Aerosol Jet Printing (AJP) and Directed Energy Deposition (DED) 3D printer developerOptomechas released its latest electronics 3D printer: the Aerosol Jet HD2.
Optomec’s new system still allows users to print interconnects onto 3D substrates, only now with a higher level of precision and throughput than before. The HD2 is also capable of fabricating circuit boards with better high-frequency performance, lending them potential signalrelaying or automotive radar applications.
“HD2真的改变了设计师的思维方式about IC packaging,” said Bryan Germann, Aerosol Jet Product Manager. “Not only can it reduce the size of the final electronics package, but it also out-performs wire bonding when it comes to high-frequency signals. Wire bonds simply produce a lot of inductance above 40 GHz.”
Optomec’s AJP 3D printing portfolio
随着HD2的推出，该公司现在生产了四台不同的AJP机器，包括Flex，5X和Theoriginal HD.Aerosol Jet Printingis one of Optomec’s two main printing technologies, and it’s largely used to create interconnects between 3D substrates inside devices such as LED chips or stacked die.
During the AJP process, Optomec’s systems spray nanoparticle-based inks onto either a 2D or 3D surface, which are then sintered together.该技术消除了对传统电线键合的需求，其与导电金，银的兼容性既借出了航空航天和消费电子产品。
Samsung Electronics, for instance, has installedOptomec’s AJP 5X system, as a means of accelerating its electronics production process.Elsewhere, AJP has been used to create everything fromhigh-resolution circuits和具有集成传感器的涡轮刀片, towireless Bluetooth transceivers.
去年,研究人员从全球国防冷杉m诺斯罗普·格鲁曼（Northrop Grumman）even built on Optomec’s technology todevelop anew method of 3D printing uprgraded semiconductors.Now, with the launch of its new machine, Optomec has refined the AJP process itself, as a means of better addressing the potentially lucrative semiconductor market.
The new Aerosol Jet HD2 machine
Optomec’s new system is designed to allow users to create complex electronics, that drive better performance from 5G-capable devices. As a result, the HD2 has been built with a focus on precision, and it’s capable of printing features just 10 microns wide, significantly better than the 20 microns possible with the original.
像其AJP前任一样，HD2可用于打印到2D或3D基板上，并且其对多个墨水输入设备的支持意味着可以在打印过程中切换材料。Optomec的新机器还与导电金属以及一些dielectric polymers, enabling the production of复杂的电子设备，例如传输线，传感器或天线。
Dimensionally, weighing in at 567kg and standing 2185mm tall, the HD2 is larger and lighter than its predecessor, while its 300 x 300 x 100mm print area is wider too. Connectivity-wise, the new machine also features USB 3.0 and RGB LED ports, allowing users to customize it with whichever lighting accessories take their fancy.
Other optional extras for the HD2 include a rotate table for 4-axis processing, and an in-line conveying option that enables automated loading, and higher-volume manufacturing. Finally, new adopters also receive the firm’s proprietary software, which guides users through their initial set-up, and ensures QA compliance.
