The printed circuit board (PCB) industry has faced unprecedented supply chain turbulence over the past five years. From the COVID-19 pandemic’s factory shutdowns and surging demand for electronics to geopolitical tensions around Taiwan and ongoing material shortages, procurement professionals have navigated delays, price volatility, and allocation struggles that threatened production timelines and profitability. As we reflect on these disruptions in late 2025, the lessons learned are clear: reactive strategies are no longer sufficient. Building resilience through diversification, proactive planning, and strategic partnerships is essential for sustainable PCB procurement.
Understanding what a PCB is—at its core, a foundational platform connecting electronic components—highlights why disruptions ripple across industries like automotive, consumer electronics, medical devices, and telecommunications. A single bottleneck in copper clad laminate (CCL), resins, or semiconductors can halt assembly lines worldwide. This article examines key disruptions from 2020 onward, their impacts on PCB procurement, and practical strategies to overcome them moving forward.
The COVID-19 Pandemic: The Catalyst for Global Shortages (2020–2023)
The semiconductor shortage that began in late 2020 exposed the fragility of just-in-time manufacturing models. Factory closures in Asia, combined with a sudden spike in demand for home office equipment, gaming consoles, and remote learning devices, created a perfect storm. Automotive manufacturers, who had canceled orders early in the pandemic, found themselves at the back of the queue when demand rebounded, leading to production cuts of millions of vehicles.
For PCB procurement, the ripple effects were profound. Lead times for critical components stretched from weeks to over a year, while prices for passive components and ICs surged. Copper foil and laminate shortages compounded issues, as PCB fabricators struggled to secure materials. By mid-2021, many EMS providers reported allocation challenges, where suppliers prioritized high-volume customers, leaving smaller buyers scrambling.
The pandemic also highlighted logistical vulnerabilities: port congestions, container shortages, and air freight disruptions delayed shipments. One notable example was the Suez Canal blockage in 2021, which exacerbated existing delays. As a result, PCB lead times ballooned from 4–6 weeks pre-pandemic to 20–30 weeks at peak.
Lessons from this period underscore the dangers of single-source dependency. Many companies learned the hard way that over-reliance on Asian suppliers—particularly in China and Taiwan, which dominate CCL and advanced PCB production—left them exposed.
Geopolitical Tensions: Taiwan’s Role and Ongoing Risks
Taiwan’s dominance in advanced semiconductors and high-end PCBs adds a layer of geopolitical risk. Producing over 60% of the world’s semiconductors and a significant share of HDI and multilayer boards, Taiwan is central to global supply chains. Escalating U.S.-China tensions, including export controls on advanced chip technology and military exercises around the Taiwan Strait, have heightened concerns about potential blockades or conflicts.
Analysts estimate that a full disruption could cost the global economy trillions annually, with PCB-dependent sectors like AI hardware, 5G infrastructure, and electric vehicles hit hardest. Even short-term quarantines or trade restrictions could trigger material shortages, as seen with China’s 2023–2025 export limits on gallium and germanium—key for high-frequency PCBs.
Red Sea shipping disruptions in 2024–2025 and U.S. tariffs on Chinese imports further complicated procurement, driving up costs and prompting onshoring trends. Southeast Asia (Vietnam, Thailand) saw PCB output growth of 20–30%, as companies diversified away from concentrated risks.

Material and Component Shortages in 2024–2025
Entering 2025, recovery from pandemic backlogs was uneven. While basic FR-4 boards stabilized, high-end materials faced new pressures from AI and EV demand. CCL production, heavily concentrated in China (58%) and Taiwan (22%), suffered from typhoons, energy shortages, and capacity constraints, pushing lead times to 20+ weeks.
Rare earths, copper, and specialty resins remained volatile due to mining disruptions and export controls. Workforce shortages in fabs and rising sustainability regulations added compliance burdens, increasing costs for halogen-free and recyclable materials.
These challenges manifested in higher rejection rates, quality issues from unvetted suppliers, and inflated prices—sometimes 50–100% above pre-2020 levels for critical items.
Strategies for Building Supply Chain Resilience
The disruptions of recent years have spurred a shift toward proactive resilience. Here are key strategies that leading companies are implementing:
1. Supplier Diversification and Regional Sourcing
Moving away from single-source models is paramount. Companies are qualifying multiple suppliers across regions: Southeast Asia for cost-effective alternatives, the U.S. and Europe for high-reliability needs, and nearshoring for faster response.
Onshoring PCB assembly has gained traction in 2025, driven by tariffs and lead-time reductions. U.S.-based facilities offer ITAR compliance and shorter shipping, offsetting higher labor costs with stability.
2. Inventory Buffering and Strategic Stockpiling
Maintaining 45–90 days of inventory for critical components has become standard. AI-driven forecasting tools help optimize stock without tying up excessive capital, focusing on long-lead-time items like HDI substrates.
3. Design for Flexibility and Manufacturability
Engineers are incorporating multi-footprint designs, allowing alternate components. Early DFM (Design for Manufacturability) reviews with fabricators identify risks, suggesting drop-in replacements or material swaps.
4. Enhanced Visibility and Digital Tools
Real-time supply chain platforms provide transparency, tracking disruptions from raw materials to assembly. Partnerships with EMS providers offering global sourcing networks ensure priority access during allocations.
5. Long-Term Partnerships and Contingency Planning
Building strong relationships with reliable suppliers yields better communication on lead times and allocations. Comprehensive contingency plans—including alternative BOMs and backup fabs—enable quick pivots.
6. Sustainability and Compliance Integration
Aligning with RoHS, REACH, and conflict minerals requirements future-proofs procurement, as regulations tighten.
Case Studies: Success in the Face of Adversity
Automotive OEMs that diversified early recovered faster post-2021, qualifying Southeast Asian board shops and stockpiling substrates.
Consumer electronics firms using turnkey providers with diversified sourcing avoided major delays in 2024 AI hardware launches.
A medical device company mitigated 2025 resin shortages by redesigning for bio-based alternatives, partnering with innovative fabricators.
Looking Ahead: A More Resilient Future
As of December 2025, the PCB supply chain shows signs of stabilization, with new capacity coming online in diversified regions. However, geopolitical risks and demand from AI/EV sectors persist. The industry is projected to grow steadily, but only resilient players will thrive.
Procurement teams must view supply chain management as strategic, investing in data-driven tools and partnerships. Choosing a reliable partner knowledgeable in global sourcing, instant quoting, and turnkey solutions can make all the difference.
In an era of uncertainty, understanding the fundamentals—like what constitutes a robust pcb board design resilient to disruptions—is key. By applying lessons from recent crises, companies can turn challenges into competitive advantages, ensuring uninterrupted innovation in electronics.
The path forward demands vigilance, adaptability, and collaboration. Those who embrace these principles will not only overcome current hurdles but position themselves for sustained success in the dynamic PCB landscape.
