Nano Coulomb Meter
NANO COULOMB METER is a pencil-type digital charge measuring instrument
with which the excess dynamic charge on a semiconductor device,
a leading cause of its static breakdown in the fabrication, inspection,
assembly, and other processes, can be easily measured simply by
applying the instrument's probe to its lead.
CHARGE MEASURING INSTRUMENT MODEL KQ-701/KQ-801
dynamic charge (Q) can be determined from equation Q=CV by storing
it in a capacitor (C) and measuring the voltage (V) between its
terminals. The NANO COULOMB METER is a new type of charge measuring
instrument designed to measure excess dynamic charge with its pencil-type
probe in contact with the object of measurement.
Employs a probe
measurement system which allows excess dynamic charge to be easily
measured simply by bringing the probe into contact with the object
The measured excess dynamic charge can be held or canceled at the
mere touch of an electronic switch.
The probe tip of the pencil-type probe is a replaceable unit. The
optimum type of probe tip can be selected according to the application.
The probe tip is of a spring type which enables measurements to
be performed without damaging the object of measurement.
Compact, lightweight, and easy to operate, this instrument can be
conveniently used in the field of production.
