PTFE material has excellent electrical performance index, it is very suitable to be the insulating layer of CCL.
Polytetrafluoroethylene (PTFE) has the characteristics of high temperature resistance, and the operating temperature reaches 250°C. In a wide frequency range, the dielectric constant and dielectric loss are very low, and the breakdown voltage, volume resistivity and arc resistance are high, so it is an ideal PCB material.
