CATHODIC TERMINAL
The negatively charged (-) terminal to which racks or barrel loads are
attached in the plating tank;
( also called 'CATHODE' ).
CATHODE
The negative electrode in electrolysis in which the parts are plated. The electrode at
which positive ions are discharged. In plating, the parts themselves are cathodes.
CATHODIC CLEANING
Electrocleaning the part with negative voltage. It is also called direct cleaning.
Hydrogen is generated and can cause hydrogen embrittlement.
CAVITATION
Cavitation is the cleaning action of collapsing bubbles on the surface of a part
when using ultrasonic energy.

CENTRAL TENDENCY
There are three measures of central tendency: 1.) AVERAGE (
mean ) - the sum of all the measured,
or counted data, divided by the total number of data points.
2.) MODE - the value repeated most
often in raw data, or in the case of the HISTOGRAM, the most common class
interval.
3.) MEDIAN - the middle of all the measured or counted data points (
if an even number of data
points, the median will be a fraction ).

COMMON CAUSE
The source of random or natural variation in a process.
Common causes-or
'assignable causes ' as they are sometimes called-are inherent
in the production process itself.
CONC
CONCENTRATION
CONFIDENCE LEVEL
The probability that a given range of values contains the true value of a parameter.
CONFIDENCE LIMITS
The upper and lower boundaries of the confidence interval.
CONSUMER’S RISK
For acceptance sampling the probability that a bad lot will be accepted by a given sample
plan.
CONTROL
A term applied to the management of processes indicating that quality
requirements
standards or goals are being met and that the output of the
process is predictable.
CONSTANTAN ALLOY
This alloy contains 45% nickel and 54% copper, used in thermocouples.
CONTACT PLATING
The deposition of metal without the use of current. The parts are barrel-rotated in a bath
containing metal ions. As the parts come in contact/impact with the metal ions, they get
plated.
CONTROL CHARTS
Control Charts are line graphs specially used to track the trend or
performance of an on-going process.
This is accomplished by observing how the viability within the
process causes thetrend line to fluctuate
within a pair of statistically calculated limits. There are two
types of Control Charts: _ X, R CHART
and X, MOVING RANGE CHART which are VARIABLES CONTROL
CHARTS. p CHART, np CHART,
c CHART, and u CHART which are ATTRIBUTE CONTROLS CHART.
CONTROL LIMITS
Control limits, which are statistically derived, are not to be confused
with specification limits.
Ideally, control limits are well within the specifications so there
is confidence in the reliability
of the process. If the specifications are very close to or
within the control limits, then the process
is indicating that it may not be reliable in achieving the customers'
needs.
COR
CORROSIVE EFFECTS
CORROSION
Corrosion is a chemical process by which a metal is chemically oxidized and
attacked.
COST ESTIMATION
Cost Estimation is a technique for determining the dollar or currency
impact of problems and potential
improvements. There are two approaches to estimating costs: The
'Bottom Up Approach' and the
'Top-Down Approach.' It is not necessary to have a precise and
detailed accounting data in order to
get a general idea of the financial impact of a problem or
issue; you need to make some assumptions
and verify them as data is collected.
COULOMB
A electrical charge passing through or plating cell at a current of one ampere for one
second.
COULOMETRIC CELL
An electrolytic standard cell arranged in series with a plating cell to measure the actual
current flow. From the weight of
the deposits in both cells, the cathode efficiency can be calculated.
COVERING POWER
The ability of plating solution to deposit on very low current density areas. A high
throwing power bath ususally
has high covering power.

CUM
CUMULATIVE EFFECTS
CURRENT DENSITY
The plating current per unit area being plated. The current density is expressed as ampere
per square foot or ampere per square decimeter.
CURRENT EFFICIENCY
The percentage of current actually used in deposition at the cathode or in dissolving the
anode. The remaining current generates either hydrogen at the cathode, oxygen at the anode
or other side reactions at either electrode.

CWQC
COMPANYWIDE QUALITY CONTROL is an expression used widely in Japan,
CWQC means the application of quality principles to all processes in a
company
and the involvement of all employees at all levels in the
quality-improvement process.
The concepts of continuos improvement and customer satisfaction are
also embedded
in the approach. CWQC is the equivalent of 'total
quality management ( TQM )' in the
United States, where the term 'management' has the same meaning as
'control' in Japan.

CYCLE TIME
The amount of time it takes to complete a particular task.
Shortening the cycle
times of critical functions within a company is usually a source of
competitive
advantage and a key quality-improvement objective.
