a capacitance range from 0.1nF to 3.2nF. The successful results are based on over 260 tests with 30 different additively manufactured capacitors dimensions.
Capacitors of this kind are primarily used to filter electrical noise and ripple voltage for a wide range of applications, including RF transmission lines, audio processing, radio reception and power circuit conditioning.
“The test results clearly show that with the DragonFly system our customers can achieve repeatability comparable to that of traditional processes in short run manufacturing of capacitors using 3D printing,” says Amit Dror, CEO of Nano Dimension. “Along with high accuracy, miniaturization and space saving on the board, these are key factors in the electronics production process and next generation electronics applications.”
