    COB technology supports using more diodes (almost 9 or more) along with LEDs. But SMD LED circuit boards don’t consist of more than 2-3 diodes. Sapphire wafer is the main raw material of LED.

    Colour Changing Facility

    SMD LEDs offer multiple alterations in their designs. That’s why they can provide color-changing facilities in PCB applications.

    On the other hand, COB LED consists of a circuit and two contacts which are not enough to create a changeable feature.

    Lumen Count

    COB LEDs contain cooling ceramic that helps improve lumen count per watt. Besides, they can ensure thermal efficiency more conveniently than SMD LEDs.

    What Are The Different Layers Of A Multilayer LED PCB?

    A multilayer LED PCB design consists of different layers which have particular functions. Here, a list of layers is given for your convenience.

    Routing Layer

    This layer remains in the inner and outer portions of an LED bulb PCB. Usually, routing layers form a zone where LED components interconnect.

    Mechanical Layer

    A mechanical layer creates the outline of the LED printed circuit board configuration. You can find this layer in rectangular, cornered, etc shapes.

    Power And ground Planes

    This multifunctional layer distributes power and ground through various LED components. These layers remain in the top, bottom, or middle of the PCB designs.


    Its other name is the silkscreen layer. This layer contains texts on the upper and lower sections of PCB. You can avoid using overlays but they are important for debugging a circuit board.

    Soldermask Layer 

    A soldermask layer saves the PCB traces from short connections. You can find them on the upper and lower parts of LED circuit boards.

    What Are The Electrical Properties Of LED PCB?

    LED PCB board designs offer outstanding electric properties that promote the device’s performance to a certain level. The most significant electrical properties of LED circuit boards are-

    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.
