Glossary of Terms for all Engineers, manufacturing, and others in the Electronics market, the terms are most on Electrical Testing and process of chip capacitors, multilayer ceramic capacitors, single layer ceramic capacitors and process of ceramic dielectric materials.
The loss of dielectric constant (see dielectric constant), by dielectric relaxation, expressed
as % per decade of time.
Process of exposing the capacitors or any other device to elevated temperatures with voltage the purpose is to screening out marginal parts, eliminating potential field failures.
A device consisting of alternate layers of conductor and insulation materials (ceramics....),
capable of storing a charge of electricity.
The quantity of energy stored by a capacitor (expressed in farads).
Apply heat to the ceramic powder to a temperature below the sintering temperature in
order to pre react certain ingredients.
To pour a smooth film of ceramic slurry to produce ceramic tape.
A sintered Monolithic, Single layer, multilayer ceramic capacitor and noble metal.
A material capable of carrying (conducting) electricity. Silver is the best electrical conductor.
Copper, gold, and aluminum are also popular conductors.
In barium titanate dielectric, that temperature where the crystalline changing from cubic
to tetragonal form, and the material becomes ferroelectrics from Para electric. and at this
point the dielectric constant is max.
A chemical added to a ceramic formulation to lower the dielectric constant at the curie point.
Separation of layers of a sintered capacitor, resulting from air inclusion during lamination,
or during fast burnout of the Binders.
Dicing / cutting
Separate the lamination of ceramic into smaller pieces by blade, diamond wheel, or any
other cutting means.
in chips capacitors, it is the ceramic insulator that capable of high degree of polarization.
A non-conductor of current, an insulator.
the ratio between the absolute permittivity of a material and the absolute permittivity of vacuum.
The ratio of recovery voltage after discharging of a capacitor to the charging voltage.
Expression in %, caused by the accumulation of remnant electrons on the electrodes.
The power lost in a capacitor as measured by comparing the difference between power
input and power output, also called tan delta or Dissipation factor (DF).
Used between metal layers and dielectric layers in order to prevent diffusion of atoms
into underlying layers.
The rate at which a diffusing will diffuse into bulk material at a given temperature;
measured in cm2/sec.
Conductive noble metal film.
A process for depositing metal films on a capacitor by dipping the capacitors in an
electrolytic solution and permitting a current to flow through the liquid.
Electrostatic discharge - ESD
Transfer of charge between bodies at different electrical potentials.
Removing unwanted materials from the surface by chemical milling or electrolytic process
A crystalline material that exhibits spontaneous dielectric polarization, hysteresis,
and piezoelectric properties.
Ceramic tape that has been cast and dried.
Powder glass, used in metal inks to bond the metal particles to a substrate when heated
to the melting point of the glass.
Ceramic laminate or tape before firing (sintered)
An atom that has either gained or lost electrons making it a charged particle
(either negative or positive, respectively).
ltcc - Low Temperature Cofired Ceramic.
Metallization / Termination
