Siemens Digital Industrial Software recently announced the completion of its acquisition of DownStream Technologies. DownStream is a leading supplier of manufacturing data preparation solutions in the field of printed circuit board (PCB) design. This acquisition will further strengthen Siemens' PCB design solutions and expand its market presence in small and medium-sized businesses (SMBs) in the electronics industry.

Mike Ellow, CEO of Siemens EDA, said, "This acquisition is an important step for Siemens EDA in the mid size PCB market, which can help DownStream's customers accelerate product time to market, improve product quality, and optimize cost-effectiveness. Integrating DownStream Technologies' technology into Siemens EDA's product line will help both parties create comprehensive and advanced manufacturing data preparation solutions, enabling customers to achieve a smooth transition from design to production in a digital and scalable electronic system design process. ”

DownStream Technologies was founded in 2002 and is headquartered in Marlborough, Massachusetts. It is a leading supplier of manufacturing data analysis, processing, and PCB design documentation solutions. Its widely adopted CAM350 toolkit enables visualization and validation of PCB design data, and automatically prepares for the manufacturing process.

DownStream's patented tool BluePrint PCB is an industry-leading document preparation solution that can automatically create highly detailed manufacturing documents for customers of all sizes. By reducing errors and simplifying the transition process from design to production, BluePrint PCB can effectively improve the overall development efficiency of PCBs. The integration of BluePrint PCB and Siemens PCB design solutions can provide customers with seamless workflows, enhancing digital continuity and manufacturing readiness.

Rick Almeida, founder of DownStream Technologies, said, "We are delighted to join forces with Siemens to integrate decades of expertise from DownStream into Siemens' extensive ecosystem. We will work together to create a comprehensive integrated solution that combines breadth and depth, helping PCB designers to deliver design to manufacturing more efficiently and confidently.

The transaction was completed on April 7, 2025, and the terms of the transaction were not disclosed.
