About Magvention
Magvention, founded in 2008, is a world innovative leader in micro-magnetic relays. Its main business is in research, development, production, and sales of a new generation of micro-magnetic relay products and high performance RF coaxial switches. Its technical expertise includes relays, microelectronics, MEMS, electronic ceramic materials and processes. Its products lead in size, power consumption, and reliability. The company imported an advanced set of LTCC equipment (casting, cutting, punching, printing, drying, laminating, hydrostatic pressure, sintering, etc.), and can provide LTCC OEM services. It is headquartered in Suzhou (SIP), China.
