摘 要 电子工艺实训是电子、通信相关专业的重要实践课程,能让学生掌握电路的设计与制作。针对目前电子工艺实训仍采用传统印制电路板工艺,导致学生对电路制作新工艺(如表面贴装工艺、增材制造技术)不熟悉的问题,提出将新型增材制造技术引入电子工艺实训课程中。传统印制电路板工艺与新型增材制造技术的有机结合,能让学生在掌握传统电路制作工艺的同时,弥补表面贴装工艺环节的缺失,掌握新型电路制作技术,提升创作空间。

Introduction of Additive Manufacturing Technology in Electro-nic Technology Training//YAN Xiaohei, HUANG Shexin, FANG Hui
Abstract Electronic technology training is an important practical course for electronic and communication related majors, which ena-bles students to master the design and production of circuits. Aiming at the problem that students are not familiar with the new technologyof circuit making (such as surface mounting technology and additive manufacturing technology) because the traditional PCB technology is still used in the current electronic technology training, this paper proposes to introduce the new additive manufacturing technology into the electronic technology training course. The organic combina-tion of traditional PCB technology and new additive manufacturing technology can help students master the traditional circuit manufac-turing technology, make up for the lack of surface mounting techno-logy, master the new circuit manufacturing technology, and improve the creation space of students.

电子工艺实训课程是电子、通信相关专业的重要实践课程,着重培养学生的电路设计能力和实际动手制作能力。该课程运用电子技术课程学习成果,进行从简单到复杂电路的设计与制作,并在电子生产流水线上进行实际焊接及装配、调试,完成理论与生产实际的有效结合[1]。
1 电子工艺实训课程现状
目前,大部分高校的电子工艺实训课程采用的流程为:基本元器件认知→焊接工艺训练→实训项目选取并进行电路设计→电路板制作→元器件焊接安装→整体电路调试[2]。其中电路板制作主要采用传统的印制电路板工艺,具体使用较多的是热转印法,该法对批量生产相同电路板效率较高,因此在生产上被广泛使用。让学生掌握此电路板制作方法很有必要,但此法工序较为复杂,学生实训时选择的实训项目各不相同,电路板亦不同,导致制作耗时长。……
