HCM.SYSTREL (SERMA Group) produces high reliability components such as SCM, MCM & custom hermetic packages, according to MIL and Aerospace specifications.

With over 30 years of experience and a certified quality system, we provide global back-end services (wafer sawing, dice visual inspection, assembly and test) for a wide range of devices, from bare dies and wafer to qualified components, for obsolete, reengineered or customized ASIC components.

Merging our microelectronics know-how with a last generation of surface mounted technology (SMT) line, we also address high density hybrid technologies.
