CORE OF PRINTED CIRCUIT BOARD AND METHOD OF MANUFACTURING THE SAME |
摘要 |
Disclosed herein is a core made of a glass material so as to be capable of preventing generation of warpage in a printed circuit board due to a difference in a coefficient of thermal expansion at the time of manufacturing the printed circuit board. The core includes: an organic cloth; and a glass having the organic cloth formed therein. The core is manufactured in a form in which rigidity thereof is increased by impregnating the organic cloth having a negative coefficient of thermal expansion is impregnated in a liquid-phase glass, thereby making it possible to effectively prevent generation of warpage in the printed circuit board due to the difference in a coefficient of thermal expansion. |
