中法联合学院2017级

学生专业实训

前言

      东莞理工学院法国国立工艺学院联合学院以应用型、国际化的办学特色为宗旨，注重学生实践创新能力的发展。为了让学生深化对专业知识的了解，进一步提升专业技能，本学期18、19、20周，中法联合学院2017级通信工程、软件工程、机械设计制造及其自动化3个专业学生相继举行专业实训。实训的内容包括电子工艺、智能小车、3D打印、微信小程序设计、安卓APP设计、流水线作业，共6个。

     通信工程专业（Communication Engineering）的实训内容安排共分3个，分别是电子工艺、智能小车、流水线作业。

电子工艺实训

     第18周，2017级通信工程专业实训的内容是电子工艺，实训课题是焊接组装摇一摇LED幸运转盘、JC210SP型调频调幅收音机和单片机流水灯数码时钟。

      电子工艺实训课程内容，主要由以下几个部分组成：1）摇一摇LED幸运转盘焊接，成品具有震动传感器和随机亮灯功能；2）收音机焊接组装，成品具备AM和FM调谐和音量控制功能；3）单片机流水灯时钟焊接组装，成品具备流水灯、日期、时分秒显示和音乐闹钟功能。

      电子工艺的考查部分有以下内容：1）功能实现，检查LED幸运转盘、收音机和单片机时钟是否实现了功能；2）焊接工艺，检查焊点是否饱满、规范。

The contents of the electronic process course were as follows: 1) LED lottery draw plate soldering – the product had shock sensors and random stop functions; 2) Radio circuit soldering and assembly – the radio had AM and FM tuning function; 3) MCU-controlled LED clock soldering and assembly – the product had an LED light display, date, time and music alarm functions. This course included checking the function of the LED plate, radio and clock and ensuring that the circuits were all properly soldered.

学生心得体会

黄同学

      通过这次实训，我们学会了基本的焊接技术，焊接了幸运转盘，收音机，简易圆形时钟。同时我们还学会了电子元器件的识别以及质量检验，学习了整机的装配工艺，这些都培养了我们的动手能力及严谨的作风，锻炼了自己的动手技巧，提高了自己解决问题的能力，也为我们以后的工作打下了基础。

Through this training, we learned the basics of soldering by applying these skills on LED lottery draw plate, radio, and a simple circular clock. At the same time, we also learned to identify different electronic components, to carry out quality inspection, and how to assemble machines. This allowed us to cultivate our practical abilities and to learn the importance of being rigorous, as well as improving our ability to solve problems. Together these skills help lay a good foundation for our future careers.

     在实训过程中，我们主要学习了如何焊电路板。我们制作出了闹钟，收音机和摇一摇。虽然接受实训的时间还很短，但是我已经感觉受益匪浅。焊电路板其实并不需要什么技术性的知识，但是很锻炼一个人的耐心和细致。我自己在焊电路的时候，刚开始也会出现非常多的错误，比如将用电元件焊在电路的覆铜面上，或者接芯片时芯片的缺口没有与覆铜面上示意图相同， 再比如因为一开始缺乏经验和耐心，虚焊的情况也是经常发生的。 这些都让我越发感觉到对于一个工科学生而言，严谨，认真和耐心是非常重要的。

During the training process, we mainly focused on learning how to solder circuit boards. We made alarm clocks, radios and LED plate. Although the training time was quite short, I felt like I benefited from it a lot. Soldering a circuit board actually does not need much technical knowledge, but requires that you are patient and meticulous. When I soldered the circuit, I made a lot of mistakes at the beginning, such as welding the electrical components on the copper clad surface of the circuit, and not ensuring that the chip’s gap was the same as the schematic diagram of the copper clad surface. Due to my lack of experience and patience at the beginning, virtual welding also happened frequently. However, by making these mistakes I learned to appreciate that rigor, seriousness and patience are very important for an engineering student.

     通过这次实训，我发现在实际操作中会遇到很多问题，比如说焊脚没焊牢固导致整个电路无法运行，或者是焊接的时候不小心将电路板里的铜丝挑断了,需要飞线来拯救，这都是平常在书本上学不到的。一件成品做的好坏不仅在于它是否能运行，还包括了这件成品的工艺是否完美，所以我们的焊锡技术也在这几天中得到了提高。同时安全问题也是我们很需要重视的，特别是在不用焊机的时候要养成随手关电源的习惯，还有不要在实验台上放自己的私人物品，特别是水杯，以免引起火灾或者是其它灾难。

Through this practical training, I encountered many practical problems, such as the failure of soldering feet resulting in the whole circuit being unable to run, and accidentally picking out the copper wire in the circuit board and needing floaters to save the circuit. These are the kinds of mistakes which are not easy to learn from books, so this course helped us improve our practical understanding of soldering. It also taught us that the quality of a product is judged not only on whether it can work, but also on whether the product process is perfect. At the same time, this course taught us to pay attention to safety issues, such as developing the habit of turning off the power supply to the soldering iron when it is not in use and not leaving personal items on the laboratory table, especially cups of water, in order to avoid fire or other disasters.

老师寄语

    通过为期一周的电子工艺实训课程，丰富了同学们对PCB、电容电阻、传感器、单片机、LED等电子电路的知识，了解了电路专业知识的应用，大大提高了同学们的工程实践能力，提升了对科技的兴趣，为以后的电子竞赛和科研打下良好的基础。

After the one-week-long electronic process course, the students have learned about PCB, resistors, capacitors, sensors, MCUs, and LEDs. The course helped them to understand the engineering applications of the electric circuit theory and it improved their practical abilities. This course provided a good beginning for their engineering careers.
