At Coresix, cleanliness is treated as an independent technology, procedures for which are continuously monitored and improved upon. With many of today’s technologies, the introduction of foreign matter to the process can have serious impact on production yields and product performance. Coresix provides a unique niche in our ability to clean glass and maintain the highest level of cleanliness to the customer’s door.

Cleanrooms are classified according to the number and size of particles permitted per volume of air. Large numbers like "class 100" or "class 1000" refer to FED-STD-209E, and denote the number of particles of size 0.5 µm or larger permitted per cubic foot of air.

A class 100 cleanroom maintains less than one hundred particles larger than 0.5 microns in each cubic foot of air space.
