Automated Lock-In measurement with E-LIT from InfraTec
E-LIT – Lock-In Thermography for electronics is an automated testing solution system (as part of NDT techniques) which allows non-contact electrical failure analysis as well as checking the authenticity of semiconductor material, electronic components, and electronic circuits. Inhomogeneous temperature distribution, local power loss, leakage currents, resistive vias, cold joints, latch-up effects and soldering issues can be measured with Lock-in Thermography. This is achieved by using the shortest measurement times combined with a high-performance thermographic camera and a specialised lock-in procedure.
The electrical excitation for the semiconductor test gets its parameters from the system and is clocked with a synchronization module. Even failures that produce mK or even μK temperature differences are reliably detected by the Lock-in Thermography system.
Smallest defects at electronic components like point and line shunts, issues from overheating, internal (ohmic) shorts, oxide defects, transistor and diode failures on a PCB surface, in integrated circuits (IC´s), LED modules and battery cells can be detected and displayed in x and y positions. Additionally, it is possible to analyse stacked-die packages or multi-chip modules in z-direction with merely changing the lock-in frequency. In conjunction with algorithm-based pattern recognition, manipulation of the circuits can also be detected. For these and similar tasks the powerful lock-in thermography software uses the latest algorithms and routines from most recent scientific publications.
E-LIT is extremely powerful also in resolving the smallest geometrical structures as it can be equipped with strong microscopic lenses and additional SIL lenses. With the help of thermal cameras with detector sizes of up to (2,560 x 2,048) pixels, even micro defects can be recognised and analysed.
