A Guide to PCB Material Selection

Materials are critical for manufacturing a reliable PCB. The performance, shelf-life, and cost of a PCB are determined by the materials used in its stackup. Choosing the right materials is essential to ensure the intended functionality of the final product. Your typical PCB consists of one or more layers of copper, laminated between sheet layers of a non-conductive substrate. The PCB serves as the physical foundation upon which your electrical components, conductive traces, pads, and other features will reside.

When it comes to PCB, you are looking for a material that has low Dk values to act as an insulator for the copper traces and power planes. In addition, the chosen material should maintain as much of a constant Dk as possible during its lifecycle for different frequency ranges.
