PM-700 SERIES PLATING MONITOR

3.1 SAMPLE PROCESS

Suppose a PM-700 monitor is to be used to continuously measure the plating rate

and thickness in an electroless nickel bath, giving a deposit with 6%

phosphorus. Since this bath will not initiate plating on a pure gold surface, the

sensor crystal will have to be electrolytically preplated with, for example, .5

microns of nickel at a controlled rate in order to support subsequent autocatalytic

electroless plating. Assume that the desired plating thickness endpoint is 20

microns and it is desired that the plating monitor warns the operator if the plating

rate falls outside the normal limits of .100 ±0.02 micron/min. It is also desired

that the total elapsed time since introduction of the work into the plating bath be

displayed. These parameters will be established for process number 3.

Given the above example, the following list of parameters will need to be

programmed into the monitor.

Table 2 Sample Process Parameter Values

Menu Parameter Value

Process Menu Process Number 3

Process Menu Endpoint Setting 20.00

Process Menu Min Rate Alarm 0.080

Process Menu Max Rate Alarm 0.120

Mode Menu Sample Off

Bath Menu Bath Ni 6%P

Bath Menu Type Elecless

Bath Menu Preplate Thckness 0.500

Bath Menu Preplate Rate 0.050

Display Menu Parm Status Display Elaptime

Setup Menu Simulate Off

Since the above parameters will be established for process number 3, the first

thing to do is select process number 3 as the current process. You can do this by

going to the Process parameter in the Process Menu and use the SELECT arrow

buttons to find Number 3. Then follow the above list to program the rest of the

parameters.
