The parts and components of cell phone jammer

Maintain the cleaning of the circuit board is not operating, to prevent all of the solder, tin beads, wire material, conduction material off the people board, to avoid other aspects of the failure. Different manufacturers, different models, different styles, its version number, use the same version of a qualified normal chips, components, avoiding the replacement of different versions of the chip. To refrain from the use of substandard, piracy, smuggling chip components, so as to avoid the more complex failure. In this, the correct analysis of the circuit, correct an error of judgment. The right to find fault position is very important to avoid false positives. Pay attention to check the phone's menu settings are correct, the failure of many mobile phone menu is not set in the correct state. Normally, the technical group of  cell phone jammer will hold a meeting.
The repair is completed, the cleaning, sorting table is necessary. Maintenance tool for homing, re-fitted with all the attachments (long screw, antenna sets, rubber, insulator, etc.) to prevent the repair time less things. Maintenance staff to master the basic terminology and basic knowledge of mobile phone repair in order to determine the failure to produce the original back and the approximate range, to avoid one by one according to its principles of testing, or to find the point of failure in the entire circuit board. Troubleshooting steps. As a doctor to "look, smell, and asked", diagnosed the condition and the right medicine. Repair mobile phone failure, is also subject to ask, see, hear, touch, thought to repair the six stages. Only for the different models, different fault, use a different method of repair. These are parts and components of cell phone jammer .
As doctor visits, the first like users to understand some basic information. Such as the cause of the failure process and the reasons for the phone's useful life, and Condition of the situation. This inquiry should be further observation to pay attention and be thinking clues. A wide range of mobile phones, will inevitably encounter the previous exposure to a few new models or models of the market less, to see when combined with specific models. Mobile phone repair, look at the machine when the green LED status indicators blink when the call to allocate and display information. The combination of these observed phenomena to provide ideas for further diagnosis of failure. Preliminary judgment failure awaiting repair mobile phone voice quality, volume status, the sound is intermittent and other phenomenon. Normally, the high power  cell phone jammer  is not suitable for the shielding school.
For power amplifiers, transistors, integrated circuits and certain components. Touch can touch the level of surface temperature, such as hot, think of whether the current is too large or heavy load can be based on the experience of rough to determine the fault position. Namely analytical thinking. Previously observed, all the information collected, the use of maintenance experience, combined with a specific principle of the circuit, the use of necessary means of detection, carried out the analysis, thinking, judgment, and finally made the overhaul program. Has failed component replacement, welding. Discarded after the technical processing and then use the parts as far as possible to save costs. A unit of low power  phone jammer is enough for the shielding of a classroom.
