Description:
A dielectric material is a substance that is a poor conductor of
electricity, and used as an insulating layer in the PCB build up.
Porcelain, mica, glass, plastics and some metal oxides are good
dielectrics. The lower the dielectric loss, (the proportion of
energy lost as heat) the more effective the dielectric material. If
the voltage across a dielectric material becomes too great -- that
is, if the electrostatic field becomes too intense -- the material
will suddenly begin to conduct current. This phenomenon is called
dielectric breakdown.
Our high density circuit boards have the technology pushing capabilities to drive applications in a
large number of industries including but not limited to semiconductor test equipment, defense,
medical and aerospace.
