本人毕业后由于对无线移动通信的喜爱,通过培训掌握了手机等移动通信工具的基本构成、工作原理、故障产生原因和处理办法,通过一段时间的社会实践对一些市场主流机型所产生的故障问题有了一定的认识和处理办法,我在哈尔滨长城通信公司做售后服务工作,主要负责一般故障的检测和处理,在维修过程中主要面对的问题是:不开机、进水、由于外力对机器的损害和一些软硬件方面的问题,如在开不了机的情况下,首先判断是否电池触方虚接,电源三极管是否击穿可利用可调电源夹方接触主板触片正负极,无反应则为电源问题或三极管击穿,有反应但电源指针回打应为主板漏电或集成IC块有虚接断路现象,通过 方框图找到集成块负责电源的一脚,使用低压烙铁拿下电源三极管或用风枪对集成块进行有目的的热扫或通过显微镜找到虚接点加以处理,对于机器进水应在最短时间拿下电池,利用处理液冲洗,对于自动关机性况应该考虑电池触片和软连带是否老化,对于常见的LCD显示屏无显示或缺字应用压屏烙铁对屏幕与主板接触点进行处理或更换屏幕连带甚至主屏幕,对于手机通话掉线,网络差等故障,通过检测本振电路利用频谱仪对集成块附近电阻进行检测,阻值不符及时更换,对于CPU、内存、码片等软硬件问题,如出现乱码等现象,可通过电脑软件对CPU、码片等程序重新编写,其它问题要在工作中具体情况具体分析。

After I graduated from the love of wireless mobile communication, through a mobile phone with training tools such as mobile communications basic composition, operating principles, and the reasons for the failure of the approach, through a period of social practice of some market failure arising from the mainstream models have a certain understanding of issues and approaches I Harbin Great Wall communications companies doing after-sale, primarily responsible for the general failure of detection and treatment, in the course of major maintenance problem is : do not switch on the machine, get flooded, due to machinery outside force damage and some software and hardware aspects, such as the fact that the plane of the first judge whether any side empty cells Next, Puncture power triode is the use of maximum power between parties may contact the Main Board with films being cathode, the reaction was no power or triode puncture, but a reaction to fight for power for the Main Board leakage or integrated IC blocks to open circuit phenomena are empty, find Jichengkuai through block diagram for the kick power, Use low voltage soldering iron down wind power triode or use a gun for the purpose of Jichengkuai heat up or through microscopes to find a way to deal with connections to machines get flooded batteries should be taken in the shortest possible time, the use of liquid water processing, automatic machines for sexual battery status should consider whether it is associated with aging film and soft, For common LCD monitors showed no missing words or pressure applied to the screen soldering iron screen with the Main Board point of contact for dealing with the replacement of screens or even the associated screen for the phone calls Diaoxian, poor network fault detection through the use of the spectrum -- circuit-to Jichengkuai near resistance testing, resistance value with the timely replacement of the CPU, memory, films such as software code, such as a mis-coding and other phenomena through computer software to the CPU, code rewriting procedures films, the work of other issues in a case by case analysis.

After myself graduate because to the wireless mobile communication affection, grasped mobile communication tool the and so on the handset through training basic constitution, the principle of work, the breakdown has had the reason and the processing means, the breakdown question which produced to some market mainstream types had the certain understanding and the processing means through period of time social practices, I did the post-sale service work in the Harbin Great Wall correspondence company, the primary cognizance general breakdown examination and processing, the question which mainly faced in the service process is: Opening machine, does not enter the water, as a result of the external force to the machine harm and some software and hardware aspects questions, if in cannot open machine in the situation, first judges whether the battery does touch Fang Xujie, whether the power source triode does penetrate may use may adjust the power source to clamp the side contact motherboard to touch the piece cathode, does not have the response penetrates for the power source question or the triode, has the response but the power source indicator to return hits should or integrates the IC block for the motherboard leakage to have empty meets shuts the phenomenon, found the integrated block through the block diagram to be responsible for the power source a foot, The use low pressure iron takes the power source triode either carries on with the air gun to the integrated block has the goal the heat to sweep or found the empty contact through the microscope to perform to process, enters the water regarding the machine to be supposed to take the battery in the shortest time, the use processing fluid flushing, regarding automatic Guan Jixing the situation should consider the battery touches the piece and the soft association whether do get older, does not have the demonstration regarding the common LCD display monitor either lacks the character application to press the screen iron carries on processing or the replacement screen association to the screen and the motherboard contact point even advocates the screen, falls the line regarding the handset telephone conversation, the network inferior breakdown, inspires the electric circuit through the examination book to integrate nearby the block using the spectrometer the resistance to carry on the examination, The resistance number symbol prompt replacement, regarding software and hardware question and so on the CPU, memory, code piece, like does not appear phenomenon and so on additive device, passable computer software to procedure and so on CPU, code piece rehas compiled, other questions must in the work the special details concrete analysis.
