PM-700 SERIES PLATING MONITOR

1. GENERAL DESCRIPTION
The PM-700 Series of Plating Monitors act like intelligent electronic coupon
systems. The monitor continuously displays the thickness of the film on the
coupon and the rate of change of that thickness. It does this rapidly, in fractions
of a second, and with very high resolution.
The heart of the intelligent coupon is the quartz crystal mounted in the end of the
probe. It is the film on this crystal whose thickness and rate of change of
thickness is displayed on the monitor.
Use of this technique allows instantaneous measurement and display of the plating
rate of any liquid plating or etching process.
The basic monitoring system consists of the monitor itself, a probe with the
crystal installed and a cable connecting the probe to the monitor.
Various configurations of monitor, probe and crystal are available to meet
different requirements and the monitors incorporate numerous user modifiable
parameters so that they can be tailored to specific processes.
