PTC Phone Acc And Repairs was founded in 10 years ago, After a period of rapid development, it has developed into a considerable size and effectiveness company of i battery repairandToowoomba repairx1d16936n, NOw it is benchmark companies in Industry and agriculture,Business services industry.
PTC Phone Acc And Repairs is specialized in Business services,Domestic services,Digital / mobile repair since established in 10 years ago.So far,our company has established its branch companies in major cities throughout the country.Formed in 4 ironstone road, berrinba, QLD 4117 as the center, the radiation sales system and service network.Details:
Apply the trick: if we are surprised to find that the fails after using the wind gun to weld IC or blow dry with a hair dryer.However, after the has cooled down for a period of time, the failure will occur again, and the failure will disappear again after heating, so that we can use this method to find the tiny points of failure.This method is very good, you might as well try!Specific instructions: heating the local device with a soldering iron, if heating the CPU, the cell can signal, the failure may be on the CPU, we can try to change the CPU;If the heating medium frequency IC or audio IC malfunction may be in the audio or medium frequency IC;Heating 13MHz master clock clock crystal, there is a signal that the fault of the may be that the clock crystal is not able to vibrate.In particular, many mobile s have no signal that the frequency of 13MHz occurs when there is no signal. We can use heat to determine whether the 's signal is caused by the 13MHz master clock.In addition, this method is also effective for audio IC and intermediate frequency IC failures.On the surface of the actual maintenance, the method of local heating can identify fault parts, and the method of heating the whole machine can blur the faults of some s. the theory basis of local heating: now let's analyze the reasons for this phenomenon: the integrated IC inside, all is by the crystal semiconductor into enough, crystal semiconductor and stable work, must have a stable temperature and humidity.If the mobile be affected with damp be affected with damp or continuous work under harsh environment, by the nature of the semiconductor, mobile can't work normally under normal circumstances, that is, its electrical parameters change.So any of our electrical equipment has electrical work parameters.It's not easy to change.And even more requirements to the crystal clock has the right temperature, once the temperature too high or too low, could cause major mobile clock crystal oscillation frequency offset or completely unable to start up, so they have "the temperature compensated crystal".Our method of maintenance is mainly to change the electrical characteristics of the mobile - that is, it must have a higher temperature to work properly>
With the purpose of "Quality first, service is paramount" in ptc, our strict product quality control system ensures that Toowoombat i repair, repair brisbane and other products of high quality and stability. We have a first-class laboratory equipment and a highly experienced profess
