Rogers DiClad 880 PCBs are woven fiberglass reinforced, PTFE-based composites (without ceramic fillers) that offer lower dielectric constant and dissipation factors by using fewer plies of woven fiberglass and a higher ratio of PTFE content. Their DK and DF value are similar to RT/duroid 5880.

The dielectric constant of the circuit boards is adjusted by the precise control of the woven fiberglass and PTFE mixed ratio. The more the fiberglass, the larger the dielectric constant, however, the size stability is better. The woven fiberglass in the boards is stacked in the same direction to keep the performance of the XY direction consistent. Because of the use of woven fiberglass reinforcement, the size stability is better than RT/duroid 5880 and RT/duroid 5870 in the XY direction, but their thermal expansion coefficient in the Z-axis direction is larger.
