Overview
H.I. Systec is headquartered in Koshi, Kumamoto. It designs and makes burn-in boards and the racks that hold them, test heads and test fixtures for power devices.
It also assembles printed circuit boards and makes industrial wire harnesses, so most of the work for its test hardware is done in house.
Business: Burn-in boards, racks and test fixtures
Why it matters
- Burn-in boards hold many devices in an oven under voltage to screen out early failures, and each board is designed for a specific package.
- Koshi is in the Kumamoto semiconductor cluster around JASM and Sony's image sensor fabs.
