Preparation and Dielectric Characteristics of PTEE(Polytetrafluoroethyl one) Composites for Microwave Circuit Board
The PTFE composites for the microwave printed circuit board were prepared using woven glass fiber. The dielectric constant of the PTFE composites with oven glass fiber tended to decrease with an increase of immersion time, and was saturated at 3 times immersion. It resulted from the fact that fine powders of PTFE filled up at the pore and bend of woven glass fiber sufficiently. As the immersion time increased, the propagation velocity increased due to the reduction of dielectric constant.
Key words: microwave PCB(Printed Circuit Board), PTFE composite, Woven glass fiber, Propagation velocity
