RD Essentials: RF PCB Design Is No Longer Black Magic — 6 Modern Strategies for the 5G–mmWave Era

For the past 20 years, RF PCB design has been treated as "black magic" — a domain only a handful of specialists could touch, and failures were typically fixed by respinning the board multiple times. That has changed completely. 5G FR2, Wi-Fi 7, 77 GHz automotive radar, satellite communications, optical interconnect on AI servers — RF has moved from "specialty requirement on niche programs" to "something almost every hardware engineer will face." For Taiwan R&D teams, the real challenge is no longer whether to engage with RF, but how to use systems thinking, simulation tools, EDA integration, and early DFM alignment to move from "three board spins before convergence" to "one-shot convergence with stable ramp." This article dissects six strategic shifts in modern RF PCB design.

RD Essentials: How to Design a Multilayer PCB Stack-up — 6 Key Decisions from Copper Foil to HDI

In an era shaped by AI servers, automotive radar, Wi-Fi 7, and silicon photonics, multilayer PCB stack-up is no longer just a manufacturing spec. When trace rates cross 112G PAM4, BGA pitches shrink to 0.4 mm, and target impedance must be held to ±10%, stack-up transitions from a fab-side "internal spec sheet" into a design decision the layout engineer must own from day one — it simultaneously determines signal integrity, EMI behavior, board thickness, yield, and cost. This article starts from the basic definition of a stack-up and walks through to the HDI sequential-lamination nomenclature, unpacking the six decisions Taiwan R&D teams most commonly underestimate when planning multilayer boards.

RD Essentials: How to Choose PCBs for Electric Vehicles — 5 Material Categories and 6 Design Challenges from BMS to 800V Fast Charging

Driven by AI compute, autonomous driving, and 800V fast-charging architectures, the electronic platform of an EV is evolving from "traditional vehicle + a few electrification modules" into an integrated system built around high-voltage power electronics and high-speed communications. For Taiwan R&D engineers, this creates a very concrete pain point: inside a single EV, the BMS, traction inverter, OBC, ADAS, and infotainment subsystems all have completely different PCB requirements. Apply one FR-4 stackup to everything, and you'll either burn through thermally or lose to EMI. This article dissects EV PCB selection through three dimensions: laminate materials, stackup architectures, and automotive-grade standards.

Industry Watch: HVLP Copper Foil Generational Shift — Why HVLP4 Share Jumped 2.5× in a Single Year

While the market focuses on when NVIDIA's Vera Rubin platform and CSP in-house ASICs will ramp, a generational shift in one of their key materials is quietly accelerating. According to data from ITRI's Industrial Technology Research Institute citing Fuji Chimera Research, the combined shipment share of HVLP3/4 high-end copper foil is projected to jump from 27.9% in 2025 to 45.6% in 2026. HVLP4 alone climbs from 9.3% to 23.0% — nearly a 2.5× increase in a single year. This transition, driven by AI servers and 800G/1.6T high-speed networking, is reshaping the material supply chain across CCL, PCB fabricators, and end brands.

DFM in Practice: 5 Major PCB Design Challenges — Engineering Solutions Across Signal, Power, Thermal, and Structural Reliability

As AI, IoT, and high-density interconnect applications advance in parallel, PCB engineers are forced to balance three competing axes — electrical, mechanical, and thermal — at the same time. Signals must run faster, power must be cleaner, boards must be thinner, and reliability must improve another notch. Many Taiwan R&D teams have hit the same trap: simulations pass, the prototype works, but mass production fails on signal integrity, PDN noise, or thermal stress. This article unpacks the five most common PCB design challenges from a manufacturing-side DFM perspective, along with the engineering countermeasures for each.

Engineering Essentials: 7 Principles for PCB EMI/EMC Design — Why Stackup and Return Path Decide the Outcome

As AI servers, automotive electronics, 5G/Wi-Fi 7, and edge AI become ubiquitous, EMI/EMC has shifted from a "compliance hurdle" to a determining factor for whether a product can ship in volume. A board that runs cleanly on the bench can show up at the EMC lab with a +15 dB spike at 200 MHz — and the first instinct is usually to add a shield can or absorber sheet. But the root cause is almost always buried in the stackup and routing decisions made weeks earlier. This article walks through 7 PCB EMI/EMC design principles and explains why stackup and return paths — not shielding — are what actually decide compliance.
