Raspberry Pi Cuts Product Returns By 50% By Changing Up Its Pin Soldering

SlashDot - mer, 04/30/2025 - 17:00
An anonymous reader quotes a report from Ars Technica: Raspberry Pi boards have a combination of surface-mount devices (SMDs) and through-hole bits. SMDs allow for far more tiny chips, resistors, and other bits to be attached to boards by their tiny pins, flat contacts, solder balls, or other connections. For those things that are bigger, or subject to rough forces like clumsy human hands, through-hole soldering is still required, with leads poked through a connective hole and solder applied to connect and join them securely. The Raspberry Pi board has a 40-pin GPIO header on it that needs through-hole soldering, along with bits like the Ethernet and USB ports. These require robust solder joints, which can't be done the same way as with SMT (surface-mount technology) tools. "In the early days of Raspberry Pi, these parts were inserted by hand, and later by robotic placement," writes Roger Thornton, director of applications for Raspberry Pi, in a blog post. The boards then had to go through a follow-up wave soldering step. Now Pi boards have their tiny bits and bigger pieces soldered at the same time through an intrusive reflow soldering process undertaken with Raspberry Pi's UK manufacturing partner, Sony. After adjusting component placement, the solder stencil, and the connectors, the board makers could then place and secure all their components in the same stage. Intrusive reflow soldering this way involves putting solder paste on both the pads for SMD bits and into the through-hole pins. The through-hole parts are pushed onto the paste, and the whole board then goes into a reflow oven, where the solder paste melts, the connectors fall in more fully, and joints are formed for all the SMD and through-hole parts at once. You can watch the process up close in this mesmerizing video from Surface Mount Process. Intrusive reflow soldering is not a brand-new process, but what it did for the Raspberry Pi is notable, according to Thornton. The company saw "a massive 50% reduction in product returns," and it sped up production by 15 percent by eliminating the break between the two soldering stages. By removing the distinct soldering bath from its production line, the company also reduced its carbon dioxide output by 43 tonnes per year (or 47.4 US tons).

New Atomic Fountain Clock Joins Elite Group That Keeps the World on Time

SlashDot - mer, 04/30/2025 - 16:01
NIST: Clocks on Earth are ticking a bit more regularly thanks to NIST-F4, a new atomic clock at the National Institute of Standards and Technology (NIST) campus in Boulder, Colorado. This month, NIST researchers published a journal article establishing NIST-F4 as one of the world's most accurate timekeepers. NIST has also submitted the clock for acceptance as a primary frequency standard by the International Bureau of Weights and Measures (BIPM), the body that oversees the world's time. NIST-F4 measures an unchanging frequency in the heart of cesium atoms, the internationally agreed-upon basis for defining the second since 1967. The clock is based on a "fountain" design that represents the gold standard of accuracy in timekeeping. NIST-F4 ticks at such a steady rate that if it had started running 100 million years ago, when dinosaurs roamed, it would be off by less than a second today. By joining a small group of similarly elite time pieces run by just 10 countries around the world, NIST-F4 makes the foundation of global time more stable and secure. At the same time, it is helping to steer the clocks NIST uses to keep official U.S. time. Distributed via radio and the internet, official U.S. time is critical for telecommunications and transportation systems, financial trading platforms, data center operations and more.

Finland Restricts Use of Mobile Phones During School Day

SlashDot - mer, 04/30/2025 - 12:51
Finland has passed legislation to restrict the use of phones and other mobile devices during the school day amid fears over their impact on student wellbeing and learning. From a report: Under the changes, which were approved by the Finnish parliament on Tuesday and will come into effect on 1 August, mobile devices will be heavily restricted during lesson times. Pupils will be allowed to use them only with the teacher's permission for healthcare or learning purposes. Finland is the latest European country to impose legal restrictions on the use of phones and other mobile devices in schools amid growing evidence of their impact on children and young people, including attention and self-esteem. Earlier this year, Denmark said it would ban mobile phones from all schools. The chair of the country's wellbeing commission, Rasmus Meyer, told the Guardian the measure was necessary to stop schools from being "colonised by digital platforms" and urged the rest of Europe to follow suit.

Google's Sundar Pichai Calls US Remedies 'De Facto' Spinoff of Search

SlashDot - mer, 04/30/2025 - 12:02
Alphabet CEO Sundar Pichai told a judge who found that Google illegally monopolizes online search that a Justice Department proposal to share search data with rivals would be a "de facto" divestiture of the company's search engine. From a report: If Google were required to share both its search data and the information on how it ranks results, rivals could reverse engineer "every aspect of our technology," Pichai testified on Wednesday. "The proposal on data sharing is so far reaching, so extraordinary," Pichai said. It "feels like de facto divestiture of search" and its entire intellectual property and technology over 25 years of research, he said. During testimony in federal court in Washington, Pichai asserted that a package of antitrust remedies proposed by the government is too extreme and will undermine Google's ability to compete in the market.

Chemical In Plastics Linked To 350,000 Heart Disease Deaths

SlashDot - mar, 04/29/2025 - 23:30
An anonymous reader quotes a report from The Hill: Daily exposure to certain chemicals used to manufacture household plastics may be connected to more than 356,000 cardiovascular-related deaths in 2018 alone, a new analysis has found. These chemicals, called phthalates, are present in products around the world but have particular popularity in the Middle East, South Asia, East Asia and the Pacific -- regions that collectively bore about 75 percent of the global death total, according to the research, published on Tuesday in the Lancet eBioMedicine. Phthalates, often used in personal care products, children's toys and food packaging and processing materials, are known to disrupt hormone function and have been linked to birth defects, infertility, learning disabilities and neurological disorders. The NYU Langone Health team focused in the analysis on a kind of phthalate called di-2-ethylhexyl phthalate (DEHP), which is used to make items like food containers and medical equipment softer and more flexible. Scientists have already shown that exposure to DEHP can trigger an overactive immune response in the heart's arteries, which over time can be linked to increased risk of heart attack or stroke. In the new analysis, the researchers estimated that DEHP exposure played a role in 356,238 global deaths in 2018, or nearly 13.5 percent of heart disease mortality among men and women ages 55 through 64. [...] These findings are in line with the team's previous research, which in 2021 determined that phthalates were connected to more than 50,000 premature deaths each year among older Americans -- most of whom succumbed to heart conditions. But this latest analysis is likely the first global estimate of cardiovascular mortality resulting from exposure to these environmental contaminants [...]. In a separate report from the New York Times, author Nina Agrawal highlights some of the caveats with the data. First of all, the study relies heavily on statistical modeling and assumptions, drawing from prior research that may include biases and confounding factors like diet or socioeconomic status. It also uses U.S.-based risk estimates that may not generalize globally and focuses only on one type of phthalate (DEHP). Additionally, as Agrawal points out, this is an observational study, showing correlation rather than causation. As such, more direct, long-term research is needed to clarify the true health impact of phthalate exposure.
