一．Tariff barriers: the "fault zone" of the global PCBA chain
1.Stratified dissection of policy lethality
The U.S. PCB tariffs onChina form a three-tier gradient: single-sided and multi-layer boards face alethal tax rate of 55%, the basic double-sided board tax rate is 30%, and a fewcategories such as server/data center PCBs enjoy exemptions. This differentiationdirectly fragmented the supply chain - a flexible board factory in Shenzhen wasforced to shut down two production lines due to a 55% tariff that caused USorders to plummet by 60%; Enterprises such as Shanghai Electric Co., Ltd.urgently shifted their consumer electronics production capacity to the tax-freeAI server board track.
2.Cost conduction butterfly effect
The shock wave oftariffs has spread to the whole industry chain: the tariff on imported high-endcopper clad laminates has increased by 25%, forcing the price of ShengyiTechnology's ABF film to increase by 18%; The cost of smart home PCBA in theUnited States rose by 12%, resulting in Amazon removing 7 low-margin products;The surge in the cost of building a factory in Southeast Asia has causedKingford Thailand to delay the start of production for 6 months.
二. Breaking tactics: the three engines from "detour" to"reconstruction".
1.Southeast Asia's production capacity springboard - the cracking code of thetariff firewall
Vietnam and Thailandhave become key transit hubs. Taiwan-funded companies such as XinxingElectronics and Zhending Technology will keep the front-end process ofmulti-layer boards in Chinese mainland, and transfer the back-end assembly toVietnam, taking advantage of the 10% tariff difference to break through.According to the data, Vietnam's PCB exports will exceed US$8.5 billion in 2025(an annual increase of 40%), of which 72% will be re-exported to North America.Another "semi-finished product breakthrough" model also worked:Victory Giant Technology shipped the semi-finished products of the 4-layerboard to the Mexican Free Trade Zone to complete the final welding, avoidingthe "Chinese origin" determination.
2.Technical Exemption Card Battle - Compete for the ticket to the duty-free track
Server PCBs become thegolden track. With a 99.2% AI-accelerated pallet yield, Shennan Circuit won a$200 million waiver order from NVIDIA. Material substitution is anotherbreakthrough path: Shengyi Technology's Low-DK high-frequency substrate haspassed Cisco certification, reducing tariff costs by 35% after replacing Rogersproducts in the United States.
3.AIIntelligent Manufacturing and Cost Reduction - "Digital Vaccine" forHedging Tariffs
AI-driven zero-defectmanufacturing is rewriting the cost equation. The missed detection rate oftraditional manual sampling is more than 8%, and the average monthly reworkcost is as high as 120,000 US dollars; The AI visual inspection increases thedefect recognition rate to 99.97%, and the monthly rework cost is reduced toless than 30,000 US dollars. After the introduction of the system at Foxconn'sZhengzhou plant, the gross profit margin of North American orders increased by5.3% against the trend. At the same time, digital scheduling is being promoted:Siemens' Teamcenter system has achieved global production capacity linkage, andthe response time for urgent orders at the Vietnam plant has been reduced to 72hours.
三. The battlefield of the future: the dual game of carbon tariffs andtechnological sovereignty
1.The "second strangulation" of the EU CBAM
From 2026, PCBA exportsto the EU will be subject to a carbon tax of $45 per ton. Hon Hai Group hasinvested US$2 billion to build a photovoltaic industrial park in Vietnam, withthe goal of covering 80% of its green power needs.
2.The ultimate battle of material localization
At present, high-endmaterials are still "stuck": 92% of high-frequency PTFE substratesare monopolized by American and Japanese companies, and 98% of IC substrate ABFmembranes rely on Japanese Ajinomoto. The hope to break the situation comes fromlocal innovation - Xuzhou Bokang, a photoresist company invested by HuaweiHubble, has achieved mass production, and the Chinese Academy of Sciences hasdeveloped a silicon-based PCB technology with a temperature resistance of200°C.
四. Conclusion: The Rules of Survival in the New Era of Globalization
"When the 55%tariff wall stands, the real winner is not crying under the wall, but crossingit with the springboard of Southeast Asia, splitting it with the blade of AI,and finally rebuilding the rules on the battlefield of carbon tariffs." Short-termsurvival depends on the core formula: 10% tariff differential in Southeast Asia+ server PCB exemption > 55% blockade line. Long-term competitivenessdepends on three pillars: material autonomy (domestic substitution breaksthrough technology blockade), zero-carbon manufacturing (green power transitionto cope with carbon tariffs), and smart factories (AI reduces costs andincreases efficiency throughout the process).
