Kunshan Youmao Electronics Co., Ltd. may ensure the stability of connector products through the following methods:

Strict raw material control:

Supplier screening: The company will carefully select raw material suppliers and choose those suppliers with reliable product quality and good reputation to cooperate. Conduct strict evaluation and review of suppliers, including their production qualifications, quality management systems, product testing reports, etc., to ensure that the purchased raw materials meet the company's quality standards.

Raw material inspection: Strict inspection and testing of each batch of raw materials. For example, testing the conductivity, hardness, corrosion resistance and other performance indicators of metal materials, and the heat resistance, insulation, mechanical strength and other indicators of plastic materials. Only raw materials that pass the inspection can be put into production to ensure the stability of the product from the source. .

Precise production process control:

Advanced production equipment: Equipped with advanced production equipment and automated production lines to ensure the accuracy and stability of the production process. For example, high-precision injection molding machines, stamping machines, mold processing equipment, etc. are used to ensure the dimensional accuracy and structural stability of the connector. At the same time, automated production lines can reduce the impact of human factors on the production process and improve production efficiency and product quality consistency.

Process parameter optimization: Develop detailed production process flow charts and process parameter standards for different types of connector products. Through continuous testing and optimization, the best process parameters, such as injection molding temperature, pressure, time, stamping speed, strength, etc., are determined to ensure the stability of the production process and the reliability of product quality.

Quality monitoring point setting: Set up multiple quality monitoring points during the production process to monitor and inspect key processes and key components in real time. For example, key performance indicators such as connector pin insertion force, extraction force, and contact resistance are tested online. Once an abnormality is discovered, the production process is adjusted or the machine is shut down in a timely manner to avoid the production of defective products.

Strict quality inspection system:

Comprehensive testing items: Establish a complete quality testing system to conduct comprehensive testing and testing of connector products. Including appearance inspection, such as checking the surface finish of the product, whether there are defects, scratches, etc.; dimensional inspection, ensuring that the size of the product meets the design requirements; performance inspection, such as withstand voltage test, insulation resistance test, contact resistance test, and electrical continuity between shells Sexuality testing, etc.

Combination of random inspection and full inspection: Based on the batch size and importance of the product, a combination of random inspection and full inspection is used for quality inspection. For products with larger batches, random inspections are carried out according to a certain proportion; for products from important customers or key application fields, full inspection is carried out to ensure that every product meets quality standards.

Calibration of testing equipment: Calibrate and maintain quality testing equipment regularly to ensure the accuracy and reliability of testing equipment. Use standard samples to calibrate testing equipment, establish equipment calibration files, and record equipment calibration time, calibration results and other information for traceability and management.

Product design optimization:

Rational structural design: During the product design stage, fully consider the usage environment and application scenarios of the connector and conduct a reasonable structural design. For example, use reliable connection methods, such as snap-on, threaded, etc., to ensure that the connector will not loosen or fall off during use; optimize the internal structure of the connector, improve pin arrangement accuracy and contact stability, and reduce signal Transmission interference and losses.

Material compatibility design: Considering that the connector may come into contact with different electronic devices and materials, pay attention to material compatibility when designing. Choose materials that are compatible with other materials to avoid chemical reactions or physical interactions between materials that may affect the performance and stability of the connector.

Employee training and management:

Skills training: Conduct regular skills training and assessments for production front-line employees to improve their operational skills and quality awareness. The training content includes production technology, equipment operation, quality inspection, etc. to ensure that employees are proficient in production technology and quality control methods, and produce in strict accordance with operating procedures.

Quality management training: Provide professional quality management training to quality management personnel so that they can master advanced quality management concepts and methods, such as Six Sigma, lean production, etc. Improve the professional level and management capabilities of the quality management team to ensure the effective operation of the quality management system.
