Z-Check
500
Z-Check 500 is the low cost entry
level, non-contact thickness measuring instrument for the
fast and accurate measurement of Solder Paste, Adhesives
(Glue), Components and Leads. The high precision measuring
mechanism, with a measuring range of 10mm, is securing
mounted on a robust, large granite base, making Z-Check 500
ideally suitable in any production or laboratory
environment.
Z-Check 500 works by differentially
focusing between the sample substrate and the top of the
sample being measured, ie solder pad. Operator error is
removed by a unique optical sighting system. A micro-slit of
white light is projected onto the sample surface from an
acute angle. When this is coincident with a central
graticule on the monitor, the subject is in focus. When the
sample is moved, the light slit also moves laterally and
bringing this back to coincide with the graticule, refocuses
the instrument.
The distance moved by the
microscope in refocusing, is the difference in height
between the first and second position, and is displayed on
the instrument. In this way varying interpretations by
different operators on the focus position is eliminated.
Typical accuracy is 3 micron. Both the micro slit of light
and surface illumination can be individually adjusted to
suit any surface condition.
