AXT Inc of Fremont, CA, USA — which makes gallium arsenide (GaAs), indium phosphide (InP) and germanium (Ge) substrates and raw materials at plants in China — intends to offer and sell shares of common stock in a public offering. In connection with the offering, the firm also expects to grant the underwriters a 30-day overallotment option to purchase up to an additional 15% of the shares offered in the public offering price, minus the underwriting discounts...

InPHRED Inc of Boston, MA, USA (a developer of next-generation photonics solutions for consumer sensing and digital health that was founded in 2023 at Yale University) has announced its formal expansion into the data-center optical interconnect market, extending its nanoporous platform into high-speed connectivity solutions for next-generation AI infrastructure...

I made this little piano using an ATtiny85 and a some push buttons. All 12 keys are read through a single ADC pin using a resistor-ladder voltage divider. Each button taps a different point in the chain, so the voltage tells the chip which key is down. Functional but quite limited as only one key really works at a time. This was my first project to learn the ATtiny85 and I'm happy with how it turned out. Sounds pretty rough though. submitted by /u/RAZK0M [link] [comments]

Applied Optoelectronics Inc (AOI) of Sugar Land, TX, USA (a designer and manufacturer of optical and hybrid fibre-coaxial networking products for AI data centers, cable TV and broadband fiber access networks) plans to expand its Houston-area footprint through the addition of two adjacent buildings in Pearland, Texas, adding about 388,000ft2 of manufacturing capacity...

Applied Optoelectronics Inc (AOI) of Sugar Land, TX, USA (a designer and manufacturer of optical and hybrid fibre-coaxial networking products for AI data centers, cable TV and broadband fiber access networks) received a new $71m order for 800G single-mode data-center transceivers in early April from one of its major hyperscale customers. This marks $124m in orders from this customer since mid-March, which will more than double the existing backlog from this customer...

Market analyst firm TrendForce forecasts that the global AI-focused optical transceiver market will rise at more than 57% year-on-year from US$16.5bn in 2025 to $26bn in 2026, as it has entered a phase of rapid growth. This surge is driven not only by specification upgrades but also reflects a broader structural reshaping of the optical communications supply chain amid accelerating AI data-center deployment...

The UK Semiconductor Centre (UKSC) has appointed Brian Robertson as director of international partnerships to lead on strengthening the UK’s global position in semiconductors and deepening connections between the UK ecosystem and international partners...

Tried to use it to light some LED’s though I think the circuit expects a battery voltage to use as feedback as it has very low output current otherwise. Short circuit current was 300mA submitted by /u/ram_the_socket [link] [comments]

Current setup 😅 ESP32 + RFID + SDR + random modules Not sure if this will fully work yet… But it’s getting interesting 👀 Any ideas what I should add next? submitted by /u/AppropriatePen283 [link] [comments]

There must be a T48 UV erasing addon with the EPROM blank check. 270-280nm 800mW diode. submitted by /u/nerovny [link] [comments]

I have been designing PCBs to carry a small microcontroller, an RS485 transceiver, an LED and the associated balance of plant required to make lights for my ROV. Space is at a premium, so track sizes are being chosen to minimise real estate used. KiCad has a netclasses setup page that uses IPC 2221 requirements and PCBway capabilities. I have come up with a sensible set of pre-defined values https://philipmcgaw.com/kicad-traces-net-classes/ submitted by /u/skippyuk [link] [comments]

Infineon Technologies AG of Munich, Germany says that radiation-hardened (rad-hard) devices from its IR HiRel (high-reliability) division supported the electronic backbone — from critical power supply and control systems to data communications — were at the heart of the Orion capsule of NASA’s Artemis II mission, which recently returned from its 10-days around the Moon (reaching the furthest distance from Earth ever achieved by crewed spaceflight)...

Nuvoton Technology of Kyoto, Japan has announced the start of mass production of the KLC434FL01WW high-power violet laser diode (402nm, 4.5W), which achieves what is claimed to be industry-leading optical output in a 9.0mm-diameter TO-9 CAN package, for continuous-wave (CW) operation at a case temperature (Tc) of 25°C. Due to the proprietary device structure and heat-dissipation design technology, the new product achieves 1.5 times the 3.0W optical output of the firm’s conventional 402nm product in a TO-9 CAN package (the KLC432FL01WW), contributing to improved production throughput in optical equipment such as maskless lithography systems. Furthermore, adding this product to the firm’s lineup enables the product portfolio to support major photosensitive materials used in advanced semiconductor packaging...

Automated test equipment (ATE) supplier Teradyne is bolstering its test solutions for semiconductor design by acquiring TestInsight, a provider of test program creation, pattern conversion, and pre-silicon validation tools used across ATE platforms and semiconductor design environments.

By acquiring a supplier of semiconductor test development, validation, and conversion software, Teradyne aims to scale its next generation of pre-silicon validation and automated pattern generation technologies. That strengthens Teradyne’s ability to support semiconductor design-in activities to accelerate time-to-market in the emerging AI and data center markets.

Greg Smith, president and CEO of Teradyne, calls TestInsight’s tools foundational to modern test program development. “By integrating the TestInsight team into Teradyne, we enhance our ability to help customers achieve silicon readiness faster and with greater confidence.”

The acquisition will allow Teradyne to combine its ATE platforms with TestInsight’s tightly integrated design-to-test workflow, thereby reducing debug cycles, improving coverage, and enabling earlier test program readiness. In short, the acquisition of a design-to-test software firm will help Teradyne close the gap between design and test in semiconductor design environments.

TestInsight announced that it will continue to support its existing customers across all ATE platforms.
