Cleaning Stations

In South Africa there is a lot of dust involved in factory enviroment. When we receive units for the repair we see often devices covered with thick layer of dust.  Dust is not harmful for the devices if its conductivity is low but if dust has conductivity in nature, it will cause shorts in the devices. In force ventilated devices, cooling blower bearings are first to fail. The blocked heat sinks are increasing the devices internal temperature and causing over temperature failures.

In the beginning of our repair process we start from the unit cleaning. Our cleaning has two stages, first the dust removal in controlled vacuum cabinet and second the ultra sonic washing with liquid solution. In case of the devices with lacker layered PCB boards, we may need to remove lacker before starting circuitry level analysis and repair.
