1.Management System Certification
ESD Electronics Co., Limited. (hereinafter referred to as ESD) has successively obtained ISO9001 quality management system certification, ISO14001 environmental management system certification, product CCC certification, and product energy-saving certification. The entire quality and environmental control system of ESD is mainly based on the requirements of GB/T 19001-2016/ISO 9001:2015 Quality Management System Requirements, GB/T24001-2016/ISO 14001:2015 Environmental Management System Requirements and Guidelines for Use, CNCA-00C-005 Implementation Rules for Compulsory Certification Products Factory Quality Assurance Capability Requirements, and CQCF002-2009 Factory Quality Assurance Capability Requirements for Resource-Saving Product Certification, etc. Based on the company's own size and operation mode, ESD has established a systematic quality management system and environmental management system to ensure the consistency, reliability, and traceability of product production. The company's system certification and product certification are internally audited once a year and externally audited three times (surveillance audit), and are continuously improved based on changes in standards, market development, and company adjustments, effectively ensuring the continuity, effectiveness, and suitability of the entire management system.
1.1 Quality Management System Certification
Quality management system certification refers to the evaluation of an enterprise's quality management system by a third-party certification body qualified to obtain quality management system certification, based on the formally released quality management system standards. Qualified certification is issued by a third-party agency and registered and published to prove that the company's quality management and quality assurance capabilities meet the corresponding standards or have the ability to provide products according to the specified quality requirements. The quality management system is the foundation for systematically and step-by-step improving the company's major quality activities in order of importance.
1.2 Environmental Management System
Environmental management system certification refers to the evaluation of the environmental management system of a supplier (manufacturer) by a third-party notary organization based on publicly released environmental management system standards (ISO 14000 series standards). A certificate of environmental management system certification is issued by a third-party organization for qualified evaluations, and registered and published to prove the supplier's environmental assurance capability in accordance with established environmental protection standards and legal requirements for providing products or services. Through environmental management system certification, it can be verified whether the raw materials, production processes, processing methods, and use and disposal of products used by the production plant comply with environmental protection standards and regulatory requirements.
2.7 Reliability testing
Reliability testing is an activity conducted to evaluate the ability of a product to maintain its functionality over the specified lifespan, under expected conditions of use, transport, or storage, and in all environmental conditions. It involves exposing the product to natural or artificial environmental conditions to evaluate its performance under actual conditions of use, transport, and storage. Various environmental test equipment is used to simulate temperature extremes, humidity, and temperature variations in the climate, among other conditions, to accelerate the product's response to environmental conditions and verify that it meets the expected quality goals during development, design, and manufacturing, thus evaluating the overall product and determining its reliability lifespan.
2.7.1 Physical reliability
This includes physical reliability testing such as high and low temperature, drop testing, and simulated transportation vibration. During the product selection and prototype phase, relevant physical reliability tests are performed on the product according to GB/T 9813.3-2017 "General technical specifications for computers-Part 3: Servers" to verify the compliance of the results.
2.7.2 Reliability Testing (Load)
In terms of full load testing, we conduct full load performance tests on CPU, memory, hard drive, graphics card, RAID card, network card, etc. The tests mainly include using tools such as STRESS, memtest, FIO, iozone, iperf, netperf, CUDA, spec, GPUbrun, etc. We use STRESS and memtest to conduct at least 48 hours of stress testing on memory, STRESS and spec to conduct performance stress testing on CPU, FIO and iozone to conduct read/write and random read/write performance testing on hard drives, netperf and iperf to conduct transmission testing on network cards, and install CUDA and use GPUBrun to conduct performance and stress testing on graphics cards. Through the above tools and methods, we conduct reliability testing on the entire server under full load to verify whether the server's reliability under full load meets the standards.
4.Equipment Management
In order to strengthen the maintenance and upkeep of equipment, standardize management and procedures, and further improve work efficiency, the company has established the "Equipment Maintenance and Upkeep System" and established records including equipment inventory, equipment maintenance logs, and inspection equipment calibration records. The goal is to ensure correct usage, careful maintenance, and timely repair of equipment, so that equipment can operate safely and stably for a long period of time, and production can proceed smoothly.
4.1 Production Equipment
The company currently has one automated production line and one fully intelligent production line, as well as other production equipment, including one automatic packaging machine, one automatic screw machine, and one automatic assembly robot, achieving full human-machine collaboration assembly line production with a daily output of 400 units.
