When a PCB Carries 1,000 Amps: The Thermodynamics, Materials Science, and Manufacturing Limits You Must FaceBased on AnyPCBA's small-to-medium volume PCB and PCBA manufacturing experience, this guide explains the thermodynamics, materials science, and manufacturing limits of high-current PCBs—from heavy copper and thermal vias to IPC-2152 trace width and etching undercut—and how DFM review prevents catastrophic failure before production.5 min read·anypcba.hashnode.dev1d ago
When AI Chips Overheat: How PCBs Are Evolving from Insulators to Heat SinksAs AI GPUs push past 1,000W per chip, traditional FR-4 PCBs can no longer handle the heat. This article explores how PCBs are evolving from simple insulating substrates into core thermal conduits—covering thermal via arrays, metal core PCBs (MCPCB), and embedded copper coins—and the manufacturing challenges that come with them.5 min read·anypcba.hashnode.dev5d ago
When Capacitors "Disappear" from the PCB Surface: The Physics and Manufacturing Limits of Embedded PassivesAs electronic devices shrink and chip pin pitches tighten, PCB surface space is completely exhausted. Embedded passive technology—integrating capacitors and resistors directly into the PCB stack-up—offers a revolutionary solution. This article explores the physics behind embedded passives, how they dramatically improve power and signal integrity, and the extreme manufacturing challenges they present.6 min read·anypcba.hashnode.devNov 3
When Code Meets the PCB: From "Deadlocks" to Physical DebuggingSoftware engineers are used to debugging logical errors with logs and profilers. But when code runs on a physical PCB, "latency," "packet loss," and "deadlocks" take on a whole new meaning—impedance mismatch, ground bounce, and parasitic parameters. This article maps familiar software concepts to their physical counterparts and explains how to debug the "silent" bugs of the hardware world.4 min read·anypcba.hashnode.devOct 30
When Hardware Hits "Dependency Hell": Why a BOM Is Not a package.jsonSoftware developers are used to fixing dependency issues with a quick npm audit fix. But in hardware, dependency hell is physical. When a core chip goes End-of-Life or lead times jump to 52 weeks, you can't "fork" silicon. This article explores why BOM management is fundamentally different from software dependency management, and how to build resilience into your hardware supply chain.4 min read·anypcba.hashnode.devOct 27
