Piezo exchange

A piezo element exchange requires a total disassembly of the digital back. The two piezo elements are replaced in the aluminium frame. 

Before assembly of the digital back, additional hardware modifications are conducted if necessary to ensure the best possible performance for the specific product. 

After a piezo element calibration and a CCD-sensor calibration, the CCD and the IR-filter is cleaned, and the filter is re-mounted (or replaced if it has any scratches).

For further details, please refer to the descriptions of “piezo calibration” and “CCD cleaning”. 

After passing all tests, the back is ready to leave the workshop again.
