Industry Outlook: Why AI PCBs Cost More—Opportunities for Taiwan’s Supply Chain and New Engineering and Sourcing Challenges

Why can a change in materials or stackup significantly affect a PCB quotation? As AI servers and high-speed switches evolve, engineering and purchasing teams in Taiwan face cost changes shaped by electrical performance, manufacturing requirements, and supply arrangements. Understanding these differences is more useful to product development teams than following record board prices. What matters to a project is whether the design passes validation and can subsequently be delivered consistently within an acceptable budget and schedule.

Essential Knowledge for R&D: Understanding Dielectric Constant—from Material Polarization to High-Speed PCB Design

Two traces with identical geometry may exhibit different characteristic impedance, propagation delay, and resonant behavior when the PCB laminate is changed. The difference often comes not from the copper itself, but from the dielectric surrounding it. This material property is relative permittivity, commonly called dielectric constant or Dk in the PCB industry. Dk, however, is not a permanent identification number for a material. It can vary with frequency, temperature, moisture content, material orientation, and test method. The practical objective is therefore not to memorize the Dk of FR-4, water, or ceramic materials. Engineers need to understand where the value comes from and which value is appropriate for a particular design.

Design Practice: An Edge AI Camera Is More Than a Camera with an AI Chip—Seven PCB Design Priorities

A conventional USB or IP camera primarily captures images and transfers them to a host or server. An Edge AI camera must also perform image preprocessing, AI inference, event decisions, and communications locally. Once computation moves into the camera, PCB design involves much more than integrating an image sensor and a network interface. A single Edge AI camera board may combine a CMOS image sensor, SoC or NPU, DDR memory, storage, Ethernet, PoE power, USB, wireless connectivity, audio, and motor control. When these functions are compressed into a small enclosure, signal integrity, power integrity, thermal management, EMI, and manufacturing risk become closely interconnected.

Essential Knowledge for R&D: Which PCBs Do Electric Vehicles Need? A Selection Guide from BMS to ADAS

An electric vehicle combines a high-voltage power system operating at hundreds of volts, currents ranging from tens to hundreds of amperes, low-noise sensing, high-speed in-vehicle communications, and millimeter-wave radar. Although all these circuits operate in the same vehicle, they place very different demands on their PCBs. There is therefore no single answer to the question, “Which PCB should an EV use?” A battery-management system requires accurate measurement and high-voltage isolation. A traction inverter emphasizes high-current switching and thermal management. ADAS electronics require signal integrity and high-density interconnects. The correct approach is to understand each subsystem’s electrical, thermal, and mechanical loads before selecting the laminate, copper weight, stackup, and manufacturing process.

DFM in Practice: PCB Silkscreen Is More Than Reference Designators—Eight Checks Before Fabrication

PCB silkscreen, also called the legend or overlay layer in EDA software, is one of the most underestimated parts of a printed circuit board. It carries no current, yet it directly affects SMT assembly, manual inspection, functional testing, troubleshooting, repair, and product traceability. A reference designator that looks complete in the PCB editor may be reduced to half a character after CAM processing. A polarity mark may also become useless if the installed component covers it. On a high-density PCB, effective silkscreen design is not about fitting every possible label onto the board. It is about preserving useful information that can be manufactured consistently.
