Before repairing an electronic device, you first need to find the faulty component on its printed circuit board, or PCB. this can be a challenging task, as different components require different test procedures.

Passive components such as resistors and inductors fail less frequently, although they too can be damaged or burned out.

A digital microscope is applicable to the inspection of electronic industry production line, the inspection of the printed circuit board, the inspection of welding defects (printing misalignment, collapsed edge, etc.) in printed circuit assembly, the inspection of single-board PC, the inspection of vacuum fluorescent display VFD, and also the identification of printing grid, word painting, etc.
