Most of the welding jobs are for men, and the "80s" lady with a baby face and gentle looks is an aerospace "welding".
Her name is Wang He, 36 years old. She is a hand-welded worker at the Denso Optical Precision Machinery and Physics Institute of the Chinese Academy of Sciences (hereinafter referred to as the "Changchun Institute of Optics"). Over the years, she has participated in the manufacture of more than a dozen space-space load projects such as the famous Shenzhou series, Tiangong series and 嫦娥 series, which have made an indelible contribution to the development of China's space industry.
"PCB (printed circuit board) is like the brain of a spacecraft. My job is to solder components to the board and ensure that they meet the highest international standards." When talking about his work, Wang He’s tone It is a pride that cannot be concealed.
This work is very simple to say, but if you compare ordinary welding to sewing clothes, Wang He's work is the most exquisite "embroidery". "It is not difficult to weld a qualified solder joint. It is difficult to achieve the standard all the time." Wang He said that the first point of aerospace products is to require high reliability, and the value of aerospace products is expensive. A small mistake can lead to hundreds of millions of yuan. A major loss.
"I have contacted thousands of devices and tens of thousands of devices. The soldering requirements of each device are different, and each solder joint must be accurate." Wang He told reporters: "Aerospace PCB can be detected with high magnification magnifier and X-ray. Solder joint quality, but many welding processes can not be tested, all rely on the solid theoretical foundation of the welder, skilled welding technology and a high degree of responsibility to protect."
Therefore, Wang He believes that the most important thing to do in this job is to have a high sense of responsibility and care. In every day's work, she is on thin ice, only the product in her hand is successfully launched, and the stone in her heart can fall a little.
In 2008, after two years of study and accumulation, Wang He began to participate in the PCB welding task of the Tiangong series of spacecraft. "This process is both painful and valuable!" Wang He told reporters that at the time she refused to accept the sweetness of her new marriage and plunged into the project...
When the "Tiangong" was successfully launched, Wang He had a feeling that he couldn't tell: "It seems that I have raised a child. I watched her grow up a little. I felt that all the sufferings were worth it. I have no regrets in my life. â€
Wang He, who masters the aerospace PCB soldering and rework technology, has been able to operate highly reliable soldering of all components on aerospace PCB products. Of the nearly one million solder joints she completed, none of the failed solder joints. What is even more unimaginable is that because of her supreme pursuit of perfection, the solder joints she completed are all exquisite and exquisite. As long as the inspection experts saw these solder joints, they all knew that they were from the hands of Wang He.
"China's aerospace industry has been developing, more and more new processes, and more and more technical difficulties. What we can do is to forget the past, work hard, and run with a normal heart." Wang He said .
In the face of difficulties, Wang He always had a special tenacity. This quality also helped her to make up for some of the design flaws of the process itself and saved incalculable losses.
"As long as you think, there will always be a way." In one mission, due to operator error, multiple PCB pads fell off, not only the equipment of several million yuan was scrapped, but the progress of the project was also seriously affected. At this critical juncture, Wang He stepped forward. After two days and two nights of research, he found a unique rework process, which quickly repaired the PCB and was highly evaluated by the project leader.
Due to the special nature of the work, Wang He missed the colorful life of a woman of the same age since she entered the business, but she never regretted it. "Because of the confidential nature of the work, many achievements and honors cannot be made known to others. I am a normal woman in the eyes of others, but I know how great my career is." Wang He said with a smile: "I thought already The aerospace products that have been successfully launched are playing a role in space, and I am particularly excited and happy, and I am proud of it."
