AT&S Make Cars Fit for the Transport of Tomorrow


Reading time ( words)

For vehicles to operate as autonomously as possible in the future, they must meet completely new requirements in data processing and sensor technology. State-of-the-art technology by AT&S enables high-resolution scanning of the surroundings as well as processing and transferring the data volume incurred. In January, the high-tech group from Austria will present its latest developments in this area at the CES Consumer Electronics Show.

Cars that operate autonomously and without errors are a cornerstone of concepts aiming to make transport greener and safer. From today’s perspective, this is still a distant dream as the technical challenges are enormous and legal framework conditions are yet to be established. Autonomous vehicles permanently need accurate information about their surroundings, sufficient computing power to process this flood of data and high-speed data connections to communicate with traffic lights or other cars. As the share of electronics in cars increases, little space is available and miniaturisation is continuously gaining importance.

Sensors for Cars

AT&S has developed solutions that all leading automotive manufacturers use to cope with these challenges: For example, new processes allow the integration of antennas for high-frequency signals directly into printed circuit boards with virtually no losses. This allows building radar sensors featuring significantly higher resolution than current products. As a result, self-driving cars of the future will be able to reliably identify small objects such as small animals or things on the road.

Likewise, high-resolution cameras are used to collect reliable information about the surrounding environment. AT&S benefits from its long-standing experience in the smartphone market, which enables us to integrate high-resolution optical sensors directly into the printed circuit boards. As a result, extremely robust systems are created which can identify pedestrians or road conditions very quickly since the data can be processed directly in the camera module.

V2X Communication

In order for self-driving cars to capitalise on their advantages, coordination between them will be necessary. The data collected by a vehicle must be shared with other road users. Moreover, traffic lights or toll booths also have to pass on information to vehicles. This requires wireless communication channels that transmit data with high bandwidth and without delay. The new 5G standard meets these requirements. With its HDI and substrate-like printed circuit boards (SLP), AT&S provides the basis for such complex communication channels which meet even the highest demands very efficiently.

The less human intervention is intended, the more complex the decisions that need to be made by driver assistance systems for self-driving cars. Different processors and processing units that operate reliably and fast are required for general and specialised tasks. AT&S interconnect solutions combine the necessary data processing capacity and computing power in a very small space while at the same time meeting the demanding automotive requirements.

AT&S at the CES Las Vegas

AT&S will be presenting these and many other solutions for the first time at one of the world’s most influential technology events – the Consumer Electronics Show in Las Vegas. Visit us from January 5 to 8, 2022 at our booth #51134 in the Austria Pavilion (Venetian Expo (formerly Sands), Level 2, Halls A-C) and find out everything about how AT&S is helping to shape the future.

Test and Inspection: Competitive Advantage and Cost of Doing Business

12/08/2021 | Nolan Johnson, I-Connect007
In this interview, Charlie Capers of Zentech breaks down the changing requirements he’s seeing in test and inspection in the industry, and the growing importance of investing in testing for the future growth and success of your company. According to Capers, "When you collect statistics on defects, you will start to see a trend that says, for example, we’ve got a lot of shorts and opens, meaning that our solder paste process is not tight. If you’re collecting statistics and really studying them, you will see trends in your processes."

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

12/03/2021 | Andy Shaughnessy, I-Connect007
It hardly feels like the end of 2021, but here we are, looking at a new year and IPC APEX EXPO and AltiumLive coming up in less than two months. If you don’t count days lost during the holidays, it’s more like one month before showtime. Hey, at least we have some live events to attend now. This week, we have some association and trade show news, as well as articles on data management and the diminished role of U.S. chip makers in the global electronics supply chain. We’re almost behind the eight-ball here, folks, and we can’t build chip factories overnight. Let’s get a move on!

New Methods for Quantifying PCB Design Weaknesses and Manufacturing Challenges

Gerry Partida explains, "The industry is at a new point in evolving how we look at building boards. Our industry has historically built boards and then tried to find a test for them. Then, when they found a test for it, they figured out that it needed to be analyzed before they built the board. We did this with electrical test. We built boards and down the road, as people started asking, “Why am I buying bad boards? We should electrically test them,” electrical test was introduced, reluctantly, into the test part of manufacturing printed circuit boards by suppliers or fabricators. Then they embraced it. But when we started testing boards, we did comparison tests."
