Quality Control

Each product is scrutinized with extensive quality control checks, from design analysis for manufacturing ability to design rule checks and comprehensive testing. Testing takes place during each stage of the design and manufacturing process. Testing procedures overload products to much higher levels than they are likely to face in real-world applications. All products are 100% functionally tested, including a burn-in test and a manufacturing test, such as the control of open, short, the weld quality, and a surface cleanliness test.
