OKI Launches Rigid-Flex PCBs with Copper for Space Use

OKI Circuit Technology, the OKI Group’s printed circuit board (PCB) business company, has developed rigid-flex PCBs with embedded copper coins that offer improved heat dissipation for use in rockets and satellite-mounted equipment operating in vacuum environments. Sales will start in August 2025. Targeting the rapidly growing New Space market, the new PCBs not only resolve the issue of heat management for high heat-generating components, but also enable space savings and weight reductions and reduce mounting man-hours because they are connector-less. OTC is targeting annual sales of 20 million yen in FY2026. Rigid-flex PCBs have a structure that combines a thin, light, soft, and durable flexible circuit board (FPC, Note 1) made from insulating film, with a high-strength rigid PCB. This structure allows bending for installation in tight spaces inside equipment.…
