Electronics Assembly Training Guidance and Analysis Abstract: Training needs of students in electronics manufacturing a solid theoretical foundation, excellent operational skills, which are knowledge and ability to obtain the required electronic components, circuit structure and principle, failure analysis, and a variety of proficiency testing means and methods for integrated utilization of capacity, namely, points, paragraphs, lines. Keywords:: electronic components; assembly; testing; Skills With the reform of vocational schools, the continuous progress of professional courses, vocational schools have become increasingly focus on students in hands-on abilities, students hands-on opportunities for more and more. However, the author led the students in the production and maintenance of electronic small electrical skills identification when found some problems. The existence of these problems are mainly due to the students basic knowledge is not solid, good hands, can not properly use what they have learned and analyze problems and solve the problem caused. So, how can we enable students to master basic skills, basic knowledge and enhance their practical ability, as well as analyze problems and problem-solving capacity? I summarized these as the points, paragraph, line three areas. Points: the various components of the structure, principles and role of Figure 1, Figure 2, the circuit includes a variety of commonly used electronic components: diodes (including regulator diodes), transistors, capacitors (electrolytic capacitors), resistors, SCR, Single-junction transistors. These transistors (including diodes, transistors, SCR, single-junction transistor) are P-type and N-type semiconductor material composition, in structure by the structure into a different number of PN, its role is different. Diodes is mainly used for limiting, rectifier; transistor for current amplification; silicon (crystals thyratron) is used to control the strong power of a semiconductor de
