It’s designed for use in high reliability, high power/heat applications where consistent electrical performance and high thermal conductivity are required. While the specific manufacturing and fabrication processes are proprietary to Rogers Corporation, here is a general overview of how such laminates are typically made and fabricated:

Impregnation: The fiberglass cloth is impregnated with a thermosetting epoxy resin. This resin is typically mixed with a hardener and a filler that enhances thermal conductivity.

Pre-Pregging: The impregnated cloth, also known as pre-preg, is partially cured to a “B-stage” where it is dry but can still bond to other layers.

Lamination: Multiple layers of pre-preg are stacked together and covered with copper foil on both sides. The stack is then placed into a lamination press where it is subjected to heat and pressure. This fully cures the epoxy, bonding the layers together into a rigid laminate.

When fabricating circuit boards from laminates like Rogers TC350 Plus, the following steps are generally involved:

Cutting: The laminate is cut to the desired size.

Drilling: Holes are drilled for through-hole components and vias.

Copper Plating: The drilled holes are electroplated with copper to create electrical connections between layers.

Etching: The copper on the surface of the laminate is etched away using chemicals to create the desired circuit pattern.

Solder Masking: A solder mask is applied to protect the circuitry and prevent solder bridging during assembly.

Silkscreening: Component references and other markings are printed onto the solder mask.

Assembly: Components are soldered onto the board, completing the fabrication process.

It’s important to note that due to the high thermal conductivity and specific characteristics of Rogers TC350 Plus material, attention must be paid to the heat management during fabrication, as overheating can lead to deformation or other defects.

How Rogers TC350 Plus Laminates Reduce Insertion Loss?

Rogers TC350 Plus laminates are designed to reduce insertion loss primarily through their low dielectric constant (Dk) and low loss tangent (Df). Here’s how these properties contribute to the reduction of insertion loss:

Low Dielectric Constant (Dk): The dielectric constant of a material determines the speed at which electrical signals propagate through it. Lower Dk values result in faster signal propagation, which reduces the time it takes for signals to travel from one point to another. This faster signal speed helps to minimize phase delays and reduce insertion loss.

Low Loss Tangent (Df): The loss tangent, also known as the dissipation factor, measures the amount of energy that is lost as heat when a signal passes through a material. A low loss tangent indicates that the material has low signal attenuation and minimal energy loss. In high-frequency applications, low Df values are crucial for maintaining signal integrity and reducing insertion loss caused by signal absorption.

By combining a low dielectric constant and a low loss tangent, Rogers TC350 Plus laminates provide excellent electrical performance at high frequencies. These properties help to minimize signal loss, maintain signal integrity, and reduce the overall insertion loss within the circuit.

It’s important to note that other factors, such as the design of the circuit, trace geometry, and transmission line structures, also impact insertion loss.
