Hanwha Launches Modular Component Mounters at APEX


Cypress, CA — Hanwha, formerly Samsung C&T Automation, commem- orated the induction of its HM520


modular component mounter at a rib- bon cutting ceremony that took place Tuesday, January 29, at IPC APEX


Expo in San Diego, California. The MH520 modular mounter was also given a prestigious NPI award at the show in the category of “Component Placement — High-Speed.” “Hanwha’s HM520 advanced


modular component mounter deliv- ers industry-leading price-perform- ance with unprecedented low costs of operation and ownership,” comment- ed Jonny Nichols, director of sales

Sustainable 3D-Printed Electronic IoT Sensors


Surrey, British Columbia, Canada — Simon Fraser University (SFU) and Swiss researchers are developing an eco-friendly, 3D-printable solution for producing wireless Internet of Things (IoT) sensors that can be used and disposed of, without con- taminating the environment. Their research was published in the jour- nal Advanced Electronic Materials. SFU professor Woo Soo Kim is

Addi- tionally, 3D printing can offer the flexibility to add or embed functions onto 3D shapes or textiles, creating greater functionality. “Our eco-friendly 3D printed


cellulose sensors can wirelessly transmit data during their life, and

Keener Eyesight for Autonomous Vehicles


Cambridge, MA — Autonomous vehi- cles relying on light-based image sen- sors often struggle to see through blinding conditions, such as fog. But MIT researchers have developed a sub-terahertz-radiation receiving sys- tem that could help steer driverless cars when traditional methods fail. Sub-terahertz wavelengths,

which are between microwave and in- frared radiation on the electromagnet- ic spectrum, can be detected through fog and dust clouds with ease, where the infrared-based LiDAR imaging systems used in autonomous vehicles struggle. To detect objects, a sub-tera- hertz imaging system sends an initial signal through a transmitter; a receiv- er then measures the absorption and reflection of the rebounding sub-tera- hertz wavelengths. That sends a sig- nal to a processor, which recreates an image of the object. But, implementing sub-terahertz


sensors into driverless cars is chal- lenging. Sensitive, accurate object- recognition requires a strong output baseband signal from receiver to processor. Traditional systems, made of discrete components that produce such signals, are large and expensive. Smaller, on-chip sensor arrays exist, but they produce weak signals. In a paper published in the


IEEE Journal of Solid-State Cir- cuits, the researchers describe a 2D, sub-terahertz receiving array that is orders of magnitude more sensitive, meaning it can better capture and in- terpret sub-terahertz wavelengths in the presence of a lot of signal noise.
