Reliability Assurance

Provide excellent quality products to our customers by verifying quality reliability. This is done by utilizing test chambers which replicate various environmental factors such as temperature, humidity, vibrations and moisture conditions. Durability tests are then established with combinations of each environmental condition. In addition, a hemi-anechoic chamber is used for the reduction of abnormal sound and noise in the pursuit of comfort for customers.
