Things that make up the RO4360 PCB Material
Below are the components used by the manufacturers in making rogers ro4360.
Copper foil: These are traces found on the RO 4360 PCB. They are conductive in nature.
Prepreg: The prepreg is a sticky B stage material and ensures the bonding of different foils or laminates.
Copper Laminates (Core): This core is made up of copper coils and prepregs, which you must cure and laminate.
Properties of the Rogers RO 4360 PCB
The properties of this PCB include:
Coefficient of Thermal Expansion
This is denoted as CTE. This measures the rate at which the expansion of a PCB material takes place whenever it heats up. It is expressed in ppm (parts per million), which expands for every degree Celsius of heat. It is measured in PPM/oC. Anytime the material’s temperature rises higher than the Tg, there will be a rise in CTE as well.
This is denoted as k. This property tells the material’s capability to conduct heat. When the thermal conductivity is low, it means the heat transfer is low, and vice versa. This property is measured in Watts/meter Kelvin.
Glass Transition Temperature
This is denoted as Tg. This temperature is one at which the substrate changes into a deformable and soft state from the glassy rigid state. It is measured in degrees Celsius.
Decomposition Temperature
This temperature is where the material will decompose chemically. It is also measured in degrees Celsius.
Relative permeability (Er) or Dielectric Constant (Dk)
This value is the ratio of the electric permeability of the material to that of free spaces.
Dissipation factor (Df) or Loss Tangent
This value is the tan of the phase angle, which is between the reactive and resistive currents of the dielectric. There is an increase in dielectric loss whenever the dissipation factor increases. A dissipation factor that is low delivers fast substrates, while dissipation factors that are large deliver slow substrates.
Can RO 4360 be used for Multi-layer PCB?
Sure, it is possible to form a multilayer PCB after applying some RO 4360 together. The RO 4360 provides a low level of interference and high signal integrity. In every multilayer PCBs, there must be at least three conductive layers.
The production of multilayer PCB requires the lamination of the core items and prepeg’s alternating layers at high pressure and temperature. This makes sure that no air stays between the layers, and also ensures that these layers are held by resin.
What to do when Choosing the Rogers 4360
There are things to do before choosing rogers 4360, these include:
Make sure there is a match in the Coefficient of Thermal Expansion: The coefficient of thermal expansion is a very important thermal trait when dealing with substrates. Difference in the CTE rates tells that during fabrication, they will expand at different rates.
Choose Materials Having Similar Dielectric constant: Make sure you go for substrates having identical dielectric constant.
Go for Tight and Flat Substrate Weaves: Doing this makes it great for high-speed and high-frequency usages. Also, it offers an even distribution of the dielectric constant.
Choose Low Moisture Absorption Materials: Moisture absorption has to do with the PCB material’s resistance when it is submerged in water. There will be an increase in the PCBs weight as the material gets absorbed in water and it falls within the range of 0.01 and 0.02%.
Avoid Using FR-4 for Applications Requiring High Frequency: Don’t do this, because their dielectric loss is high. In addition, there is a sharp Dk when compared to the frequency response curve.
