Case study

Unstable data

⇒A problem caused by an improper wiring method.
See what is the suitable method for each measurement.

⇒A problem derived from the probe structure.See what is different in contact resistance between outer-spring type and inner-spring type.

⇒A problem derived from the improper tip shape for the DUT.
See an example of selecting the suitable probe considering conditions of DUT.

Plating material being fused

⇒A problem in a measurement under high current.
It results from high contact resistance generating heat at the contact point.

Spark occurring and melting contact area

⇒A problem in a measurement under high current.
It results from deformation of the probe tip.

Spring broke

⇒A problem caused by an improper wiring method.
See how the current flows differently through the probe by different wiring methods.

Spring performance getting stiff

⇒A problem derived from metal powder deposit.
It is produced by the longer spring stroke than recommended.

Problem solutions are variable depending on measurement circumstance.
 Please note that, even if apparently similar problems occur, the following solutions stated here will not be always effective to every problem.
