What sample preparation is required before using the CS1000?
In general, powering the sample is the only sample preparation required. The CS1000 measures magnetic fields, which are only affected by ferromagnetic materials (Fe, Co, Ni, and certain of their alloys). Because almost all ICs and packages are non-magnetic, these magnetic fields are unaffected by any encapsulation or even intervening metal layers. Therefore, the CS1000 can “see” all the magnetic fields from the device without the need to de-layer, polish, or otherwise process the sample.
