of inspection systems using the classic
pulse method (simple sound testing). In
addition, the conventional inspection
methods employed by most industrial
companies cannot evaluate from what
point onwards a measurable defect is
function­relevant. Many critical process­relevant
factors remain untested.
PCRT compensates for process variations
that could falsify the results within
a defect search. There is a function­relevant
inspection and the extent of the
damage is quantitatively assessed. In
this way, producers can achieve a major
improvement towards the 0 ppm defect
demand for safety­relevant failure­critical
components. And considerably reduce
cost­intensive pseudo­rejects.
