Relative Permittivity
The relative permittivity or dielectric constant indicates the force between two charges of a certain distance at free space and any other medium. It impacts the signal integrity and impedance control of dielectric materials.
Its lower value is good for high-frequency LED bulb PCB applications. Usually, LED circuit board materials have relative permittivity of 3.5-5.5.
Loss Tangent
The loss tangent or dissipation factor indicates the deficiency of power in a PCB operation. If you find a low loss tangent, it means the device will lose less power. LED driver PCB materials offer a loss tangent between 0.001 and 0.02.
Electrical Strength
It refers to the electrical potential that is required to break the insulation of PCB materials. Normally, electrical strength is measured in the Z-axis.
Volume Resistivity
This is the capability of LED components to resist electricity or insulation.
Surface Resistivity
It indicates the surface resistance of dielectric substances against insulating properties or excessive current flow.
