■Introduction of Xiangxin Electronics

       Shanghai Xiangxin Electronics Company is a manufacturing company engaged in the development and testing of consumer integrated circuits (ICs). Opened in December 2004, it is located in Bailangyu Square, Yangpu District, Shanghai. We have a group of senior R&D personnel who have been engaged in IC design for many years. We have a processing base in Jiading District, Shanghai, and a group of IC test engineers with many years of experience. The company takes quality first. The clean room design and construction project entrusted to our company Shanghai Tobetter has been highly evaluated by Xiangxin Electronics and Xiangxin Electronics' customers at the same time. The clean room area entrusted to Xiangxin Electronics is about 7000 square meters, among which there are class 100 and class 1000 clean rooms of nearly 3000 square meters. With high product quality, good production environment and standardized production management, Xiangxin is in the forefront of the industry.

■ Cleanroom clean room project completion acceptance of the commissioning of the preparatory work before

1, the clean room purification project commissioning organization preparation：

成立以建设单位（业主）为组长的有设计单位、施工单位、监理单位人员参加的调试小组。调试小组领导调试的全面工作，调试小组协调各方面的关系，调试小组为调试工作提供各种软硬条件。

2、Commissioning outline of clean room purification project preparation

Under the leadership and organization of the commissioning team, the commissioning outline is prepared. Commissioning outline is the guiding document of commissioning work. The content of the commissioning outline includes: organizational division of labor, material mobilization; commissioning project, commissioning method, commissioning instrument; commissioning procedure, commissioning progress, commissioning plan arrangement, etc. The preparation of the commissioning outline makes the commissioning personnel clear in mind, unified in understanding, consistent in pace and neat in action, so that the commissioning work is carried out smoothly.

3、The clean room construction site quality of the clean room will be inspected.

Under the leadership organization of the commissioning team, relevant leaders and technical personnel of construction unit, design unit, construction unit and supervision unit participated in the construction site and construction quality for a comprehensive meeting inspection. From the refrigeration station, heat exchange station, boiler room, substation and distribution station, air conditioning machine room to the cooling, heating, power supply system, air conditioning purification system and automatic control system. From the construction quality of equipment (freezers, boilers, pumps, cooling towers, air conditioners, etc.), fittings (valves, air outlets, mufflers, etc.), pipes and pipelines to insulation, equipment foundations, pipe supports and hangers, etc. will be fully inspected. To see whether the construction according to the map, check and design drawings do not match the place, to find the construction quality of unqualified items and check the reasons. And the construction, processing, installation and other quality issues one by one to fill out “ defect schedule ”, put forward rectification advice, the deadline (before the official commissioning) rectification completed.

4、Clean room purification project of the air conditioning equipment, air conditioning system cleaning：

① It is very necessary to carry out a comprehensive and thorough cleaning of the clean room before commissioning. The ground, wall, ceiling, doors and windows of the clean room should be carefully, comprehensively and thoroughly cleaned (it is better to ask professional cleaning company); the air conditioning equipment, air conditioning ducts (air supply duct, air return duct, new air duct), air conditioning accessories (cleaners, valves, air outlets, etc.) should be checked, leak detection and wipe test. Until the clean requirements are met.

②Install coarse and medium-effect filters for the first air blowing. On the basis of thorough cleaning, install the coarse and middle-effect filters in the air conditioner. Air-blowing of the whole purified air conditioning system, air-blowing time is 24~36 hours, so that the whole system can be initially purified.

③Installation of high efficiency filter. High efficiency filter can be installed after the system is air blown. Before the installation of high efficiency filter, it is required to leak detection one by one, and plugging for those who have leaks. Leak detection is carried out on the temporary leak detection table, and the dust source uses atmospheric dust. The high efficiency filters that are qualified can only be installed, and after installation, the installation seal of the high efficiency filters will be tested for leaks again (using dust particle counter scanning) to achieve qualified installation.

④High efficiency filter installation leak detection after passing the second air blowing on the purified air conditioning system. The air blowing time is 24 hours, and then the commissioning procedure can be carried out.

5, clean room purification project test instruments, meters, tools for the preparation

① The instrumentation used in the commissioning should be debugged and calibrated before the commissioning (over the use of time also need to be re-calibrated). The instruments used include instruments for measuring air speed, air volume, temperature, relative humidity, differential pressure, noise, vibration, rpm, time, atmospheric pressure and cleanliness, etc.

② debugging equipment and tools used in the preparation. Such as: electrician's tools, plumber's tools, metalworker's tools, pliers' tools and ladders for climbing up and down. And ask the construction unit to cooperate with electricians, plumbers, metalworkers and pliers.

③ Preparation of drawings and record forms used for commissioning and testing work.
