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

Raspberry Pi Cuts Product Returns By 50% By Changing Up Its Pin Soldering
Published on May 01, 2025 at 02:30AM
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).

Slashdot: US Army Soldier Pleads Guilty To AT&T and Verizon Hacks

US Army Soldier Pleads Guilty To AT&T and Verizon Hacks Published on February 20, 2025 at 01:31AM Cameron John Wagenius pleaded guilty to hacking AT&T and Verizon and stealing a massive trove of phone records from the companies, according to court records filed on Wednesday. From a report: Wagenius, who was a U.S. Army soldier, pleaded guilty to two counts of "unlawful transfer of confidential phone records information" on an online forum and via an online communications platform. According to a document filed by Wagenius' lawyer, he faces a maximum fine of $250,000 and prison time of up to 10 years for each of the two counts. Wagenius was arrested and indicted last year. In January, U.S. prosecutors confirmed that the charges brought against Wagenius were linked to the indictment of Connor Moucka and John Binns, two alleged hackers whom the U.S. government accused of several data breaches against cloud computing services company Snowflake, which were among the ...

Slashdot: AT&T Now Lets Customers Lock Down Account To Prevent SIM Swapping Attacks

AT&T Now Lets Customers Lock Down Account To Prevent SIM Swapping Attacks Published on July 02, 2025 at 01:30AM AT&T has launched a new Account Lock feature designed to protect customers from SIM swapping attacks. The security tool, available through the myAT&T app, prevents unauthorized changes to customer accounts including phone number transfers, SIM card changes, billing information updates, device upgrades, and modifications to authorized users. SIM swapping attacks occur when criminals obtain a victim's phone number through social engineering techniques, then intercept messages and calls to access two-factor authentication codes for sensitive accounts. The attacks have become increasingly common in recent years. AT&T began gradually rolling out Account Lock earlier this year, joining T-Mobile, Verizon, and Google Fi, which already offer similar fraud prevention features. Read more of this story at Slashdot.

Slashdot: Protecting 'Funko' Brand, AI-Powered 'BrandShield' Knocks Itch.io Offline After Questionable Registrar Communications

Protecting 'Funko' Brand, AI-Powered 'BrandShield' Knocks Itch.io Offline After Questionable Registrar Communications Published on December 16, 2024 at 01:04AM Launched in 2013, itch.io lets users host and sell indie video games online — now offering more than 200,000 — as well as other digital content like music and comics. But then someone uploaded a page based on a major videogame title, according to Game Rant. And somehow this provoked a series of overreactions and missteps that eventually knocked all of itch.io offline for several hours... The page was about the first release from game developer 10:10 — their game Funko Fusion, which features characters in the style of Funko's long-running pop-culture bobbleheads. As a major brand, Funko monitors the web with a "brand protection" partner (named BrandShield). Interestingly, BrandShield's SaaS product "leverages AI-driven online brand protection," according to their site, to "detect...
