Ceramic Chip Capacitors
Introduction
RGA Multilayer Ceramic Capacitors are constructed by screen printing alternative layers of internal metallic
electrodes onto ceramic dielectric materials and firing into a concrete monolithic body. Secondly, they are applied
with metal end terminations which are fired to assure permanent bonding with the individual internal electrodes.
Reliable performance is built-in through fine formulation of dielectric materials, preparation of conductive pastes,
automatic manufacturing and strict process control. This assures excellent control in dielectric thickness, electrode
integrity, electrode to termination continuity, termination to lead connection and coating insulation.
Dielectric formulations are identified and classified by the capacitance temperature coefficient of materials.
NPO, X7R, Z5U and Y5V are the four most common for industrial use. The internal electrodes and end
termination pastes are made of extremely precious metals; such as palladium, and silver, which result in a lower
dissipation factor. The inherent high resistivity of ceramic dielectrics yields very high values of insulation resis-
tance. A safety factor is also added up in thickness design to withstand undesired transient voltage surges. The
final construction has excellent frequency characteristics.
Since the soldering period of the SMT process takes a much longer time than the conventional assembly
process, a special treatment of MLC chip end termination is required to prevent silver electrode from leaching
during soldering. Nickel barrier is electroplated on the top of the silver layer which is suitable for this purpose,
along with a solder layer which is electroplated consequently to enhance the solderability.
This type of capacitor is especially produced for SMT or hybrid assembly, which use reflow, vapor phase, wave
or any other kind of soldering systems.
