Wuxinbin, communication repair technician of a brigade of the 73rd group army—— Deep grinding and fine grinding of "0.5mm" ■ wangmengyuan, zhaozhenyi Standing on the podium of the army's "ingenuity Cup" equipment maintenance competition, wuxinbin, a first-class staff sergeant of the second repair company of a brigade of the 73rd group army, was in a trance for a while. He didn't expect to be able to step on such a big stage with his "small skills". How small is wuxinbin's craft? As a communication repair technician, the largest electronic communication components he has repaired are just like fingernails, and the smallest ones are only slightly thicker than hair, with a diameter of only 0.5mm. At first, many repairmen also studied repair technology with wuxinbin. However, with the installation of new equipment, the integration of communication equipment modules became higher and higher, and the electronic components became smaller and smaller. Some people chose to "retreat from difficulties", but wuxinbin did not believe in this evil. "These components are usually repaired by the manufacturer when they are broken. If they are broken in major activities, they can be directly replaced by the standby module. Why do you have to take so much effort?" Some comrades in arms did not understand wuxinbin's practice. "The manufacturer can't guarantee that it can come at any time. In practice, the spare module has a rationing base, and it will always be used up." Wuxinbin insisted, "even though the probability of these two situations occurring at the same time is not large, I am a communication repair technician and must consider these issues!" In order to prevent the possibility of an accident, more than 10000 efforts must be made. Small components, especially those with a minimum diameter of only 0.5mm, are far more difficult to repair than expected, and difficulties have emerged in front of wuxinbin. The first is "tool off". The components were too small for the naked eye to see, so he found a headlamp and a magnifying glass. The original tool was too big to use, so he modified it by himself, welded the sewing needle to the pen tip of the multimeter, ground the copper core and connected it to the soldering head of the electric soldering iron, which solved the problems of detection and welding. Then there is "gimmick off". The components are small, and the solder joints of the pad are also small. It is necessary to be stable, accurate and fast during clamping, placing and welding. Wuxinbin tried to improve his operating skills: others sewed clothes with needles and threads. He used needles and threads to wear rice grains, often puncturing his fingers. In order to simulate the tense state under actual combat conditions, he ran into the workshop after physical training from time to time and picked up tweezers to "open a small stove". The second is "proficiency level". In order to practice makes perfect, wuxinbin not only went to the scrap car factory to dismantle all kinds of usable circuit boards for practice, but also looked for a mobile phone training meeting around his comrades in arms. He has repaired earphones, electric doors, induction cooker, etc. After a period of exploration, he also formulated training and assessment standards for himself: for 0.5mm components, welding 20 components takes 60 seconds to be excellent, 70 seconds to be good, and 80 seconds to pass With his extraordinary perseverance, wuxinbin has overcome three difficulties. His hands are scarred and calluses are connected one by one, which makes people feel distressed. As a result, his repair technology has become increasingly sophisticated. Whenever there is a problem with components, he can always "get rid of the disease at hand". The highlight moment belonging to wuxinbin is coming again. In the single car continuous comprehensive drill just completed by the brigade, a shock car radio broke down suddenly. Wuxinbin rushed to the scene. In a dark and narrow environment, he took out a tool kit to quickly detect and replace it. In less than 5 minutes, the fault was eliminated. All the people present gave him a thumbs up. In a word, the award speech: the wonderful performance on the big stage comes from the hard work in a small space. It is this persistent pursuit of "craftsman spirit" that sharpens the "edge" of a top soldier. (outlook new era)
