Abstract:
Disclosed herein is a method of manufacturing a glass core capable of continuously manufacturing the glass core by an automated process. The method includes: providing a glass sheet; laminating an insulating sheet on the glass sheet; laminating a copper clad sheet on the insulating sheet to manufacture the glass core; laminating a buffering sheet on the copper clad sheet; pressing and temporarily hardening the buffering sheet; delaminating the temporarily hardened buffering sheet; thermally hardening the glass core by a heater after the delaminating of the temporarily hardened buffering sheet; and cutting the glass core at a predetermined size after the thermal hardening of the glass core.
Abstract:
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.
