Direct Metallization: A Sustainable Shift in PCB Fabrication
July 31, 2025 | Jim Watkowski, Harry Yang, and Mark Edwards, MacDermid Alpha Electronics SolutionsEstimated reading time: 1 minute
The global electronics industry is undergoing a significant transformation, driven by the need for more resilient supply chains and environmentally sustainable manufacturing practices. Printed circuit boards, the backbone of interconnection for electronic devices, are at the center of this shift.
Traditionally, PCB fabrication has relied heavily on electroless copper, a process that, while effective, is resource-intensive and environmentally hazardous. In response, many manufacturers are turning to direct metallization technologies as a cleaner, more efficient alternative.
Supply Chain Pressures and the Need for Diversification
According to Evergreen Analytics, tech giants are actively transitioning their supply chains to new locations across Asia1, adopting multi-country strategies to better balance cost, risk, and operational efficiency. Additionally, the Global Electronics Association2 reports that 59% of companies plan to increase their sustainability efforts in 2025, with printed circuit board and contract manufacturers leading the charge3.
These shifts, while strategically necessary, introduce significant challenges, particularly in terms of cost, lead time, and accurately measuring environmental impact. One of the most pressing concerns for supply chain managers is how to relocate production without compromising efficiency or sustainability. For instance, the traditional electroless copper process, reliant on multiple chemical baths and high water and energy consumption, is increasingly at odds with the industry's push toward more sustainable and efficient manufacturing practices4.
