What are RF & Microwave Laminates?
A Laminate is a material used as the substrate of a PCB board or board on which the circuit is printed or created. It is an insulating layer made up of woven, fabric, fiberglass or paper which are then fixed together to form a single sheet of uniform thickness by applying adequate pressure and temperature with the help of a resin. The laminate can be seen on the edges of a PCB board since it’s covered with Conductive Copper, Solder mask, and Silkscreen layers.
RF & Microwave Laminate are designed to perform at higher frequencies. When selecting a laminate we must consider the following parameters:
Dissipation Factor (Df): This is a measure of loss of energy in the laminated. The lower the Dissipation Factor the lower the signal loss and the better the laminate.
Dielectric Constant (Dk): This is the ratio of the permittivity of a substance to the permittivity of free space. It is a dimensionless value and is also called relative permittivity.
Transition Temperature (Tg): This is the maximum temperature at which the laminate can operate. i.e it is the temperature at which the laminate transitions from a usable material to a non-usable material.
Thickness: This is the thickness of the laminate material.
