Manufacturing and characteristics of copper clad laminates based on glass cloth and polytetrafluoroethylene

This study concerned the manufacture of copper clad laminates using glass cloth/pol ytetrafluoroethylene(PTFE), and the effects of silane treatment on the flexural strength and morphology of the resulting prepregs. About 40 wt% glass cloth in PTFE gave the highest flexural strength. The adhesion to copper was greatest when the glass cloth content was 20 wt% in the prepregs. Finally, the prediction of the dielectric properties was discussed.
