What the 3+N+3 Notation Actually Means The notation describes a build-up construction. The number before the plus sign is the count of laser-drilled build-up layers on one side, the middle value is the number of conventional core layers, and the number after the plus sign is the build-up count on…

One Chip Where Two Used to Sit In August 2026 a domestic vehicle model entered the market carrying a cockpit and driving integration platform that places intelligent cabin functions and assisted driving tasks on a single system-on-chip in a native architecture. The processor uses a four nanometre process with a…

From Demonstration Flights to Order Books In July 2026, an electric vertical take-off and landing aircraft developer signed orders for 230 aircraft on the opening day of a low-altitude economy exhibition, bringing its total order book to 860 units from fourteen customers. Both a passenger model and a cargo variant…

Smart Hardware Development: From Concept to a Manufacturable Product A smart hardware product is a system, not a circuit board. The enclosure decides the antenna performance, the firmware decides the battery life, the certification body decides the schedule, and the component choices decide whether the product can be built at…

Automotive PCB Design Outsourcing: What Automotive-Grade Really Means Automotive electronics is one of the few markets where a board is expected to work after ten years of heat, vibration and electrical abuse, and where a single field failure can trigger a recall. That expectation changes the design process itself, and…

Special Material PCB Fabrication: Aluminum, High-Frequency and Rigid-Flex FR4 covers most products, and most PCB fabrication quotations quietly assume it. The projects that do not fit the assumption are the ones where a supplier relationship is tested: LED lighting that needs a metal core to move heat, RF modules that…

How to Choose an SMT Assembly Factory: Equipment, Inspection and Support By the time a hardware project reaches the SMT stage, the design is finished and the components are on order, and the yield of every unit after that point depends on the factory. Cold joints, bridges, shifted parts and…

Choosing an Industrial Control PCB Design Partner: What Really Matters Industrial control hardware punishes optimism. A board that works on the bench has to keep working for a decade inside a cabinet that is hot, dirty and electrically noisy, and the cost of a failure is not the price of…

Why Material Choice Outweighs Layer Count A board with more than twenty layers is often described as a stacking problem, but the more common cause of failure is material selection. Dielectric constant, coefficient of thermal expansion, glass transition temperature and copper foil profile interact with each other, and each of…

Clearing Up What the Neural Band Actually Does Through September 2026, Meta continued expanding the AI and social features of its Ray-Ban Display glasses, including new assistant capabilities and tighter integration with its messaging and photo applications. The companion Neural Band that ships with the display product is widely described…
