Counterfeit ICs have become a problem in the modern market. All sorts of companies that handle IC devices are affected by this trend:
- OCM have to handle fallout from devices people think are theirs but are not.
- OEMs need to screen parts and eliminate them from stock so they do not use them and compromise the reliability of their products.
- IC Distributors need to ensure that the parts they sell to their customers are good quality and not counterfeit. They have a legal and economic reason to supply good parts.
Curve Tracers are highly flexible for IC characterization
. Often designed specifically for the task of characterizing loose IC devices, they offer the best balance between precision and flexibility.
- They feature configurable multi channel switch matrixes which allow for a wide variety of test conditions to provide flexibility for a wider range of devices
- They have multiple SMU (Source Measure Units) so that in addition to obtaining an I-V signature, they can provide multiple other bias voltage or current to devices allowing for testing in the powered up state
- The measurements that are obtained are generally high precision and allow for screening devices to a much tighter tolerance, accuracy and repeatability.
- Since they are designed for this task, the software is much better optimized for configuring all these various test conditions and analyzing the piles of data that can be produced
