The facilities lotus sensor company’ headquarters are carefully thought out to provide world class, cutting-edge technology.


What is a cleanroom?

A cleanroom is an enclosed facility that shuts out the outer air, and the purity of the air inside is secured. Also, the ingredients, the equipment, and the people coming in are under strict supervision so they do not bring dust (waste and impurities) into the room.
Cleanrooms are necessary for sensor and semiconductor manufacturing.
