As an Electronics Manufacturing Services (EMS) provider, we specialize in precision manufacturing of printed circuit board and system level assemblies. Since 1989, we’ve been known as a quality leader in high-mix, high-complexity projects. Today, we’re continually finding new ways to drive down costs while maintaining our high level of flexibility and responsiveness.

By incorporating advanced Tier One technologies and systems, it allows us to manufacture various designs with various complexities, from simple commercial PCBAs to more complex higher dense circuits with BGAs, Flip Chip, and Chip On-Board (COB) technologies. Whether you need assembly services for a new design, or higher volume manufacturing with fully managed documentation and material purchasing, we have what it takes to help you succeed.
