Chongqing Zhongshun Microelectronics has long been engaged in the R&D and mass production of semiconductor IC packaging, MEMS sensors and image camera modules. Taking standardized quality management as the core foundation of the enterprise, it has built a closed-loop quality control system covering the whole chain of R&D, production, testing and delivery. The company holds a number of internationally authoritative quality system certifications, special industrial qualifications and official scientific and technological innovation recognition certificates, which provide complete and authoritative endorsement for product quality.

- The company has obtained multiple internationally authoritative system qualifications including ISO9001 Quality Management System Certification and ISO14001 Environmental Management System Certification, meeting the access standards of customers in various fields such as consumer electronics, industrial equipment and automotive electronics. The factory is equipped with dust-free packaging workshops and an independent reliability testing laboratory furnished with a full set of precision testing equipment for high-low temperature shock, damp-heat durability, optical imaging, electrical performance, sealing performance and electrostatic protection. A four-level quality inspection process has been established, covering sampling inspection of incoming raw materials, in-process patrol inspection of semi-finished products, full-performance testing of finished products and re-testing of delivery reliability. Batch-by-batch compliance verification is conducted for QFN, DFN and BGA chips, optoelectronic, pressure and temperature MEMS sensors, as well as various image sensor modules, supported by complete third-party performance test reports and factory qualification certificates, enabling traceability of product quality for all batches.

- Meanwhile, the enterprise has been officially recognized as a National High-tech Enterprise, Provincial Specialized, Refined, Distinctive and Innovative SME, and Technology-based SME. It possesses dozens of invention patents and utility model patents related to chip packaging and sensor structures, consolidating the foundation of quality control from the perspective of process technology. All product lines strictly comply with RoHS and REACH hazardous substance control standards to meet domestic and foreign electronic environmental access requirements and pass compliance audits for export projects.

- All of the enterprise’s quality certification documents, including numerous authoritative system certification certificates, recognition qualifications for high-tech and specialized, refined, distinctive and innovative enterprises, third-party product reliability test reports, intellectual property patent certificates, environmental compliance test materials and more, are authentic, valid and verifiable. The company continuously upgrades its quality control standards and testing schemes, strictly abiding by industrial specifications for semiconductor packaging and testing as well as automotive sensors. Through systematic control and transparent qualification disclosure, it supplies integrated circuits and sensor modules with stable performance and full compliance to customers in the industrial, automotive and imaging sectors.
