The use of a spreadsheet-based computer program to assist with control
of plating baths is described, This program saves time by automating
record-keeping, calculations, and graphing, The program calculates add
s based On the chemical analyses. and provides adds for each Shift unt
il the next analysis Is due, In addition to an immediate response to t
he analysis, the program examines the recent concentrations and compar
es them to the control limits. The estimated amount of chemical used p
er shift is adjusted in response, and this is used in future calculati
ons, which helps prevent a recurrence of any excursion, The control of
our tanks has improved as a result of the time saved and the consiste
ncy of the computer's response.
