"Shenzhen Xingweifan Electronic Technology Co., Ltd. was established in 2000. It is a high-tech enterprise integrating the design, production and development of semiconductor products (including ICs and modules). It is a member of the Shenzhen Semiconductor Association. The company has experienced development engineers and application engineers who are committed to the research and development and technical support of the company's independent intellectual property IC and other products. It has developed a number of mature products and mass-produced, sold and exported them, including chip products SD0418 and SD2000. It has been included in the books "MCU Peripheral Circuit Design" and "EM78 MCU Practical Tutorial" published by Electronic Industry Press; our company's high-precision real-time clock module products have obtained a number of national patents, breaking the long-term monopoly of foreign products. status, and product performance parameters are better than those of foreign companies; our company's independent IC has been registered by the State Intellectual Property Office. Our company also wrote the first book in mainland China that introduces ELAN microcontrollers in detail, "EM78 Microcontroller Application Technical Manual". The company has passed ISO9001:2015 international quality system certification and IATF 16949:2016 automotive industry quality management system certification. The company has always been adhering to the business philosophy of "integrity-based, quality first" and always runs through the entire design, production, During the procurement and sales process, we follow the requirements of the ISO9001 standard and establish a quality management system in which the company's quality department is responsible for everything from purchasing, product inspection, 6S management in the production workshop, and shipment inspection to all employees' participation to prevent fakes. , the entry and exit of defective products to ensure that users are provided with quality products. In order to strengthen inspection methods, we are specially equipped with electromagnetic compatibility testers (±4KV group pulse generator), high and low temperature alternating test chambers (-40℃∽+ 85℃), digital storage oscilloscope, wideband LCR digital bridge, ultra-high precision frequency meter (±0.03ppm), IC tester and other experimental equipment; in order to further strengthen the control of product quality, the company introduced a new SMT reflow sticker Chip welding lines, fully automatic chip testing machines, automatic packaging machines, and laser machines basically realize the automation of production equipment and achieve the goal of refined management of the entire product production process.
