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 effec- tive, 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 Asia 1 , adopting multi-country strat- egies to better balance cost, risk, and operational efficiency. Additionally, the Global Electronics Association 2 reports that 59% of companies plan to increase their sustainability efforts in 2025, with printed circuit board and contract manufacturers leading the charge 3 . These shifts, while strategically necessary, intro- ▼ F i g u re 1 : E l e ct ro n i c s c o m p a n i e s a re i n c re a s i n g t h e i r s u st a i n a b i l i t y ef fo r t s .
