DALLAS – Principal Mineral has acquired PCB materials manufacturer Isola Group and secured approximately $280 million in new funding to support expansion, technology development and supply-chain investments.

The acquisition adds Isola's copper-clad laminate and dielectric prepreg portfolio to Principal Mineral's existing operations, which include Camden Copper, a producer of electrodeposited copper foil. Together, the businesses supply two key materials used in printed circuit board manufacturing, strengthening the company's position in advanced electronics supply chains.

Principal Mineral said the funding will support integration of the combined company, expansion of manufacturing capacity and investments across North America, Europe and Asia. Following the transaction, the company will employ approximately 1,300 people across 10 facilities worldwide.

The company said the combination is intended to improve supply-chain resilience for industries including aerospace, communications, satellite systems, AI infrastructure and energy.
