Robot Joint FPC: Bend Life Beyond Consumer Electronics A robot joint FPC is asked to do something consumer flexible circuits are not. On 25 August 2026 a supplier obtained a patent covering a positioning structure for flexible circuits in augmented reality glasses, and in the same period another manufacturer described…

78-Layer PCB Backplanes: Where Manufacturing Meets Its Limit A 78-layer PCB backplane is the product that shows where board manufacturing currently stops. Industry information published on 23 August 2026 described the next generation of orthogonal accelerator architecture, in which compute tray boards rise from twenty six to thirty layers, the…

PTFE PCB: Why Material Choice Decides High-Speed Backplanes A PTFE PCB is what a backplane becomes when data rates outgrow ordinary laminate. Industry surveys in August 2026 described the material route for the next generation of orthogonal backplanes as still under validation, with polytetrafluoroethylene, M9 class low loss laminates and…

Energy Storage PCB: When Thick Copper Becomes Scarce An energy storage PCB has moved from a supporting component to a constrained resource. Reports in August 2026 described more than ten storage companies issuing price increase notices ranging from five to thirty percent, a rebound in lithium carbonate prices, rising costs…

Edge AI Phone PCB: Why On-Device Models Change the Board An edge AI phone PCB is being redesigned because the workload inside the phone has changed. Supply chain reporting in August 2026 described the next generation of mobile processors strengthening their neural processing capability, possibly with a new package arrangement,…

GPU Power Delivery PCB: From 300 Watts to 2300 Watts A GPU power delivery PCB has moved from a modest power distribution task to one of the hardest problems on a server board. Industry reporting in August 2026 described accelerator power rising from about three hundred watts in the Volta…

Embedded Chip PCB: Putting Power Devices Inside the Board An embedded chip PCB reverses the usual relationship between a component and its carrier. In a half year report published in August 2026, a Chinese board manufacturer described a technology that embeds power dies directly inside the printed circuit rather than…

Liquid Cooling Server PCB: What Changes at Rack Scale Liquid cooling has stopped being an accessory for a few hot components and become the infrastructure a rack is built around. Research published in August 2026 described the transition as the latest accelerator platform moved to full production, with a completely…

ABF Substrate Shortage: The Constraint Behind AI Chips The ABF substrate shortage has become the least visible constraint in the artificial intelligence supply chain. Industry surveys in August 2026 reported that demand for Ajinomoto build up film substrates tightened again as graphics processors, custom accelerators and co-packaged optics entered a…

SiC Power Module PCB: Where the Heat Actually Goes A SiC power module PCB cannot be designed in isolation from the substrate beneath it. Industry reporting in August 2026 described work to modify direct bonded copper substrates with hexagonal boron nitride, aiming at the thermal stress and interface reliability problems…
