Abstract
Accurate material information is very important in PCB (Printed Circuit Board) design. In an integrated mast of a battleship, heat reduction is essential for stealth functionality. So heat dissipation from internal control equipments should be reduced as much as possible. Control equipments mostly consist of PCBs, but it often suffers from impedance mismatching due to imprecise Dk (Dielectric Constant), which significantly increases heat dissipation. In this paper, measurement methods of Dk is investigated. Also, effects on impedance mismatch by Dk variation with operating frequency is investigated.
