It may be that the new machine is turned on, because the circuit board suddenly conducts electricity leading to a place contaminated with a small part of the material softening, if there is painting, it will emit burnt taste, this rarely happens, in this case can be directly ignored.
May be caused by the high temperature of the mobile phone battery, try the following solution: the mobile phone in use or charging, there is a burnt taste, immediately stop using the mobile phone. Then take the mobile phone, invoice and warranty card to the local brand customer service test as soon as possible, and the customer service engineer will find out the problem of the mobile phone after testing the mobile phone. The warranty period of the phone is 1 year, if the phone is guaranteed and it is a natural failure,. Students are required to practice and master the correct method of welding, familiar with the choice of welding tools and welding materials. And understand the development of electronic welding technology in industrial production, welding process and assembly machine production process. Students are required to master the assembly, welding and debugging of the radio. Basic operating skills, and the production, installation, commissioning and testing of actual products.
Through two weeks of electronic practice, I have a certain perceptual and rational understanding of electronic components and radio installation and debugging, laying a good foundation for the future study of electronic technology courses. At the same time, the internship allowed me to get the real charger and radioInternational production knowledge and assembly skills have cultivated my ability to combine theory with practice, improved my ability to analyze and solve problems, and enhanced my ability to work independently.
Electronic Technology Training Room (1) Practice Purpose Through the installation, welding and debugging of HX203FM/AM integrated circuit telephone set in this project design, students can understand the assembly process of electronic products; Learn the assembly process of the whole machine; Cultivate practical ability and rigorous work style.

2. Summary Report of electrician Practical training Purpose This practical training is an application-oriented course integrating knowledge, quality and skill training. It is based on the use of relevant electrical theories and at the same time, the basic quality and skills of electricians have been comprehensively used to cultivate, through practical training, studentsWith the basic ability of junior electricians, can meet the comprehensive needs of enterprises for junior electricians. (1) Through a week of practical training, I feel that I have gained in the following aspects: Training purpose Through a week of electrical training, so that I have a certain perceptual and rational understanding of electrical components and circuit connection and debugging, laying a good foundation for learning electrical technology classes in the future.
4, familiar with the categories, models, specifications, performance and scope of use of commonly used electronic devices, can consult the relevant electronic device books. 4) Be able to identify correctlyAnd use commonly used electronic devices, and be skilled in the use of ordinary multimeters and digital multimeters. 5) Learn to read circuit diagrams, familiar with the identification of electronic components symbols, master the welding of electronic products and circuit debugging. 6) Understand the structure and working principle of some common electronic products.
1, electrical and electronic skills competition has these competition items: electronic product assembly and debugging, mechatronics equipment assembly and debugging, MCU control device installation and debugging, refrigeration and air conditioningEquipment assembly and commissioning, electrical installation and maintenance of five projects.
2, competition projects: including electronic product assembly and debugging, mechatronics equipment assembly and debugging, SCM control device installation and debugging, refrigeration and air conditioning equipment assembly and debugging, electrical installation and maintenance of five projects. Among them, wireless charging flux , mechatronics equipment assembly and debugging are divided into secondary vocational students group and higher vocational students group, electrical installation and maintenance are divided into secondary vocational students group, higher vocational students group and teacher group, all of which are group projects; The remaining events are individual competitions.
3, electrical and electronic technical skills competition Wireless charging flux The name of the 2009 National Vocational College skills Competition in the vocational group electrical and electronic technical skills competition. The competition projects include electronic product assembly and commissioning, mechatronics equipment assembly and commissioning, SCM control device installation and commissioning and refrigeration and air conditioning equipment assembly and commissioning. Each event has different requirements and restrictions for competitors.
Common tools include: hardwareTools, welding tools and common special equipment, etc. Hardware tools mainly refer to the use of mechanical principles to install and process electronic products. Generally divided into ordinary tools and special tools two categories. Common tools commonly used are: screw screwdriver (also known as screwdriver, commonly known as screwdriver or driver); Needle nose pliers; Diagonal pliers; Wire cutters; Scissors; Tweezers; A wrench; A hammer; A file.
oscilloscope, if you often repair the radio and other pure analog circuit things, you can buy this device, but it is more expensive, do not buy it. I don't. Screwdriver set, essential. 1 Tweezers, straight and curvedIt is best to have both, and it is more convenient when welding and removing components. 1 If you repair mobile phone chargers, computer host ATX power supply and other switching power supply equipment, it is recommended that you make your own safety light device.
Commonly used electrical tools are electric pens, insulation tape, insulation rubber shoes, insulation gloves, anti-static clothing, screwdriver (screwdriver), offset pliers, needle-nose pliers, fine electronic products also need electronic multimeters. Basic personal tools: electric pen, electrician's open pliers, gong knife, electrician's knife, open wrench, etc.
Electric soldering iron is a necessary tool for electronic production and electrical maintenance, and its main use is welding machine components and guidesLine, according to the structure can be divided into internal heat type soldering iron and external heat type soldering iron, according to the function can be divided into welding electric iron and tin absorption electric iron, according to the use of different is divided into high-power electric iron and low-power electric iron. Internally heated soldering irons are smaller and cheaper. General electronic production uses 20W-30W internal heat type soldering iron.
Multimeter (pointer, digital), oscilloscope, frequency meter, signal generator, service power supply, constant temperature soldering iron, hot air welding table (heat gun) soldering gun, soldering wire, if you have money to get a BGA welding table, welding BGA components. That's all there is. That's all there isMaintenance of major tools.
