李四一拿着值班电话在fab外的办公室坐着，处理一些邮件。正当李四一拿着水杯接水的时候，口袋里的值班电话响了起来，凤凰传奇的最炫民族风，很有激情的一首歌，李四一打算把水接完，再回过去，看着水杯里的水一点一点地上涨，直到装满，李四一按下了停止键，把水杯的盖子盖上了。正当李四一想把手机拿起接电话，电话又没响了，李四一看了一眼电话，是产线制造部打过来的，李四一回了过去，说是有一台机器down了，冒红光了，让李四一快马加鞭进去看看，李四一听着里面嘈杂的机台报警声，天车运行的声音，放佛都在催着他进去。李四一喝了一口水，把水杯放到了办公桌上，背上无尘包，往fab走去。fab里面人还挺多的，各种维修，自从公司没了厂商的帮助，机台就经常出问题了，因此里面维修的人员也是很多见的。李四一来到他主管的设备跟前，看着屏幕上的报警，显示机台过热，李四一一看旁边的风机的风扇，停止了转动，李四一试者把开关重新开关了一下，风机还是没反应。大概就是这个散热风机坏了吧。李四一和制造部确认了wafer的数量和位置，先把wafer给退了出来，看着最后一片wafer回到Foup，李四一这才放心地把机台给下电了，李四一担心温度再这么升上去，把什么电路板上的元器件给烧坏掉。李四一准备去仓库领了个风机过来，确认了料号之后，李四一就开始拆装，风机更换不是特别难，李四一没过多久就换好了，接好了线，一开电，风机也转了起来，机台也看着能够正常运转了，制造部匆匆地催李四一还机，李四一就赶紧还了，他还想出去上个厕所呢！李四一在卫生间上着厕所呢，电话又响了，李四一差点没抓住手机，掉坑里了。电话那头还是制造部，说是机台又有问题了，还闻到了烧焦的味道，李四一让他们赶紧按EMO,制造部说他们不按，怕担责任，李四一无奈地说，你录音吧，有什么问题责任我来承担，赶紧按，别待会儿整个fab都烧着了。李四一让他们赶紧按EMO,制造部说，不用我们按了，机台自己跳电了。李四一急忙往fab里赶。确实有一股烧焦的味道，李四一打开机台的面板，一看果然有块电路板烧了一个角了。李四一检查了一下，就那块电路板，和两个街头烧了，其他也没什么了。李四一又去检查了一下风机，结果发现风机装反了，本来要散热的，应该是热量散不出去，导致电路板一直发热，烧坏了。李四一只好去仓库找一下这块电路板和接头，还好是有，李四一抓紧给换上，李四一把电路板和接头换了，又把风机重新安装了一下，就好了。机台也算是顺利开起来，初始化也成功了。李四一在fab里面等机台跑了半个小时，看到没问题了，就走出了fab.出来的时候，天已经黑了，领导还在工位，问了一下李四一什么情况，李四一一五一十地讲述了一下，领导让李四一块去吃饭，修好了就行，食堂应该也没饭了，李四一便点了个外卖，写了个报告的间隙，外卖就到了，李四一点了发送，就去拿外卖了。午晚饭，还是挺香的，李四一坐在厂门口的马路牙上，吃着外卖，厂门口亮起的半导体厂牌照在李四一的身上，旁边也有许多和李四一一样，修机修到现在才吃饭的工友……Li Siyi was sitting in the office outside the fab with the on-call phone, processing some emails. Just as Li Siyi was holding a water cup to get water, the on-call phone in his pocket rang. It was the most dazzling folk style song of Phoenix Legend, a very passionate song. Li Siyi planned to get all the water and then go back. Watching the water in the cup rise little by little until it was full, Li Siyi pressed the stop button and closed the lid of the cup. Just as Li Siyi wanted to pick up the phone to answer the call, the phone didn't ring again. Li Siyi took a look at the phone. It was from the production line manufacturing department. Li Siyi called back and said that a machine was down and emitting a red light, so Li Siyi was asked to go in and take a look. Li Siyi listened to the noisy machine alarm and the sound of the overhead crane running, as if they were urging him to go in. Li Siyi drank a sip of water, put the cup on the desk, put on the dust-free bag, and walked towards the fab. There are quite a lot of people in the fab, doing all kinds of repairs. Since the company lost the help of manufacturers, the machines often have problems, so there are many repair personnel inside. Li Siyi came to the equipment he was in charge of and looked at the alarm on the screen, which showed that the machine was overheating. Li Siyi looked at the fan of the blower next to it and found that it had stopped turning. Li Siyi tried to turn the switch back on and off, but the blower still didn't respond. Maybe the cooling fan was broken. Li Siyi confirmed the number and location of the wafers with the manufacturing department, and took the wafers out first. After watching the last wafer return to the Foup, Li Siyi safely turned off the power to the machine. Li Siyi was worried that the temperature would rise again and burn out the components on the circuit board. Li Siyi was going to the warehouse to get a fan. After confirming the material number, Li Siyi began to disassemble and assemble it. It was not particularly difficult to replace the fan. Li Siyi replaced it in a short time, connected the wires, and turned on the power. The fan also started to rotate, and the machine seemed to be able to operate normally. The manufacturing department hurriedly urged Li Siyi to return the machine, and Li Siyi returned it quickly. He also wanted to go out to the bathroom! Li Siyi was in the bathroom when the phone rang again. Li Siyi almost didn't catch the phone and fell into the pit. The manufacturing department was still on the other end of the phone. They said that the machine had problems again and smelled a burning smell. Li Siyi asked them to press EMO quickly. The manufacturing department said they would not press it because they were afraid of taking responsibility. Li Siyi said helplessly, you record it, I will take responsibility for any problems, press it quickly, otherwise the whole fab will burn. The manufacturing department questioned, is this a fire bomb? It can burn so much. Li Siyi asked them to press EMO quickly, and the manufacturing department said, we don't need to press it, the machine has tripped by itself. Li Siyi hurried to the fab. There was indeed a burning smell. Li Siyi opened the panel of the machine and saw that a corner of a circuit board was burnt. Li Siyi checked and found that only the circuit board and two corners were burnt, and nothing else was burned. Li Siyi checked the fan again and found that the fan was installed upside down. It was supposed to dissipate heat, but the heat could not be dissipated, causing the circuit board to heat up and burn out. Li Siyi had to go to the warehouse to find the circuit board and connector. Fortunately, they were there, so Li Siyi quickly replaced them. Li Siyi replaced the circuit board and connector, and reinstalled the fan, and it was fine. The machine was started smoothly and the initialization was successful. Li Siyi waited for the machine to run for half an hour in the fab. When he saw that there was no problem, he walked out of the fab. When he came out, it was already dark. The leader was still at his workstation and asked Li Siyi what happened. Li Siyi told him everything. The leader asked Li Siyi to go to eat together. It would be fine as long as it was repaired. There should be no food in the cafeteria. Li Siyi ordered a takeaway. While he was writing a report, the takeaway arrived. Li Siyi clicked the delivery button and went to get the takeaway. Lunch and dinner were still very delicious. Li Siyi sat on the curb at the factory gate and ate the takeaway. The semiconductor factory license plate lit up at the factory gate was on Li Siyi. There were many workers like Li Siyi who had been repairing the machine until now and had not eaten yet...
