Regarding measurement of electric contact

Difference in probe tip shape

C Type

Tip Type:C Plating Material on DUT:solder

Crown 4-point

solder Plating

C Type 半田

【See also:Dispersion Data(Before-calculating-average】

C Type 半田

※＜DUT＞Shape : Round/Flat (diameter:Φ16mm　height:3mm)

※＜Probe＞Type : CP20　Tip Material : Carbon tool steel (Aurum plating)

※＜Ohm Meter＞HIOKI 3560 AC mΩ HITESTER (1mA)

＜NOTE＞Data can be different by the degree of surface oxidization or of the thickness of the surface plate.
Where the contact areas of DUT and probes are flat, roughness or plating conditions of each surface can easily affect data.
