While perfecting our supply chain, we have established a professional quality inspection team. The products delivered to customers need to pass our senior IC quality inspectors and quality control team's inspection and quality control to ensure that the quality of the products is within the range of safety standards. As IC products have extremely high requirements for parameters and precision, product quality control is an indispensable link. In the face of a complex market environment, we have high requirements and must be professional, and are confident in providing product assurance for our customers.
