Once the substrate is prepared, a layer of copper foil is laminated onto it. The copper foil is carefully bonded to the substrate using heat and pressure, ensuring a strong and uniform bond between the two materials.

After the copper foil is laminated onto the substrate, the material is drilled to create holes for the components. The holes are then plated with copper to create electrical connections between the layers of the board.

Next, a layer of photoresist is applied to the surface of the copper foil. The photoresist is then exposed to ultraviolet light through a photomask, which creates a pattern on the surface of the material. The areas of the copper foil that are not covered by the photoresist are then etched away, leaving behind the desired circuit pattern.

Finally, the material is coated with a layer of solder mask, which protects the copper traces and pads from oxidation and other forms of damage. The solder mask is then cured using heat, creating a durable and protective layer that is essential for the material’s long-term reliability.

Overall, the manufacturing process for the Rogers RT/duroid 6202PR is a complex and precise process that requires specialized equipment and expertise.
