On June24, 2025, Shenzhen - The global electronics manufacturing industry isundergoing a profound transformation led by PCBA (Printed Circuit BoardAssembly) technology innovation. With the commercialization breakthrough of 3Dprinting electronic technology, the emergence of a new generation of industrystandards through 2nm chip packaging, and the widespread adoption of AI fullprocess optimization systems, this traditional industry is undergoingunprecedented transformation and upgrading. According to the latest statisticaldata, the global PCBA market is expected to exceed $1.2 trillion by 2025, witha compound annual growth rate of 8.7%, becoming the core engine driving thedevelopment of the global electronic manufacturing industry.
1.3D printing electronic technology opens up a new era in the industry
Interms of technological breakthroughs, the Fraunhofer Institute in Germany hassuccessfully achieved direct 3D printing of 16 layer high-density interconnect(HDI) boards for disruptive manufacturing processes, compressing thetraditional 6-8 week production cycle to within 72 hours. This breakthroughtechnology not only supports complex 3D circuit structures, but also achievesline width accuracy of up to 50 μ m. For the industrialization of flexibleelectronics, China Pengding Holdings' latest stretchable PCBA solution has beencertified by manufacturers such as Xiaomi and OPPO and will soon be applied tothe next generation of foldable screen smartphones. This technology uses a newtype of conductive polymer material, which maintains over 95% conductivity evenafter 200000 bending tests.
Interms of market impact, according to IDC's prediction, by 2026, 3D printedelectronics will occupy 12% of the global PCBA market share, and thepenetration rate in high-end fields such as medical electronics and aerospacewill exceed 30%. And traditional PCB manufacturers such as Shennan Circuit andShanghai Electric Power Co., Ltd. are accelerating their transformation, withresearch and development investment increasing by 45% year-on-year in 2025.
2.AI reconstructs the entire PCBA industry chain.
Intelligentupgrade:

The system can optimize over 2000 productionparameters in real-time, increasing unit capacity by 40% and reducing energyconsumption by 25%.
GenerativeDesign Revolution: DeepPCB's AI design platform integrates over 10 million setsof circuit design solution databases, supporting engineers to quickly generateoptimized solutions through natural language input. Tests have shown that itsdesign efficiency is 50 times higher than traditional methods.
Evolutionof Industry Standards:
Thelatest AI-610 standard released by IPC includes artificial intelligence qualityinspection as an industry standard for the first time, requiring AI detectioncoverage of critical processes to be no less than 90%.
3.The 2nm era has spurred a revolution in packaging technology
Technologicalfrontiers:
The newparadigm of "chip as system": The Embedded Substrate technologylaunched by Sunlight integrates traditional PCBA functions directly into thechip package, reducing module size by 70% and improving performance by threetimes. This solution has been adopted by manufacturers such as NVIDIA and AMD.
Breakthroughin Ultra Precision Manufacturing: The nano level mounting system developed byChangdian Technology adopts quantum positioning technology to achieve amounting accuracy of ± 0.5 μ m, providing reliable support for 2nm chips.
Changesin market landscape:
TSMC,Samsung and other wafer fabs are extending into the PCBA field through advancedpackaging technology, and the industry boundaries are becoming increasinglyblurred.
TraditionalEMS manufacturers are accelerating deep cooperation with chip design companiesto form a new industrial ecosystem.
4.Green manufacturing enters the 2.0 era
Policydriven:
TheEU's Electronic Recycling Act requires the proportion of recycled materials inPCBA products to reach 40% by 2027 and increase to 65% by 2030.
Underthe promotion of China's "dual carbon" goals, the carbon emissionsper unit output of top enterprises have decreased by 58% compared to 2020.
technologicalinnovation:
Applicationof biobased materials: The mycelium substrate material developed by ShengyiTechnology is not only completely degradable, but its dielectric properties arealso 15% better than traditional FR-4 materials.
Zerowaste factory: Huawei Dongguan production base achieves precise control ofmaterial flow through digital twin technology, with a waste recycling rate of98.7%.
5.Geopolitics reshapes the supply chain map
Globallayout adjustment:
Deepeningthe "China+N" strategy: In Apple's supply chain, the proportion ofPCBA production capacity in Vietnam and India will increase from 35% in 2022 to68% in 2025. The recent acquisition of the Heshuo India factory by India's TataGroup marks an acceleration in the localization process.
Highend manufacturing return: Tesla has relocated the PCBA production of FSDautonomous driving modules from Shanghai to Austin, reflecting supply chainsecurity considerations in critical technology areas.
Regionalcharacteristics are manifested:
NorthAmerica forms an automotive electronic PCBA cluster centered around Mexico
SoutheastAsia focuses on consumer electronics manufacturing.
Chinaaccelerates the upgrade of PCBA to high-end equipment, military electronics andother fields.
