In commercial FLASH memory chips, it is recommended to update the information by rewriting the memory dump every 5…10 years.

Since nothing is perfect in the world, and over time, the charge on the gates of transistors decreases, which can result in data loss and failure of the device that depends on the operation of FLASH memory. It is on this principle that the main types of NAND and NOR flash memory are developed.

The peculiarity of such a transistor is that it can hold electrons (charge). The unit cell of data storage in FLASH memory is a floating gate transistor. Next, we will explain in detail why it is necessary to update the FLASH memory at least once every 5…10 years. Some people ask: «Why update all the modules and spend an extra 2 hours on it?». For example, CCC includes 5 modules, the total update time, which takes about 2 hours, but you do not have to leave the car or wait 2 hours, since we do the whole process without the participation of a car. The whole process is done on a test bench, so you don’t have to connect a diagnostic computer to your car at all. Update all modules of the multimedia device.Īt the end of the repair of the device, we perform the correct update and coding for it in accordance with the VIN and taking into account all changes in the factory configuration after retrofitting or re-equipping with various options. Prevention, as a rule, takes longer than the repair itself, but thanks to this, you get a device that is much more reliable than, for example, buying a used device, which on average gives a guarantee of 1-2 weeks (our guarantee is 56 weeks). In addition to repair, we do preventive maintenance or replacement of electronic components, which most often can lead to failures in the operation of a multimedia device in the future. Prevention of elements that are most often the cause of a malfunction. Thanks to all this, we can provide you with a high warranty period. At the end of the repair, we test multimedia devices at the stand for several hours. Components are mounted using high quality solder and flux. For soldering microchips, we use specialized equipment that allows you to strictly observe the temperature profile in order to ensure the longest possible life of chips after exposure to temperature.

We have many years of experience in the repair and design of complex electronic devices.
