PLATING KATE AND THICKNESS MONITORS MODULAR MULTIMETHOD THICKNESS GAUGE Maxtek Inc., Torrance, Calif: Fischer Technology, Windsor, Conn.
MAXTEK Inc. manufactures a line of real-time, online plating rate and thickness monitors appli- cable to both electroless and electrolytic processes. These instruments utilize Quartz Crystal Mi- crobalance technology to implement a Smart Cou- pon Probe, which when inserted in the bath pro- vides continuous and instantaneous digital readout of plating rate and thickness.
The Fischerscope MMS is a modular coating thickness measuring instrument that allows the user to combine and configure different test meth- ods to suit a wide variety of coating thickness measurement applications. With a single base unit and multiple Fischer Smart Probes, the user can perform measurements using the magnetic induction, eddy current, beta backscatter, electri- cal resistance, or a combination of these test meth- ods. Fischer also offers a unique, new dual probe that combines the eddy current and magnetic in- duction methods in one probe.

THICKNESS TESTING SYSTEM Kocour Co., Chicago
The Kocour Co. has introduced the Model 6000 thickness testing system, which uses the coulomet- ric principle. A small controlled test area is anodi- tally deplated in an electrolytic cell at a constant current. Thickness is determined by the current and time required to remove the plating. When the sub- strate is exposed, the 6000 turns off automatically and displays the thickness on the instrument panel. The Model 6000 thickness tester measures almost all electrodeposited metals on metallic or nonmetal- lic substrates. It can measure multiple coatings and give individual readings. It measures plating thick- ness on wire and very thin coatings, such as decora- tive chromium and gold, then displays the readings to the millionths of an inch. The Model 6000 is also capable of measuring the electrochemical potential difference between duplex and triplex nickel layers (STEP) and also measures electroless nickel.
